How to Fix / Troubleshooting
Safety: Unplug the unit before defrosting or accessing internal components.
Steps:
- 1. Manual defrost: Turn off and unplug the cooler. Open the door and place towels to catch water. Allow all ice to melt naturally; do not use sharp tools or heat guns.
- 2. Inspect door gasket: After defrosting, check the gasket for gaps or damage. Replace the La Sommeliere door gasket if it does not seal evenly.
- 3. Check defrost components: On models with automatic defrost, remove the inner rear panel and test the defrost heater and defrost sensor as described in the E4 scenario.
- 4. Ensure air circulation: Do not block air vents with bottles or shelves. Make sure the evaporator fan is operating correctly.
- 5. Reassemble and monitor: After repairs, monitor for several weeks. If heavy frost returns quickly, have a technician check the defrost control logic and sealed system.
