Possible Causes
Failed zone divider insulation, Air damper stuck open, Thermistors cross-wired or failed, Control board not regulating zones separately
How to Fix / Troubleshooting
Safety: Unplug the unit before removing interior panels.
- Verify setpoints: Confirm that the two zones are set to different temperatures on the display.
- Inspect divider and seals: Check the physical divider between zones and any gaskets or seals for damage that would allow free air mixing.
- Check dampers: If the model uses dampers, ensure they are not stuck open, allowing full air exchange between zones.
- Test thermistors: Verify each zone's thermistor reads correctly. Replace any that are out of spec.
- Control board replacement: If mechanical separation is intact and sensors are good, the main control board may have lost independent control of the zones and should be replaced.
