Possible Causes
Low refrigerant charge due to micro-leak, Partially blocked capillary tube, Weak compressor, Dirty condenser coil reducing heat rejection
How to Fix / Troubleshooting
Safety: Do not attempt to open the sealed refrigeration system. Only certified technicians may handle refrigerant.
User-level checks:
- 1. Verify load and usage: Avoid loading many warm bottles at once. Allow 24 hours for temperature to stabilize after loading.
- 2. Check door seal: Inspect the gasket for gaps or damage. Close the door on a sheet of paper; if it pulls out easily, the seal may be weak. Replace if necessary.
- 3. Clean condenser: Unplug the unit, remove the rear panel, and gently clean dust from the condenser coil.
- 4. Ambient temperature: Ensure the cooler is installed within the specified ambient range. Very hot rooms reduce performance.
- 5. Feel temperature gradient: Carefully touch the condenser and compressor after running for 15–20 minutes (they should be warm/hot). If they are running but the cabinet remains warm, a sealed system issue is likely and requires professional service.
