The overload relay is a protection device used in the compressor circuit on your refrigerator. Power is applied to the compressor motor windings through the overload device, and the relay is used to add the start winding in the circuit until the compressor is at running speed.
Thereof, How do you know if your refrigerator relay is bad?
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.

Subsequently, question is, What is the function of relay in fridge? The overload relay is a protection device used in the compressor circuit on your refrigerator. Power is applied to the compressor motor windings through the overload device, and the relay is used to add the start winding in the circuit until the compressor is at running speed.

What is a PTC relay?
A PTC relay is a device that is used when the fridge compressor motor starts. A fridge with a faulty PTC relay cannot start or continuously clicks on and off unable to start.

What does a start relay do on a refrigerator?
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.
What does a start relay do?
Their main function is to assist in starting the motor. Knowing the sequence of operation for this type of starting relay can help you diagnose, confirm, or rule out certain service problems. Potential starting relays consist of a high resistance coil and a set of normally closed contacts.
How do you bypass the overload relay 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 do you test a relay?
The only tool required to check a relay is a multimeter. With the relay removed from the fuse box, the multimeter set to measure DC voltage and the switch in the cab activated, first check to see if there are 12 volts at the 85 position in the fuse box where the relay plugs in (or wherever the relay is located).

What is PTC relay in refrigerator?
A PTC relay is a device that is used when the fridge compressor motor starts. A fridge with a faulty PTC relay cannot start or continuously clicks on and off unable to start.
How do you test a starter relay with a multimeter?
Set your multimeter to be on the Ohms scale. Place one probe on the lead on the ignition circuit terminal and the other on the ground lead. The reading should be less than 5 Ohms. If it’s more than that, the starter relay is faulty and needs to be replaced.

What is a PTC relay in a car?
The PTC relays are used by the A/C auto amp. to turn ON one, two, or three of the PTC heating elements. Each relay provides current to a specific section/element of the PTC heater. The A/C auto amp will turn ON one, two, or all three PTC relays depending on the heating requirements as determined by sensor inputs.
