The part(s) or condition(s) listed below for the symptom Freezer not working, clicking sound are ordered from most likely to least likely to occur. Check or test each item, starting with the items at the top of the page.
The start relay provides power to the compressor. If the start relay isn’t working properly, the compressor may run intermittently or not at all. If the compressor won’t run, the freezer will not cool. To determine if the start relay is defective, unplug the freezer and remove the start relay from the compressor. Use a multimeter to test the start relay for continuity between the start and run terminals. If the start relay does not have continuity, or if it smells burnt, replace it.
The compressor is a motor which compresses the refrigerant and circulates the refrigerant through the evaporator and condenser coils. Use a multimeter to test the continuity between the electrical pins on the side of the compressor. If there is an open circuit, the compressor is defective. If the compressor is defective, it must be replaced by a licensed technician. If the compressor does not appear to be defective, test the start relay and run capacitor. If the start relay or run capacitor are defective, they will prevent the compressor from running.
