The refrigerant is cooled before it moves through the expansion device and into the evaporator. A refrigerator compressor relay is a vital part of the process of refrigeration. Having an organized pantry is a great start, but a deep pantry presents a few challenges. The working of overload relay is simple whenever the compressor motor getting heat up, due to the overload connected with the compressor body, the internal overload heating resistance heat up and due to heat up the bimetallic strip metals cut up the connection between one another and its make compressor circuit to an open electric circuit. We have received your CertCapture request form for . These indicators can include: Any of these sounds or smells emanating from your refrigerator can be a bad sign. Under normal operation this breaker will trip as described and self reset after a few minutes. If the reading exceeds 1 ohm, replace the PTC relay.

The overheat sensor will shut the compressor off to prevent damage. Replace the panel over the compressor and mount the screws tightly. Relay Solution. If you hear the usual click and hum as the compressor starts, you know the bypass was successful. If you suspect that this is the case, you must consult with a licensed electrician to make the necessary repairs to your home wiring to handle the higher needs. The problem may just be a bad overload or compressor relay. Take the red probe and plug its end into the positive terminal on the multimeters bottom.

The relay coils wiring is in series with the compressors run winding. If your refrigerator starts and then stops, this is usually because your compressor may have an under-voltage condition with the power supply or your compressor may be failing. Dont ignore such signals as a compressor that starts and then stops. And if there is a burnt odor coming from it, replace the relay because it is damaged. To fix the problem of a fridge compressor tripping overload, you may have to replace the compressor. As soon as the compressor starts, the contacts open again and remove the start circuit.
