Condensation or moisture forming on the inside of glass doors or on interior walls.

Safety first: Moisture can make floors slippery; wipe up water promptly.

Step 1 – Check door gaskets

• Inspect door gaskets for gaps or damage and correct as needed.

Step 2 – Adjust usage

• Reduce the frequency and duration of door openings, especially in very humid weather.

Step 3 – Verify settings

• Ensure refrigerator and freezer are set to recommended temperatures (typically ~38°F and 0°F).

Step 4 – Heater circuit check

• If condensation forms on mullion or frame areas, the anti‑sweat heater circuit may be off or failed; a technician can test and replace the heater or control board if necessary.
