A PTC relay uses a positive temperature coefficient thermistor to remove the start winding and/or start capacitor from the circuit. A PTC thermistor is basically a resistor whose resistance increases on an increase in temperature. The circuit is wired so that the PTC thermistor is wired in series with the start winding of the motor (Fig. 1).

A PTC (Positive Temperature Coefficient) relay is a starting device for fridge compressors. It is responsible for powering the start winding for a brief moment to help start up the fridge compressor motor. If your fridge cannot start there is a high probability that the PTC relay is defective. This article presents how to test them to determine whether they need replacing.

If the reading on the multimeter is between 0 and 1 ohms, the relay is in good working condition. If the reading exceeds 1 ohm, replace the PTC relay. In other words, the relay should read O.L or 0 to 1 ohm. Before testing the relay, clean the device and all its sports to remove dust. Dust may interfere with the resistance reading, throwing it off.

This video provides step-by-step repair instructions for replacing the PTC relay on a GE refrigerator. The PTC relay sends power to the start winding to star.
Threephase asynchronous motor PTC protection circuits under Motor
The wiring diagram for a refrigerator PTC relay typically consists of several components, including the relay itself, the compressor motor, the start capacitor, and the overload protector. Each of these components has specific connections that need to be made to ensure proper functioning. It is essential to carefully follow the manufacturer's.
PTC Heater Relay
Set your multimeter to read resistance in ohms (ฮฉ) so you can easily test the PTC relay. Plug the end of the red probe into the positive (+) terminal and the black probe into the negative (-) terminal on the bottom of the multimeter so you can use them. [8] You can buy a multimeter from a hardware store or online. 3.

With the start capacitor we connect the ptc relay thermistor in series, which eliminates the start capacitor in the circuit. In many relay PTC compressor has a connection point for the operating capacitor and connect the capacitor in parallel with the relay, which helps better performance and compressor. ptc relay working principle, ptc relay.

The circuit diagram below shows an example of an inrush current limiter (ICL) circuit, in which a PTC thermistor and a thyristor (or a mechanical relay) are used in combination. When the power switch is closed and the charging process starts, the uncharged capacitor is like a short circuit and therefore draws a very high inrush current.

Temperature protection using PTC and LM393 Electronic Circuit
The PTC (positive temperature coefficient) relay is directly connected in series with the secondary winding (start winding) and in parallel with the main winding of the motor. When AC 220V is applied to the two windings, a phase difference will be generated due to phase separation, thus forming an elliptical rotating magnetic field and generating a starting torque to drive the normal operation.
