Moisture, frost, or condensation appears inside the compartment or on the exterior surfaces of the unit. Internal moisture is usually caused by door/drawer issues or high humidity. External moisture may additionally indicate a missing or faulty dual-unit install heater.
| Possible Cause | How to Fix |
|---|---|
| Door/drawer not closing properly | Check for obstructions; repair/replace gasket; fix hinge binding |
| Frequent door openings | Instruct customer to minimize openings |
| High relative humidity | Instruct customer; this can be normal in humid climates |
| Dual unit install package not used or faulty (external moisture) | Check for install package. Verify 115V at wire harness by compressor. Check heater resistance: tall unit = 263-313 ohms, base unit = 540-640 ohms. Replace if out of range. |
