Possible Causes

Failed evaporator fan in warm zone, Air damper stuck closed between zones, Separate sensor failure in affected zone, Control board not energizing zone components

How to Fix / Troubleshooting

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

Steps to diagnose:

  • 1. Compare zones: Verify setpoints and actual temperatures in both zones with thermometers.
  • 2. Listen for fans: With power on (initial check), listen for fan operation in both zones. Then unplug before opening panels.
  • 3. Access warm zone evaporator: Remove shelves and rear panel in the affected zone to inspect the fan and evaporator.
  • 4. Check fan and damper: Ensure the fan spins freely and the air damper (if present) is not stuck closed. Replace the fan motor if it does not run.
  • 5. Test zone sensor: Measure resistance of the temperature sensor for the warm zone and replace if out of spec.
