If your Friedrich Heat Pump activates room freeze protection, ensure the room is properly insulated. Check the T8 sensor and replace it if necessary. You may also need to replace the Wall Controller.
Why is the humidity sensor (T12) open or shorted in my Friedrich VRP12K Heat Pump?
The humidity sensor (T12) in your Friedrich Heat Pump might be open or shorted because the wall controller isn't properly connected to the FMC, there's an issue with the sensor itself, or the sensor is genuinely open or shorted. To resolve this, check the sensor and correct as needed. Also, verify the wall controller connection; if the problem persists, consider replacing it.
What to do if Ambient Indoor Air sensor (T8) is open or shorted in Friedrich VRP12K?
If the Ambient Indoor Air sensor (T8) in your Friedrich Heat Pump is open or shorted, it could be due to a faulty sensor or defective contact between electrical connectors, or the sensor is not properly connected to the FMC. Try disconnecting and reconnecting the sensor at the FMC. Check the sensor and correct as needed. If problems persist, consider replacing the FMC board.
