Possible Causes

Faulty power level control on main board, Stuck relay causing full power, Defective humidity or temperature sensor (on sensor-cook models), Incorrect power calibration

How to Fix / Troubleshooting

Safety: Monitor closely to avoid fire risk.

User steps:

  • Test at lower power levels (e.g., 50%) to see if control responds.
  • Try different auto programs; if all modes overcook, control regulation is suspect.

Because this involves control electronics and sensors, a technician should test the power output and sensor feedback. Continued use may pose a fire hazard if power cannot be regulated correctly.
