How to Fix / Troubleshooting

Some Frigidaire Gallery models have an energy saver or humidity control switch for the door mullion heater. Turn humidity control ON in humid environments.

Step 2: Inspect gaskets

Ensure door gaskets seal properly to minimize moist air infiltration.

Step 3: Mullion heater check

If condensation persists along the vertical mullion between French doors, the heater strip may have failed.
Replacement of the mullion heater or door assembly may be required.
