What to do if my Bosch LV018 Heat Pump compressor isn't running but the fan is on and I suspect an overloaded control circuit?
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.
Why is my Bosch Heat Pump compressor not running but the fan is, possibly due to low airflow?
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 no or low airflow. Check the fan motor to ensure it is operating correctly.
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 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 LV018 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 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.
How to reduce objectionable noise levels from my Bosch Heat Pump?
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.
