If all different elements take a look at nice, the wiring could also be defective. To verify 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’ll should 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 additional 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 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’ll should be changed.
Inspecting the Evaporator Coils
The evaporator coils are situated on the again of the fridge cupboard. They’ll 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. Verify the coils for frost or ice buildup.
