    What to do if my Hanbell Compressor's motor thermistor trips suddenly?
    • R
      Robert McclureAug 4, 2025
      If your Hanbell Compressor's motor thermistor or sensor suddenly trips, it could be due to several reasons. The suction pressure might be low, leading to a low refrigerant flow rate; in this case, consider installing liquid injection to the motor coil. Another cause could be a refrigerant shortage, which can be resolved by charging refrigerant. A clogged suction filter can also cause this issue, so cleaning the filter is recommended. High suction temperature may be the reason, so install liquid injection to motor coil. High suction superheat, adjust the superheat less than 10°K. Finally, an unstable electricity system or failure could be the culprit, requiring a check of the electricity power supply.

      If your Hanbell Compressor is unable to load, there are several potential causes. One reason could be low ambient temperature or high oil viscosity; in this case, turn on the oil heater before starting the compressor. Another possibility is a clogged capillary, which would require cleaning or replacement. The modulation solenoid valve might be clogged, or its coil could be burnt, necessitating cleaning/purging of the valve core or replacement of the coil. An internal built-in oil line could also be clogged, so check and clean the compressor oil circuit. If the piston is stuck, change the piston or piston ring. Also, a clogged oil filter cartridge could be the reason, so clean the oil filter (replace if needed). Finally, if the high-low pressure differential is too small, consider installin...
