How to Fix / Troubleshooting
Safety: Unplug the unit before opening any panels; risk of electric shock otherwise.
- Verify outlet: Test the outlet with another appliance to confirm power.
- Inspect power cord: Check for cuts, kinks, or burn marks. Replace the power cord if damaged.
- Access control board: Remove the rear or top panel to reach the main control board. Look for an onboard fuse and check continuity with a multimeter. Replace the fuse only with the same type and rating if blown, and investigate why it failed.
- Check connectors: Ensure the incoming power harness is firmly connected to the control board.
- Replace control board: If power is present at the board input but the display remains dead, replace the main control board.
