How To Tell If Refrigerator Compressor Relay Is Bad. Shake it near your ear once more to listen for a rattling noise, so you can confirm that it’s faulty. If your refrigerator hums loudly, dims the lights, trips a circuit breaker or blows a fuse every time it tries to start, the problem may be a.
Shake the relay in your hand and listen for a rattle. If it makes any clunking noise whenever the compressor shuts off, that is another bad sign for the compressor. The main job of the relay system is to kick the refrigerator’s compressor into gear.
If You Can Hear Rattling On The Inside Of The Start Relay , Then The Part Is Bad And Will Have To Be Replaced.
If your refrigerator hums loudly, dims the lights, trips a circuit breaker or blows a fuse every time it tries to start, the problem may be a. You can tell that the start relay is bad if the fridge won’t cool or the relay makes a clicking noise. Unplug the start relay from the compressor and give it a shake.
A Physical Test Of The Start Relay Can Be The Most Effective Way To Determine Whether It's Working Or Not.
Look at the relay switch. Then, replace it with the new compressor relay. Power is applied to the compressor motor windings through the overload device, and the relay is used to add the start winding in the circuit until the compressor is at running speed.
If There Is No Rattle, Then It’s Likely The Relay Is Fine But The Compressor Is The Issue.
The compressor itself located the back panel at the bottom of the refrigerator. The clunking or knocking noise indicates faulty parts of the compressor. We show how to test a start relay for continuity and resistance, h.
If It Makes Any Clunking Noise Whenever The Compressor Shuts Off, That Is Another Bad Sign For The Compressor.
To tell what is happening, test the compressor motor. All this is further explained here. You will need to order a replacement part.
If It Makes A Rattling Sound, It Is Most Likely Faulty.
