The relay can be damaged if the jammed movable contacts that closes the power supply circuit starting winding. In this case, the motor can run for 5-10 seconds and shut down or run does not happen at all.

No less common cause of failure in the thermal relay is to weaken the spring plate. Turning off the power of the compressor in this case is true even if the current consumption in the normal amount. Thus the thermal protection is triggered.

Quite often due to poor material is heated spiral, it may burn out. In this case, the problem must be sought in the compressor.

After verification of the control circuit, it is necessary to examine the relay. First cover removed, which may be aluminum or snap rivets located at the base.

Almost all refrigerators have puskozaschitnoy relay this scheme. Among the faults within the relay, often burns contact pair may be jammed core, the spring is broken or rod.

To correct such failure, need to pull the bobbin ... Read more »

Types of relays in refrigerators

After the electric motor got the necessary momentum launcher coil must be switched off. For this purpose puskozaschitnoy relay that breaks the circuit when it reaches a certain temperature sensitive element. It may have two or three exits. In the first case - a phase 110 V - earth, and in the second case - Start winding - operating winding - land. Starting relay works for several schemes.

Option 1 - "Pills"

The basis of this work item is a material that expands when heated. Upon reaching a certain temperature within the "pill" contact opens and stays connected only coil. To maintain such a regime on the working coil used reactor, a heated element. In case of failure of the relay inside there is the sound of the spilled material.

2. Option - induction switch

The basis of the work of such a mechanism are electromagnets, in which at the core is started when the current passes through the coil o ... Read more »
