Possible Causes
Defective defrost heater, Failed defrost sensor or thermostat, Door gasket leak allowing moist air in, Door frequently left ajar
How to Fix / Troubleshooting
Safety: Unplug the wine cooler. Place towels to catch meltwater. Do not use sharp tools to remove ice.
- Manual defrost: Leave the door open and allow all ice to melt completely. This may take several hours.
- Inspect door gasket: Check for gaps or damage. Replace the Grundig door gasket if it does not seal tightly.
- Check defrost components: Remove the interior rear panel and test the Grundig defrost heater and defrost NTC sensor for continuity and correct resistance.
- Replace faulty parts: Install new defrost components if they test bad. Ensure the sensor is properly clipped to the evaporator.
- Monitor usage: Avoid frequent long door openings, which introduce moisture and accelerate frost buildup.
