Refrigerator Making Clicking Noise

If your Refrigerator is Making Clicking Noise Check the Following

Start Relay

The clicking could be the start relay/ ptc / relay. If the start relay/ptc relay is bad, the compressor will not start and you will hear a clicking noise in 2-5 minute intervals. The clicking noise is the overload cutting the compressor off when it overheats from trying to start with a bad start rela/ptc relay. To find out if this is bad first unplug the refrigerator. Remove the lower rear cover from your refrigerator. Then take the cover off. The start relay/ptc relay is on the side of the compressor, you will see wires going to this. Unplug the wiring. Now the easy way to tell if it is bad is to shake it. If it rattles, it’s bad and needs to be replaced. Inspect it carefully for any burn marks or smells burnt if it has any replace it. If not, most of the time it’s ok.

Rather than saying the compressors bad, you might want to replace it anyways because it does not cost much. A quick check on the compressor is to remove the start relay. You will see 3 pins connect a multi meter set for continuity. You should have continuity between any of the 3 pins. If you do not the compressor is bad. Also check from each pin to a good ground on the cabinet. There should be no continuity if there is the compressor is bad. A 3 in 1 start relay can also be used as a substitution. The 3 in 1 start relay plugs into the 3 terminals on the compressor and the other 2 leads connect to the old relay. Just make sure it is rated for the horsepower of the compressor. If you replace it and it doesn’t work, then the compressor is bad and you’ll need you call a repairman. (Note that compressors are very costly and are normally not worth fixing).
