1. The terminal post of the thermostat is stuck and falls off
Cause the compressor not to start, the dynamic and static contacts of the thermostat can not be disconnected, so that the compressor does not run, the thermostat contacts can not be disconnected, so that the motor of the refrigerator compressor does not stop, in addition to the balance elastic force is too weak, it can also be caused by the accumulation of words on the contact and adhesion. In this case, the power supply can be cut off, the thermostat knob can be rotated repeatedly from "stop" to the coldest position, and then the power supply will be connected, and the spin will return to normal, indicating that the fault has been eliminated.
2. The compression caused by the broken circuit of the thermostat will not start
The main reason for the disconnection of the thermostat is that the wiring falls off to the clip or the thermostat leakage of the thermostat in the temperature bag. The temperature sensor leaks, the pressure in the temperature sensing chamber is reduced to atmospheric pressure, and the lever connected to the moving contact is only pulled by the balance spring, so the dynamic and static contacts cannot be closed, and the thermostat is in an open state, and the compressor cannot be started. In order to further check, hold the temperature sensor tube with your hand and add a cylinder to it slightly, if the contact is still not closed, it means that the temperature sensor is indeed leaking.
3. The thermostat temperature sensing tube leaves the surface of the evaporator, causing non-stop
The temperature control of the thermostat is too low, which causes hunger. It should be noted that whether it is a new or repaired thermostat, it must be debugged after installing the refrigerator to keep the box temperature within the rated range. In general, the temperature of the refrigerator is 2 degrees Celsius, and if the thermostat contacts are closed at more than 10 degrees Celsius, it needs to be adjusted. When adjusting the operation, you should first check whether the temperature sensor tube is installed.

Analysis of common fault causes of RKC temperature controller
1. The power indication is normal, but the temperature controller has no screen display. Most of this fault is caused by the heating of the voltage regulator element (7805 or 7812) on the thermostat during long-term use, which causes the solder joint to show a breakpoint, and sometimes it is caused by the phenomenon of virtual soldering at the factory.
2. Temperature controller ...
