FREEZER SIDE VIEW

AIR FLOW - FORCED AIR SYSTEMS
The airflow balance between the fresh food and freezer compartments is an important factor in maintaining proper compartment temperatures in a forced air refrigeration system. A baffle is used to regulate the amount of chilled air directed into the fresh food compartment. If a colder freezer compartment temperature is desired, the baffle is adjusted so that less air is directed into the fresh food compartment. This causes the compressor to run longer since the thermostat sensing element is located in the fresh food compartment. Cold air is drawn across the evaporator and into the fan. A portion of the air is deflected into the fresh food compartment where it absorbs heat and returns to the fin and tube evaporator
Maytag Corporation SECTION 1. GENERAL INFORMATION
through the return opening in the divider. However, most of the air moving across the evaporator is blown through the freezer air tunnel and circulated throughout the freezer compartment. It then circulates back across the fin and tube evaporator where it begins another cycle.
overload. Because some models can hold the entire charge in the condenser, the compressor may run continuously and a definite vacuum will be noticed in the low side. When moisture freeze-up causes a restriction, it usually occurs at the outlet end of the capillary tube. Normally, frost buildup can be detected in this area. NOTE: When using a heat gun or hair dryer, use low heat. Never use a torch. At the discharge end of the capillary, apply heat. If there is enough head pressure, and if the restriction is caused by moisture freeze-up, you will be able to hear a gurgling noise as the heat releases the refrigerant through the tubing. It is possible that this moisture will be absorbed by the drier and remedy the trouble. However, if the freeze-up reoccurs, you must replace the drier. A kink in the capillary tube will reveal the same symptom as a moisture freeze-up, except for the accumulation of frost. Where possible, check the capillary tube and straighten any kinks to relieve the restrictions. Check the unit operation. If the condition persists, replace the defective part. If the freeze-up condition does not exist and there is not a kink, you can assume that a foreign particle is causing the restrictions. The only remedy in this case is to replace the restricted part.

SYSTEM FLUSH - Flushing of the system is required whenever there has been a low side leak, plugged capillary tube or compressor replacement. This is a procedure in which R134A refrigerant is flushed through the system and into the recovery system to remove moisture and noncondensables which may have entered the open system. The compressor must be isolated during the flush procedure, in order to prevent contaminants from being absorbed into the ester oil, resulting in a contaminated system.
The system flush procedure will be done in two parts. First, the condenser, including the yoder loop, will be isolated by means of process tube adapters and flushed with 4 ounces of R134A. After the drier has been replaced, the entire sealed system, minus the compressor, will also be flushed with 4 ounces of the refrigerant. This second step can take about 15 minutes in order to circulate the refrigerant through the condenser, the drier, the capillary tube, the evaporator and out the suction line into the recovery equipment. During this 15 minutes, the old compressor can be removed and the replacement set into place, mounted and prepared electrically. The compressor is totally installed except for the final brazing of the suction and discharge lines.

REFRIGERATION SYSTEM

All refrigerators cool by removing heat from the cabinet rather than pumping in cool air. In a conventional refrigerator, liquid refrigerant enters the evaporator and vaporizes (boils) due to the low pressure, creating a very cold surface which removes heat from inside the cabinet. This causes the refrigerant to boil (evaporate) into a vapor state and be drawn into the compressor. The compressor pressurizes the vapor and pumps it into the condenser. The hot vapor in the condenser gives off the heat into the room. As the vapor cools, it condenses back into a liquid and returns to the evaporator to start the process over again. The system continually soaks up the heat inside the refrigerator and deposits the heat back into the room. The compressor of the refrigeration system serves two purposes: it ensures movement of the refrigerant throughout the system and it increases the pressure and temperature of the vapor received from the suction line and pumps the refrigerant into the discharge line. The condenser receives this high temperature, high pressure refrigerant and allows the heat to be released into the cooler surroundings. This heat removal "condenses" the refrigerant vapor into a liquid. The yoder loop is the last pass of the condenser routed around the cabinet of the freezer to help prevent moisture formation. The drier is installed at the end of the condenser or yoder loop to capture moisture which may be present in the system.

The capillary tube meters the flow of refrigerant and creates a pressure drop. Size and length of the capillary is critical to the efficiency of the system. As the refrigerant leaves the capillary tube and enters the larger tubing of the evaporator, evaporator the sudden increase in tubing diameter, and the pumping action of the compressor, form a low pressure area. The temperature of the refrigerant drops rapidly as it changes to a mixture of liquid and vapor. In the process of passing through the evaporator, the refrigerant absorbs heat from the storage area and is gradually changed from a liquid and vapor mixture (saturated refrigerant) into a vapor. The suction line returns this low pressure vapor from the evaporator back to the compressor, and the cycle starts again. Part of the capillary tube is soldered to the suction line which forms a heat exchanger. Heat from the capillary tube is thus transferred to the suction line to superheat the refrigerant there and at the same time this further cools the liquid in the capillary tube. This cools the refrigerant before it enters the evaporator and also heats the refrigerant before it enters the compressor to ensure a vapor state.

