Why is my Bosch Heat Pump not shifting into cooling?
- E
  epageAug 22, 2025
  If your Bosch Heat Pump isn't shifting into cooling mode, check that the reversing valve solenoid is receiving 24 VAC. If it is, check the resistance of the solenoid; an open circuit may indicate a burned out solenoid. Also, check that the reversing valve thermostat wire is connected to the 'O' terminal of the thermostat and check for a contact closure between 'O' and 'R'. Finally, check that the wires from the thermostat to the unit are securely connected and that the wires from the electrical box to the reversing valve are connected.

  Matthew ThompsonAug 23, 2025
  If you're experiencing objectionable noise levels from your Bosch Heat Pump, ensure the duct work and grilles are properly sized for unit air flow. If the fan speed setting is too high, consult the blower performance table and reduce fan speed if possible. To address structure borne noise, mount the unit on a vibration pad. Also, install the unit in accordance with the provided instructions and adjust the unit location to prevent it from touching the structure.

  If your Bosch Heat Pump's compressor isn't running but the fan is, it could be due to a freeze fault in the water coil caused by no or low water flow. Check the water valves and/or pumps to ensure they are operating correctly. Also, check the water coil for any blockages.

  Michelle FieldsAug 29, 2025
  If your Bosch Heat Pump's compressor isn't running but the fan is, it could be due to a high-pressure fault caused by a fouled or scaled water coil. Check for proper flow rate and water temperature, especially looking for a low water side temperature rise during cooling.

What to do if my Bosch LV060 Heat Pump compressor isn't running but the fan is on and I suspect an overloaded control circuit?
- E
  Eric BassSep 2, 2025
  If the compressor of your Bosch Heat Pump is not working, but the fan is running, it might be due to a brown-out fault caused by an overloaded control circuit. Check the control voltage; if it's below 18V, inspect the accessories connected to the unit and ensure they don't exceed the VA draw.
