How to Fix / Troubleshooting
Safety: Always unplug the unit before opening any panels. Do not operate the unit on damaged wiring or outlets.
- Check power source: Verify the outlet voltage with a multimeter (should be around 120V AC in North America). Avoid using long extension cords or power strips.
- Inspect power cord: Look for cuts, burns, or kinks in the Comfee power cord. Replace the power cord set if damaged.
- Internal inspection: Remove the rear or side panel and inspect the main control board for burnt components or discoloration, especially around the power supply section.
- Secure connections: Tighten any loose spade connectors on the compressor, fan, and line input. Ensure the ground wire is firmly attached.
- Board replacement: If the supply voltage is correct and wiring is sound but E8 persists, replace the main control board. If the compressor is noisy or very hot, a technician should evaluate the compressor itself.
