How to Fix / Troubleshooting
Safety: Ensure the outlet is properly grounded. Do not bypass fuses with wire or foil.
Steps:
- Check outlet: Plug a lamp or other appliance into the same outlet to confirm power. Reset any tripped breakers or GFCI outlets.
- Inspect power cord: Look for cuts, burns, or kinks. If damaged, replace the cord set or have it replaced by a technician.
- Access control board: Remove the rear panel to locate the main control board. Look for an onboard fuse; test it with a multimeter and replace with the same rating if blown.
- Check board for damage: Inspect for burnt components or bulging capacitors. If present, replace the main control board with a Whynter-compatible part.
If the unit still does not power on after these checks, professional diagnosis is recommended to avoid electrical hazards.
