What is the function of relay in refrigerator?

It goes on and off during the cooling cycle, maintaining the ideal temperature inside the cabinet. For the compressor to be connected, the start relay is required, it is responsible for supplying energy to the unit. The relay is in the on/off operating command.

How do I know if my compressor relay is bad?

Signs of a Bad or Failing AC Compressor Relay

  1. Inconsistent cooling. The AC compressor is powered by the relay.
  2. AC compressor is not turning on. One of the most obvious signs that the AC relay may have a problem is that the compressor is not coming on at all.
  3. No cold air.

How do you bypass a refrigerator relay?

Use a flathead screwdriver to press down on the space between the relay and its casing. Then, press on the relay itself and pull it out to remove it from the refrigerator. Slide the wire from the relay so it’s accessible.

How do you check a relay?

Here’s How To Test a Relay

  1. Locate the relay you need to test.
  2. The quickest and easiest way to test a relay is to swap it out with a known good replacement.
  3. Grab a multimeter and set it to Ohms.
  4. Leave the multimeter on ohms or continuity.
  5. Energize the electromagnet coil with a 9-12V battery across the pins.

What causes a refrigerator relay to go bad?

Electrical Surge Refrigerator relays protect the fridge from electrical damage. An electrical surge can be one reason that a relay will fail and overload. When the resistance of the wire impedes the electrical current, the wires can become hot and begin to melt. An electrical surge can cause this to occur.

How does a refrigerator start relay work?

A refrigerator start relay is a device that jump-starts the compressor inside the refrigerator. If the refrigerator start relay is burned out, then the compressor may not work and the interior will not freeze.

Why do I need a relay on my refridgerator?

The compressor turns on and off periodically for an effective cooling process, and for this very reason, a relay is used to assist the compressor while functioning. Relay is an electrical switch that tells your compressor to turn on or off depending on the temperature inside the unit. If the relay stops working, the compressor will also stop.

How to change the start relay of the refrigerator compressor?

How to change the start relay As already mentioned, there are different types of relays. When it is necessary to make a change, do not try to improvise or make use of not recommended solutions. This can cause problems, such as the burn-out of the compressor.

How do you remove a PTC relay from a refrigerator?

The PTC relay will look like a small black box attached to the side of your compressor with 2-3 wires running to it. Grip the ends of the wires with a pair of needle-nose pliers and carefully pull them off the prongs of the relay. Disconnect each wire from place so you’re able to remove the relay.

What does a positive temperature coefficeint relay do?

A positive temperature coefficeint relay, also known as a PTC or a start relay, starts the compressor inside of your fridge. The compressor is what creates the cold air that keeps your refrigerator cold. So, if your fridge stops making cold air, there could be a problem with the PTC relay.
