- C
  Cheryl HughesAug 13, 2025
  If your Zamil Air Conditioner compressor hums but trips on the overload protector, the following could be the cause: * **Improperly wired:** Check the wiring against the diagram. * **Low voltage to unit:** Determine the reason and correct it. * **Starting capacitor defective:** Determine the reason and replace it. * **Relay failing to close:** Determine the reason and correct it; replace if necessary. * **Compressor motor has a winding open or shorted:** Replace the compressor. * **Internal mechanical trouble in compressor:** Replace the compressor. * **Liquid refrigerant in compressor:** Check the crank case heater. * **High discharge pressure:** Unequilized pressure in the system.
