How to Fix / Troubleshooting
Safety first: Disconnect the unit before inspecting the cord or internal wiring.
Steps to check:
- Verify outlet: Plug a lamp or other device into the same outlet to confirm it has power.
- Check breaker/GFCI: Reset any tripped breakers or GFCI outlets.
- Inspect power cord: Look for cuts, burns, or kinks. If damaged, replace the cord set.
- Check internal connections: Remove the rear or bottom panel and verify the cord connections to the control board are secure.
- Board power supply: If the outlet and cord are good but the unit is dead, the board’s power supply section may have failed and the main control board will need replacement.
