KitchenAid · Microwave Combination Oven
The oven's main temperature sensor is either disconnected (open) or faulty (shorted). This prevents the oven from accurately reading and controlling the internal temperature.
Click steps to track your progress.
Unplug the oven or disconnect its power at the circuit breaker for at least 10 seconds.
Plug the oven back in or restore power.
Check the oven display to see if it shows the correct ambient room temperature (approx. 77°F/25°C).
If the temperature reading is incorrect or the error persists, contact customer service for assistance.
