To check the overload protector, unplug the fridge and take away the again panel. Find the overload protector, which is often a small black or silver machine hooked up to the compressor. Use a multimeter to check the continuity of the overload protector’s terminals. If there isn’t a continuity, the overload protector has tripped and must be changed.
Inspecting the Thermostat
The thermostat controls the temperature of the fridge. If the thermostat is defective, the compressor might not activate or off as wanted. To check the thermostat, unplug the fridge and take away the again panel. Find the thermostat, which is often a small white or black field hooked up to the evaporator coils. Use a multimeter to check the continuity of the thermostat’s terminals. If there isn’t a continuity, the thermostat is defective and must be changed.
Checking the Wiring
If all different parts check superb, the wiring could also be defective. To examine the wiring, unplug the fridge and take away the again panel. Examine the wiring for any cuts, breaks, or unfastened connections. In case you discover any broken wiring, it should must be repaired or changed.
Checking the Energy Supply
Make sure the fridge is plugged right into a working energy outlet. If the outlet is defective, the fridge won’t obtain energy and the compressor won’t activate.
Checking the Begin and Run Capacitors
The beginning and run capacitors present further energy to the compressor to begin and run easily. If both capacitor is defective, the compressor might not activate or might not run correctly. To check the capacitors, unplug the fridge and take away the again panel. Find the capacitors, that are often small cylindrical or oval-shaped units close to the compressor. Use a multimeter to check the capacitance of the capacitors. If both capacitor has a low capacitance, it should must be changed.
Inspecting the Evaporator Coils
The evaporator coils are situated on the again of the fridge cupboard. They will change into clogged with frost or ice, which might stop the compressor from working correctly. To examine the evaporator coils, unplug the fridge and take away the again panel. Test the coils for frost or ice buildup. If the coils are soiled, you’ll be able to clear them with a vacuum cleaner or a brush.
Troubleshooting Frequent Issues
If you’re having bother changing the fridge compressor, seek the advice of the next desk for frequent issues and options:
| Downside | Answer |
|---|---|
| The compressor doesn’t run | Test the facility supply, compressor, relay, and overload protector |
| The compressor runs however the fridge doesn’t cool | Test the thermostat, evaporator coils, and condenser coils |
| The compressor runs too typically or too lengthy | Test the condenser coils, thermostat, and door gaskets |