DIAGNOSIS

Sealed system diagnosis of R134A refrigerant systems is to be performed identically to that of R12 systems. In fact, as shown in the following flow chart, the service procedures are virtually the same, except for low side leaks, plugged capillary tube or compressor failure which results in a system flush.

REFRIGERATOR DIAGNOSIS

LISTEN: What is the customer complaint? Are the fans operating? Is the compressor operating? LOOK: Are ice cubes present? Is the light on/off when the switch is operated? Are the controls set properly? Do door gaskets seal properly? Is there an ice buildup on the evaporator cover? Are the return air ducts free of ice? TOUCH: Is the evaporator cover warm? Is air felt exhausting from the kick plate? Is air circulating in the freezer and fresh food compartments? Is the quarter inch discharge line from the compressor hot? Is the condenser warm?

SEALED SYSTEM DIAGNOSIS

Once it has been determined that the other refrigerator systems are working properly, a probable sealed system problem can be confirmed through the use of a wattmeter and checks of low and high side pressures. Access valves are not to be left on a sealed system after service. To measure low side pressure, a temporary access valve can be installed on the compressor process tube. To remove the valve after repair, a pinch off tool may be used to seal the tube while the valve is removed and the hole brazed shut. To check high side pressure, a temporary access valve should be installed on the discharge line. When the high side valve is inSECTION 1. GENERAL INFORMATION

SYSTEM FLUSH

Before accessing the sealed system, it is necessary to determine that the problem is actually a sealed system problem by utilizing a wattmeter, thermometer, visual and touch indicators. Once it has been determined that the problem is in the sealed system, and diagnosis indicates a low side leak, plugged capillary tube, or a defective compressor, in addition to the normal repair, the system must be flushed and the compressor must be replaced.
SEALED SYSTEM REPAIR SUMMARY
A. Recover the refrigerant in the system, if any. Repair the low side leak or replace the evaporator and heat exchanger, whichever applies. If the complete low side is replaced, do not braze the suction line to the replacement compressor until the completion of Step 3 of System Flush Procedure. Proceed with the following flush procedure which includes the compressor replacement. After flushing procedure is completed, continue with the normal sweep and final charging procedure.
Next, score and break the tube at the yoder loop to the input side of the drier. Attach a process tube adapter to the condenser side of this break. Connect a quick coupler hand valve to this process adapter. Connect the hose from the recovery equipment to this valve (figure 1). Use the heater on the charging cylinder to ensure the cylinder pressure to be approximately 30 pounds above room ambient temperature. For example, if room temperature is 70 degrees, cylinder pressure should be 100 p.s.i.g. Start the recovery system and open the valve at the process adapter attached to yoder loop. Open the valve from the charging cylinder and allow 4 ounces of R134A to flow through the condenser and into the recovery system. This process should take about two minutes. Keep the process adapters and hoses attached at this time.

SYSTEM FLUSH PROCEDURE

1. Isolate and flush the Condenser Score and break the discharge line at a convenient location to which the replacement compressor tubing can be connected later. Attach a process tube adapter to the condenser side of this break. Connect a quick coupler hand valve to the process adapter. Connect the hose from the charging cylinder to this valve (refer to figure 1). This connection will remain in place throughout the flush procedure in Step 3. NOTE: Due to the extra flushing and sweep charge procedures, about 12 ounces of R134A refrigerant should be added to the original charge specified on the model/serial plate and loaded into the charging cylinder initially.

During final flush, remove old compressor, and install replacement compressor leave plugs in place until brazing.
4. Complete compressor replacement Close valves to the recovery system. Remove process tube adapters from both the suction and discharge lines. Connect and braze suction and discharge lines to the replacement compressor (figure 5). You are now ready to add the temporary piercing valve to the drier process line and proceed with the sweep and final charging of the system.
CAUTION In order to prevent sealed system contamination, the time of atmospheric exposure must be limited to 15 minutes. do not pull the plugs from the new compressor until you are ready to make the connections.

FIGURE 5

Flush complete - ready for sweep charge.

