What is the PTC relay for?

PTC relay is a specific starting device, which works for the compressor of the refrigerators. The principle function of the PTC relay is to provide power to the start winding for a brief period to help to trigger the motor of the cooling compressor.

Can you bypass a PTC relay?

You’ll need to remove the metal connecter attaching it to the relay system first and then use pliers to strip some of the wire (no more than ΒΌ inch) on either side. Using electrical tape, connect both ends of the wire back to the relay housing so it completely bypasses the missing relay and closes the circuit.

How do you test a PTC relay?

Put the probes of a multimeter on the left and right prongs of the compressor. Locate the 3 prongs that the PTC relay plugs into on the side of your compressor. Put one probe on the prong that’s furthest to the left and the other probe on the prong on the right to take a resistance reading.

What is PTC relay of compressor?

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?

Signs and Symptoms of a Bad Start Relay on a Refrigerator

  1. Refrigerator Not Cooling. The most obvious sign that your start relay isn’t working is the lack of cooling caused when the compressor never starts up.
  2. Clicking Relay Noise.
  3. The Shake and Rattle Test.
  4. Replacing the Start Relay.

What is a start thermistor?

PTC Thermistor Motor Starter is PTC Thermistor used for delaying the switch-off of the motor starter auxiliary winding (after the motor has accelerated) to protect the winding from damage.

What is an overload protector?

The overload protector sits near the condenser by the current start relay and ensures the condenser does not overheat while working. If the overload protector senses that the compressor is approaching failure from overheating, it will temporarily shut the compressor down to allow it to cool.
