Clean the oven cavity: Remove any accumulated food debris or grease from the oven cavity, as it can affect heat distribution. Use a non-abrasive cleaner and follow the manufacturer's instructions.
Calibrate the temperature: If you suspect the oven temperature is inaccurate, use an oven thermometer to verify the actual temperature. Consult the oven's manual for instructions on how to recalibrate the temperature settings if necessary.
Test the oven sensor: The oven sensor detects the temperature inside the oven and communicates it to the control board. Use a multimeter to check the sensor's resistance and replace it if it's defective.
