How many ohms should a compressor relay have?
Ohmmeter should indicate between 1 and 5 ohms. Measure between each terminal and the compressor body. Ohmmeter should indicate infinite resistance (1). Any other reading would indicate a shorted compressor.
How do you bypass a compressor relay on a refrigerator?
You must make use of a flathead screwdriver to press down on the area between the relay and its container. Next, press on the relay itself and drag it out to disengage it from the refrigerator. Then unplug the wire from the relay so it is convenient.Nov 1, 2021
