Preheat or cooking time completes but food is undercooked compared to previous use with same settings.

Safety first: Unplug before internal sensor checks.

• Step 1 – Verify with thermometer: Place an oven thermometer in the basket and run a cycle to compare actual temperature to the set value.
• Step 2 – Inspect sensor placement: Ensure the NTC sensor is correctly clipped near the chamber wall and not hanging in a cooler area.
• Step 3 – Replace sensor: If readings are consistently low, replace the cabinet NTC sensor.
• Step 4 – Consider heater wear: If the sensor is accurate but heat is still low, the heater may be weakening; replace the heating element assembly.
