Has your refrigerator stopped producing cold air?
Is your food not being cooled properly?
There is a possibility that something might be wrong with the positive temperature coefficient (PTC) relay, also known as the start relay.
The compressor of your refrigerator keeps your appliance cool by running at irregular intervals. It is not designed to run continuously, hence the relay is used. A start relay is an electrical switch which tells the compressor when to turn on or off depending on the requirement of cool air inside the unit.
If the relay fails, the compressor might not ever turn on! Luckily, you can easily check the start relay and replace it or you can bypass the refrigerator’s relay system.
Before bypassing the start relay on your refryefteor, you need to consider some important safety measures.
- The foremost thing you should keep in mind is that bypassing the refrigerator relay is a temporary fix. Thus, you should call a professional to help fix the relay as soon as it is possible.
- The relationship between the relay and compressor of the refrigerator is quite important and helps in saving the energy. Not only it ensures that your appliance is performing all the operations properly but also that it doesn’t overheat. If the unit gets overheated, other parts of the refrigerator might go bad, wear out or overheat.
- Turn the power off and unplug your refrigerator before bypassing the start relay. After this, safely move your appliance away from the wall. Do this with precaution as refrigerators are not only heavy but also a tipping hazard.
Let us now move to the steps that you need to follow to bypass the start relay on your refrigerator.
Follow the safety instructions outlined above before following these steps.
- When you have moved the appliance away from the wall, locate the cover plate at the bottom rear of your refrigerator. Remove it with the help of a screwdriver. Keep the cover plate aside.
- Next, disengage the metal box located in the lower right rear of the appliance by pushing or flexing it. Once it has been removed, you will be able to see the relay system of the refrigerator.
- Press down on the space between the relay and its casing using a flathead screwdriver. Now, press on the relay itself and pull it out from the refrigerator.
- Sliding the wire from the relay will make it accessible. To do this, first remove the metal connector that attaches the wire to the relay system and then use pliers to strip some of the wire (not more than ¼ inch) on either side.
- Connect both the ends of the wire to the relay housing in your refrigerator using an electrical tape. This will completely bypass the missing relay and complete the circuit.
- Put the relay system metal box and the cover plate back in their places.
Once you have bypassed the start relay on your refrigerator, you need to follow some pivotal steps to make sure everything works smoothly until a professional comes to fix it.
Plug the refrigerator back and turn on the power. Now, you need to monitor it for three to four hours to make sure the compressor is functioning properly.
If your compressor makes a clicking sound or a humming sound, it means that the relay itself was defective.
Don’t leave the appliance in a state of relay bypass for too long as it may overload the compressor. As I mentioned earlier, this is just a quick temporary fix. Contact a technician to help you repair the refrigerator relay as soon as possible and get it fully functional.
