Basic Information 1-1 Section 1 Basic Information.
Basic Information 1-2 Section 1 - Basic Information .............................. 1-1 T able of Content s .................................................... 1-2 Safe Servicing Practices ........................................ 1-3 Product Features .
Safe Servicing Practices A void personal injury and/or property damage by observing import ant Safe Servicing Practices. Following are some limited examples of safe practices: 1. DO NOT attempt a product repair if you have any doubts as to your ability to complete the rep air in a safe and satisfactory manner .
Basic Information 1-4 Product Features Frigidaire refrigerator/freezers are designed for optimal convenience and storage flexibility . Use the illustration below to familiarize yourself with product features and terminology .
Basic Information 1-5 Door Storage Door bins, shelves, and racks are provided for convenient storage of jars, bottles, and cans. Frequently used items can be quickly selected. The dairy compartment, which is warmer than the general food storage section, is intended for short term storage of cheese,spreads or butter .
Basic Information 1-6 Serial Plate The serial plate is located inside the cabinet on the left sidewall. The technician should always refer to the serial plate to assure refrigerant type and quantity , as well as electrical ratings and operating pressures.
Electronic Control 2-1 Section 2 Electronic Control.
2-2 Electronic Control Electronic T emperature Control The electronic temperature controls are located on the evaporator cover in the upper right hand corner . (See Figure 3-1) The rocker switch controlling the mode of operation is mounted to the top of the evaporator cover .
Operation of Electrical Control Component s Freezer and Refrigerator Modules The modules, when selected by the rocker switch, control the temperature of the unit by an internal thermistor mounted on the circuit board. Each module has an individual service mode.
2-4 Electronic Control Service Diagnostic Mode Initiate Service Mode The refrigerator and freezer controls have individual service modes. Each control assembly has a thermistor embedded on the electronic control assembly circuit board.
2-5 Electronic Control Error Indication The following error conditions are monitored by each electronic control assembly: 1. Thermistor open or shorted. A defective thermistor will require that the affected electronic control assembly be replaced. 2. S tuck Key (the key appears to be pressed for longer than 30 seconds).

3-1 Refrigeration System Section 3 Refrigeration System.
3-2 Refrigeration System Instructions given here are furnished as a guide. Persons attempting to use these instructions to make rep airs to the sealed refrigeration system should have a working knowledge of refrigeration and previous training on sealed system rep air , and an EP A certification for servicing refrigeration systems.
1. All joints to be soldered must have proper fit. Clearance between tubes to be soldered should be from .001” to .006”. It is not practical to actually measure this; however , you do not want a dry fit or loose fit. T ubing joints should overlap about the distance of their diameter except for restrictor tubes, which should be inserted 1.
3-4 Refrigeration System Low/High Side Leak or Undercharge A loss of refrigerant can result in any of the following: 1. Excessive or continuous compressor operation. 2. Above normal refrigerator/freezer compartment temperature. 3. A partially frosted evaporator (depending on amount of refrigerant loss).
3-5 Refrigeration System T o Flush The System T o Use Dry Nitrogen T o Flush The System: 1. Remove compressor and filter-drier . Connect process coupling to outlet tube of condenser . 2. Fasten cloth over other end of coil to prevent old oil from spraying over room.
A new compressor which is cold (e.g. after having been kept in a cold service van) should be left to warm to the surrounding temperature before the plugs on the compressor connections are removed. This will help prevent condensation from forming in the oil and the compressor .
Condenser Replacement 1. Disconnect electrical supply to refrigerator . 2. Remove compressor access panel. 3. Recover refrigerant by using EP A approved recovery system. 4. Remove condenser fan mounting screws. 5. Unplug fan motor harness located in back of fan motor .
Filter-Drier Inst allation Any time the sealed system is opened and the refrigerant charge is removed, the liquid line filter-drier must be replaced and the system thoroughly evacuated before replacing refrigerant. 1. Disconnect electrical supply to freezer .
3-9 Refrigeration System Equipment Needed for Evacuation & Recharging: • Heated charging cylinder • S t andard 3-port manifold gauge set: - 4 charging hoses - T ee fitting with valve core stem removed (Robinair No. 40396) - Hand shut-off valve (Robinair No.
3-10 Refrigeration System Evacuating System T o achieve the required levels of evacuation, a properly maintained two st age vacuum pump in good condition is required. It is absolutely essential to maintain your vacuum pump according to the manufacturer ’s instructions including required oil changes at the recommended intervals.
3-11 Refrigeration System 10. Slowly open the high-side manifold gauge valve to allow the compressor to remove any refrigerant trapped in the high-side hose and the process fitting. 1 1. Close both of the manifold gauge valves. If the high-side gauge reading rises, the pinch-off must be corrected before proceeding.
3-12 Refrigeration System V erify Refrigerant T ype In The System Dedicated Equipment R-134a must not be mixed with other types of refrigerants. R-134a must be recovered in dedicated and properly identified recovery bags and tanks. It will be necessary to check with the manufacturer of your recovery equipment to determine R-134a compatibility .
3-13 Refrigeration System T o achieve the required 29.9 inch (500 micron) vacuum, a properly maintained two-st age vacuum pump in good condition is required. A two stage pump can reach a deeper vacuum than a single stage because the exhaust from the first pumping stage is discharged into the second pumping stage.
3-14 Refrigeration System V acuum Pump Maintenance It is absolutely essential to maintain your vacuum pump according to the manufacturer ’s instructions including required oil changes at the recommended intervals. V acuum pump oil should always be changed after evacuating a contaminated system.
3-15 Refrigeration System Leak Detection R-134a system leaks can be pinpointed by means of an electronic leak detector or by bubble solution. Electronic leak detectors for R-134a service are currently available from several manufacturers.
3-16 Refrigeration System HFC-134a, CFC-12 Pressure T emperature Chart.
3-17 Refrigeration System Inhalation T oxicity HFC-134a poses no acute or chronic hazard when it is handled in accordance with DuPont recommendations and when exposures are maintained at or below the DuPont Acceptable Exposure Limit (AEL) of 1,000 ppm (8 and 12 hour T ime-Weighted Average or TW A).
3-18 Refrigeration System Combustibility of HFC-134a HFC-134a is nonflammable at ambient temperatures and atmospheric pressure. However , tests have shown HFC-134a to be combustible at pressures as low as 5.5 psig (139.3 kPa absolute) at 177°C (350°F) when mixed with air at concentrations generally greater than 60% volume air .

5-1 T roubleshooting Section 5 T roubleshooting.
Refrigerator/Freezer is plugged into a circuit that has a ground fault interrupt. T emperature control is in the "OFF" posi- tion. Refrigerator/Freezer may not be plugged in, or plug may be loose. House fuse blown or tripped circuit breaker .
Modern Freezers have increased storage capacity and more st able temperatures. They require heavy duty compressors. Refrigerator/Freezer operates at higher pressures during the start of the ON cycle. Metal p arts undergo expansion and contraction, as in hot water pipes.
5-4 T roubleshooting Compressor and evapora- tor fan motor does not run. Compressor does not run, but the evaporator fan motor does. Evaporator fan motor does not run,but the compressor operates. Electronic control display does not illuminate, but the freezer operates.
5-5 T roubleshooting 1. Program the control for a manual defrost. Does the defrost operate? 2. Disconnect the orange wire from the defrost thermostat and the white wire from the defrost heater . Measure the resistance between the wire on the thermostat and the wire at the end of the heater .