SWEEP AND FINAL CHARGE

The sweep charge is a method of purging the sealed system of moisture, air and potential contaminants. Also during this procedure, the system may be checked for leaks before the final charge. If this procedure is followed as outlined, it will allow for the capture of 90-95 percent of the available refrigerant, thereby ensuring that the system will operate as designed. The sweep procedure for R134a refrigerant systems is made after the system has been repaired and/or flushed. Three (3) ounces of refrigerant R134a is added to the system, circulated by the compressor for 5 minutes and recovered. Since a new drier - part
#13900-1 has already been installed, a high side process tube is available. Install a temporary access valve to this process tube close enough to the end of the tube so that the tube can be pinched closed behind the valve and the opening sealed shut after the valve is removed. Remember, no access valve is to be left on the sealed system. Connect a 1/4 inch flare tee to the access valve. Connect a quick coupler hand valve to each side of the tee. To one hand valve, connect the hose from the charging cylinder. To the other valve, connect the hose to the recovery system. The following steps take you through the sweep and final charge.
Step 1. Set up of valves: temporary access valve (C) piercing drier process tube, connected to flare tee, hand valve (A) to charging cylinder, hand valve (B) to recovery system. ACCESS VALVE TO CHARGING CYLINDER

Disconnect lead wires from compressor terminals. Remove the retaining clips from the compressor mounts. Remove defective compressor from cabinet and install rubber grommets on replacement compressor. Clean the compressor stubs with an abrasive cloth such as grit cloth No. 23. Do not open the compressor stubs. Install the replacement compressor using the mounting clips previously removed. Connect the compressor leads. Solder a short piece of tubing to the process tube (approximately 6 inches long). Connect the refrigerant tubing to the compressor stubs using silfos on copper to copper joints and silver solder and flux on steel to copper joints.
Cut the inlet tube of the replacement drier and use pliers to snap off the scored end. Install the new drier using silver solder with the proper flux at the Yoder tube to drier joint. Use silfos at the drier to capillary tube joint.
Locate and remove old drier. Install new drier. The new driver is installed in the following manner:
a. b. Carefully bend the old drier and tubing away from electrical parts. Use steel wool or fine emery paper to clean the capillary tube 3 inches from the original joint. Also, clean the input tubing to the drier of 3 inches from the original joint. Use steel wool or fine emery paper to clean both ends of the new drier. Use a knife or file to score the capillary tube 1 inch from the original joint. Use your finger to break the connection. Make an offset 1/2" from the end of the cap tube to prevent it from penetrating too far into the drier.
10. Evacuate, recharge and leak test the system. 11. Test run the unit to check operation 12. Replace the machine compartment cover.

CONDENSER REPLACEMENT

The following general information explains how to successfully replace the condenser for any model covered in this manual.

1. 2. 3.

Disconnect the unit from the power source. Remove all loose items from the refrigerator interior. Working at the back of the cabinet, remove the cover from the machine compartment. It is necessary to reinstall this cover after the job is completed. Using a sponge, remove any drain water from the defrost pan. With assistance, tilt the cabinet back and remove the front condenser mounting screw.

We recommend using a capacitor analyzer when testing. A solid state unit that measures capacitance and power of any capacitor, and has an automatic means of discharging the capacitor through resistance is preferred.
Alternate Method Using Ohmmeter
1. 2. 3. Disconnect the unit from the power source. Disconnect the capacitor lead wires. Short across the terminals using a resistor with a minimum resistance of 1,000 ohms. This ensures that no charge remains to damage the ohmmeter. Set the ohmmeter selector switch to the 10,000 ohm scale (R x 10K). Connect the ohmmeter leads to the capacitor terminals and observe the meter point lower end.
If the pointer deflects to the lower end and remains there, the capacitor is shorted and must be replaced. If there is no deflection of the pointer, the capacitor is open and must be replaced.
If the pointer deflects toward the high end of the scale and then slowly returns to the low end, the capacitor is good.

TEMPERATURE CONTROL

The refrigerator has two temperature controls: 1. Fresh Food Compartment - The fresh food temperature control senses the temperature of its compartment and governs the compressor operation accordingly. Freezer Compartment - The freezer compartment control adjusts the damper door which regulates the amount of air allowed to enter the fresh food compartment.
Conversely, by turning the freezer temperature control to the warmest setting, you increase the flow of air into the fresh food compartment and decrease the flow to the freezer. This cools the fresh food temperature control sensing element faster, resulting in shorter compressor run times and warmer freezer compartment temperatures. The fresh food compartment will stay near the recommended fresh food temperature, unless the freezer temperature is turned to an extreme temperature. The differential between cut-in/cut-out temperature will vary approximately 100F.
Turning the freezer temperature control to the coldest settings reduces the flow of chilled air to the fresh food compartment. The fresh food temperature control uses a sensing element that must be cooled sufficiently before stopping the compressor. The reduced air flow causes longer compressor run time and colder freezer temperatures, while maintaining the required fresh food compartment temperatures.
Checking Operating Temperatures
The temperature control feeler tube is located in the fresh food compartment. The feeler tube is wrapped around a thermal mass located in the back left corner of the control housing. A small amount of air passes over the thermal mass which gives a consistent run time during ambient changes.

