Refrigerators have been necessary for people's daily life, and there are probably some problems with your refrigerators after a long time of use. So this article will let you know one of the causes of the failing refrigerator - a bad start relay of the compressor.

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 of the motor. After that, because the PTC relay is under a high resistance state, the starting circuit is nearly disconnected, and only the running winding drives the motor to run.

The refrigerator malfunction may be caused by the refrigeration system or the electrical system. When judging the compressor fault, you should first confirm whether the electrical system is working normally. You should check if the power plug is in contact with the power switch, if the fuse is open, if the power connection is normal, and the power voltage. You should also inspect where the thermostat is placed, whether the temperature sensor leaks, whether the temperature adjustment is appropriate, and if the induction action is working.

1. Main Circuit Wiring 1.1 Open the cover by squeezing the grooves on both sides of the VFD(variable frequency drive), remove the wire baffle, connect the terminals R, S, T to the power, connect the terminals U, V, W to the motor, and connect the earth wire at the ground symbol. 1.2 Connect the yellow, green and red power cables to the R, S and T in sequence.

The traditional method of starting an AC induction motor "across the line" results in full voltage, current, and torque being applied immediately when the motor is started, and likewise, being removed immediately when the motor is stopped. While this is the most simple starting method, the high inrush current (often 6 to 7 times the motor's rated current) and peak starting torque can damage the motor, driven equipment, and product. Across the line starting also causes high peak power demand, which can trigger peak demand fees from the utility company. A soft starter can eliminate these problems by gradually increasing voltage to the motor terminals during startup, providing a controlled ramp-up to full speed. This lowers inrush current and controls starting torque, reducing mechanical shocks to the system and the product.

According to public statistics, since 2010, the 142-year-old Japanese technology giant has started to move from profit to loss. Due to the impact of nuclear power and other businesses, Toshiba has a huge debt of US$6.1 billion (about 41 billion yuan). It was forced to start the road of selling debts.
