It is definitely not normal for the refrigerator motor to turn on and then turn off. After all, in this case, the temperature in the refrigerator is much higher than necessary to preserve the food.
If your fridge does not want to work in normal mode either – firstly, check the voltage in the network and it is quite possible that the refrigerator stops the compressor because of voltage jumps. Frankly speaking only new models of fridges behave in such way more often. If the old units in your kitchen or the voltage is all right, it means that there is some kind of malfunction.
Possible reasons why your fridge stopped working and then started again:
- Motor-compressor malfunctions
Winding breakage, inter-turn short circuit or motor does not work. The defective motor starts to run, gets very hot, and to protect the compressor from overloading, the starting and safety relay is activated and the motor shuts down.
Signs:
Fridge goes on and off after a few seconds. A clicking sound is heard and the refrigerator motor is very hot.
How to fix:
If motor-compressor is out of order, it cannot be repaired and must be replaced.
- Faulty control board
This can be the reason why the compressor runs for a short time and shuts down. In this case it is the control board that gives the command for premature shutdown.
Signs:
The refrigerator is turning on and off. The operating intervals may be different in duration.
How to fix:
Control board needs to be replaced.
- Compressor motor relay is defective
Normally, this relay is designed to control the motor start and protect it from overloads. It is activated and deactivated by a bimetallic plate that closes and opens. The plate is heated by the current flowing through it, the plate bends with a characteristic click, the contact opens and the motor shuts off. Because of a break in the relay and changes in the conductivity of the plate, the process is broken and the motor shuts off almost immediately.
Signs:
Fridge turns on and off after a few seconds. A clicking sound is heard.
How to fix:
Relay needs to be replaced.
Refrigerators Are One of the Longest Lasting Appliances
Typical fridge can last up tо 13 years, and even longer when prоperly maintained—talk about a return оn your money. Yоu may go thrоugh several TVs in that timeframe, as a TV’s lifespan averages abоut 4 years.Interner Research
On many forums on the net, you can read the following advice: if the refrigerator shuts down at once – try to replace the relay. If the operation cycle is normal, then the problem was in it. If not, then the problem is in the motor or the board.
On the one hand, indeed, changing the relay is a rather simple operation, if you compare it with the flashing of the board or replacing the motor. However, before you start fixing it by yourself, think about whether you can handle this operation. Do you know which relay is necessary for your fridge model and where to buy it? And what to do if it turns out that it is not the relay at all? As a result, you will lose money, nerves and time. The latter, if your fridge is full of food, is it worth it?
