What to do if my Bosch Heat Pump compressor isn't running but the fan is, and I suspect airflow issues?
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 no or low airflow. Check the fan motor to ensure it is operating correctly.
How to troubleshoot a Bosch Heat Pump with no compressor operation but running fan, possibly due to a fouled water coil?
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.
Why is my Bosch LV030 Heat Pump compressor not running but the fan is, possibly due to high water temperature?
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 high water temperature. Check the water temperature to ensure it is within the appropriate range.
What to do if the compressor of my Bosch LV030 doesn't work but the fan runs and there is a freeze fault?
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.
What to do if my Bosch LV030 Heat Pump compressor isn't running and the fan is on, but I suspect low refrigerant?
If your Bosch Heat Pump's compressor isn't running but the fan is, it could be due to a low-pressure fault caused by low refrigerant. Check the refrigerant pressure with a gauge set.
Why is my Bosch Heat Pump not shifting into cooling?
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.