To check the cut-in/cut-out temperatures, attach the bulb of thermistor temperature tester to the control feeler tube and set controls at midposition. Allow the compressor to complete two or three complete cycles. If the temperature readings are not within two degrees of the requirements the control is defective and must be replaced. Do not attempt to recalibrate. A defective control may cause the compressor to run continuously or not at all. If either of these conditions exist, check as follows:

Compressor Runs Continuously
Turn the control knob to OFF. If the compressor continues to run, proceed to step 2. If the compressor stops, check that the feeder tube is positioned properly and that the air flow through the control housing is not restricted. If the feeler tube is positioned properly and there is no air restriction, check the control operating temperatures. Remove the control far enough to remove one of the wires from its terminal. If the compressor continues to run, there is a short in the unit wiring.

Compressor Won't Run

1. 2. Remove the control enough to expose its terminals. Short across the control terminals. If the compressor starts, install a new control. If the compressor fails to start, check the defrost timer, compressor receptacle, and unit wiring for defects.
Temperature Control Replacement
1. 2. 3. Disconnect the unit from the power source. Open the fresh food door and remove any loose items on the top shelf. Remove the light shield cover by pulling down on the back corners of the cover, and sliding the cover forward.
Remove the control housing mounting screw at the back of the control housing. Slide the control housing to the right and lower from control housing supports. Disconnect the temperature control housing electrical quick disconnect. Remove the temperature control housing from the refrigerator and place on a flat work surface. Remove the control knob by pulling it away from the temperature control. Remove the electrical and ground leads from the temperature control terminals. Remove the control by pushing on the tab with right thumb to release the lock. With the left hand, rotate the control out of its locking tabs.
AUTO DAMPER CONTROL MODELS
The Auto Damper model refrigerator has two controls and both have capillary sensing. The Auto Damper controls the fresh food temperature and the Freezer Temperature Control guides the freezer temperature. The fresh food compartment temperature is maintained by a damper assembly located at the back of the temperature control housing. Changes in air temperature cause the damper door to open and close. A control rod and gear connect the fresh food control knob to the damper control. Turning the fresh food control knob to the COLDEST position increases the flow of freezer air into the fresh food section. The freezer compartment temperature control warms at a faster rate and cools at a slower rate, increasing the compressor run time necessary to maintain a satisfied freezer temperature control. Turning the fresh food control knob to a WARMER setting decreases the flow of chilled air into the fresh food section. The freezer compartment temperature control warms at a slower rate and cools at a faster rate, decreasing the compressor run time necessary to maintain a satisfied freezer temperature control.

7. 8. 9.

10. To remove the thermal mass, insert a flat bladed screwdriver between the thermal mass and the control housing area. Turn the screwdriver to release the mass from its locking tab. 11. Install the replacement control in the reverse order of removal.

Checking the Auto Damper

1. 2. 3. 4. Disconnect the unit from the power source. Open the fresh food door and remove any items on the top shelf. Set the fresh food control to the coldest position. Remove the light shield cover by pulling down on the back corners of the cover and sliding the cover forward. Remove the fascia/radiant shield mounting screws. Remove the control housing mounting screw at the back, bottom center of the control housing. Slide the control housing to the right. Lower the control housing.

DEFROST TIMER

The freezer evaporator defrosting system is actuated by an electric timer. The timer is mounted in the control housing located in the fresh food compartment.

Defrost Timer

The timer control shaft is designed for screwdriver advancement. When manually setting the timer to initiate defrosting, turn the control shaft clockwise until you establish the approximate location of the defrost cycle. Then turn the shaft slowly, and stop immediately when the first click is heard. The schematic illustrates the timer circuits in sequence.
1st Click - The timer turns off the compressor and freezer fan circuit for approximately 23 minutes, and it energizes the defrost heater. Once the temperature of the defrost termination thermostat reaches the cut-out point, the termination thermostat will open the circuit to the radiant heater. However, the compressor circuit remains open for the duration of the defrost interval. 2nd Click - The timer switches off the defrost circuit and starts the compressor, freezer fan, and the condenser fan motor. The compressor and fan motors are now governed by the temperature control for a period of approximately 8 hours of the compressor run time, after which a new defrost cycle begins.
