Condensation forming on exterior cabinet or around door seals

How to Fix / Troubleshooting

Safety first: Unplug the refrigerator before accessing any heater wiring.

Step 1 – Reduce humidity and openings:

Use kitchen ventilation when cooking.
Limit door opening duration.

Step 2 – Check door seals:

Inspect and repair/replace gaskets as described in the frost buildup scenario.

Step 3 – Mullion heater (if equipped):

Some models have a heater in the door frame; if condensation is severe and persistent, the heater circuit may have failed.
This typically requires professional diagnosis and possible replacement of the heater or control board.
