Why does my Bosch Heat Pump outdoor unit start and stop continuously?
- JJocelyn CastroAug 7, 2025
If your Bosch Heat Pump's outdoor or indoor unit starts and stops continuously, there might be insufficient or too much refrigerant in the system. Check the tightness of the pipes, reseal if needed, and refill the refrigerant or remove refrigerant with a refrigerant recovery unit. Also, moisture or impurities in the refrigerant circuit could be the cause, so evacuate the refrigerant circuit and fill it with new refrigerant. High voltage fluctuations can also cause this issue, so install a voltage regulator. Finally, a defective compressor could be the problem, requiring a compressor replacement.
