Unit powers on but will not start cooking when Start button is pressed.

Safety first: Unplug the unit before mechanical or electrical checks.

• Confirm basket position: Remove and firmly reinsert the basket drawer. Ensure it is flush with the front panel.
• Test other buttons: If other buttons respond but Start does not, the Start key on the touch panel may be faulty. Replace the touch control panel assembly.
• Check interlock switch: Verify the basket interlock switch operates correctly with a multimeter as described in interlock-related entries.
• Control reset: Unplug for 10 minutes to reset the control. If the issue persists with a good panel and switch, replace the main control PCB.
