Possible Causes
Failed main control board outputs, disconnected fan and heater wiring, internal safety cutoff open
How to Fix / Troubleshooting
Safety first: Unplug before opening the unit.
- Reset: Cancel the program, unplug for 5 minutes, then reprogram and start again to rule out a software glitch.
- Check safety interlocks: Ensure basket and lid switches are functioning; a misread switch can prevent outputs while allowing the timer to run.
- Internal wiring: Inspect connections from the main control board to the fan motor and heating element. Reseat any loose connectors.
- Board diagnosis: If wiring and safety switches are good, the control board's output drivers may have failed. Replace the main control board.
