Condensation or fogging on a True Residential glass door usually means the anti-condensation heater has failed or the door gasket is no longer sealing. Warm, humid room air is reaching the cold glass.
The fix is to replace the heater or gasket and confirm the door seals tightly so the glass stays clear and the interior holds humidity.
Symptom and Error Guide
| Code / Symptom | What It Means | What We Do |
|---|---|---|
Glass fogging | Anti-condensation heater failed | Replace the heater |
Condensation at the seal | Worn door gasket | Replace the gasket, confirm the seal |
Door not sealing | Sprung hinge or gasket | Adjust the hinge, replace the gasket |
What We Check
- Refrigerator or wine column running warm
- Glass door fogging or condensation on the interior
- Wine zone drifting off its set temperature
- Frost or ice building inside the cabinet
Keeping the door gasket clean and checking that the door closes flush prevents fogging. A gasket that has hardened or torn should be replaced before it affects temperature.
