What to do if the electromagnetic coupling of the Belarus 920.4 compressor does not operate?
- DDerrick PrestonAug 2, 2025
If the electromagnetic coupling of the Belarus Tractor compressor isn't working, it could be due to electrical equipment failure or a coolant leak. Use a tester or multimeter to check the pressure sensor unit and the electric circuit connections from the compressor coupling to the air conditioner control panel. The sensor unit terminals (red and pink wires) must create a continuous circuit. Also, look for refrigerating fluid leak spots. Note that leak detection, hose replacement, and component repairs should be done by trained personnel with specialized equipment.
