Using metallic ware and
allowing it to touch the oven
wall.
Food temperature is too low.
Low AC input voltage.
Troubleshooting
1. Check outlet for proper voltage and grounding before diagnosing.
2. Be careful of the high voltage circuit.
3. REMEMBER: Discharge the high voltage capacitor.
4. When making component tests, remove power, disconnect one lead wire from component and check
continuity; otherwise, electrical shock, false reading, or meter damage may occur.
5. Do not touch any part of the circuit on the PCB since static electric discharge may damage this control
panel. Always touch ground before working on the control panel to discharge any static charge built
up in your body.
