How to Reverse a Stuck Compresser
The compressor is the heart of most refrigeration and air conditioning units. When a compressor fails, it prevents the whole unit from working properly. Replacing a compressor is costly and may require ordering a part which could turn into a long wait. One option for fixing a stuck compressor is to try and reverse its direction for a second or two. It doesn't always work, but it could free up the compressor enough to get it running again.
Turn off the power to the unit containing the compressor. Turn off the circuit breaker if the unit does not have its own power switch.
Remove the compressor's run lead with an adjustable wrench or a screwdriver. The lead should be clearly labeled with an R or the word run.
Remove the compressor's start lead. The lead should be clearly labeled with an S or the word start.
Attach the compressor's start lead to the run position and the run lead to the start position.
Turn the power to the compressor on for 1 to 2 seconds.
Turn off the power to the compressor. Replace the leads to their original position.
Turn on the power to the compressor.
