What is PTC starter in refrigerator?

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.

How do you bypass a capacitor on a refrigerator?

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 does a PTC work?

PTC devices are designed with a specific maximum temperature. This design makes the circuit self-regulating in that resistance rises as the temperature reaches the maximum temperature and shuts off the current in the circuit. Ohm law looks more like this, along with the temperature and resistance graph.

How do I reset my refrigerator compressor?

4 steps to reset a refrigerator compressor

  1. Unplug your refrigerator.
  2. Turn off the refrigerator and freezer from the control panel.
  3. Reset your freezer and fridge temperature settings.
  4. Wait for the refrigerator temperature to stabilize.

What is the meaning of PTC relay?

A PTC relay means positive temperature coefficient is a starting device for refrigerator compressors. It is responsible for providing power to the start winding for a brief moment to help start the cooling compressor motor.

How do you know if your refrigerator relay is bad?

The Shake and Rattle Test Unplug the start relay from the compressor and give it a shake. If you can hear rattling on the inside of the start relay, then the part is bad and will have to be replaced. If it’s not rattling and appears to be in good condition, you may have a problem with the actual compressor.

Why mini fridge stopped working?

Some of the many reasons a mini fridge may not be running properly could be due to an issue in the sealed system, a failed compressor, failed evaporator fan motor, condenser fan motor, or a thermostat. Other issues could range from evaporator coils, start relays, the control board, or a restriction in the drier filter.
