Possible Causes

Air damper between zones stuck open, Control board not regulating zones separately, Sensor wiring crossed or misconnected, Failed zone sensor

How to Fix / Troubleshooting

Safety first: Unplug the unit before accessing interior panels or the control board.

Steps to correct:

  • 1. Verify configuration: Confirm the model is truly dual-zone and not a single-zone with two displays.
  • 2. Inspect air damper: Access the partition between zones and check the damper mechanism. Ensure it moves freely and is not stuck open.
  • 3. Check sensors: Verify each zone has its own sensor and that wiring is correctly connected to the control board.
  • 4. Control board evaluation: If dampers and sensors are correct, the main control board may have lost independent zone control and require replacement.
