Testing the Overload Protector
The overload protector is a security system that journeys if the compressor overheats or attracts an excessive amount of present. To check the overload protector, unplug the fridge and take away the again panel. Find the overload protector, which is normally a small black or silver system hooked up to the compressor. Use a multimeter to check the continuity of the overload protector’s terminals. If there is no such thing as 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 could not activate or off as wanted. To check the thermostat, unplug the fridge and take away the again panel. Find the thermostat, which is normally 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 is no such thing as a continuity, the thermostat is defective and must be changed.
Checking the Wiring
If all different elements take a look at high-quality, the wiring could also be defective. To test the wiring, unplug the fridge and take away the again panel. Examine the wiring for any cuts, breaks, or unfastened connections. When you discover any broken wiring, it’s going to have to 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 is not going to obtain energy and the compressor is not going to activate.
Checking the Begin and Run Capacitors
The beginning and run capacitors present further energy to the compressor to start out and run easily. If both capacitor is defective, the compressor could not activate or could not run correctly. To check the capacitors, unplug the fridge and take away the again panel. Find the capacitors, that are normally 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’s going to have to be changed.
Inspecting the Evaporator Coils
The evaporator coils are situated on the again of the fridge cupboard. They will turn into clogged with frost or ice, which may stop the compressor from working correctly. To examine the evaporator coils, unplug the fridge and take away the again panel. Examine 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 Widespread Issues
In case you are having hassle changing the fridge compressor, seek the advice of the next desk for frequent issues and options:
| Drawback | Resolution |
|---|---|
| The compressor doesn’t run | Examine the facility supply, compressor, relay, and overload protector |
| The compressor runs however the fridge doesn’t cool | Examine the thermostat, evaporator coils, and condenser coils |
| The compressor runs too usually or too lengthy | Examine the condenser coils, thermostat, and door gaskets |
