Instant Reduced Heating Efficiency

Unit takes much longer than before to preheat or reach cooking temperature.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Partially failing heating element, Heavy grease insulating heater, Weak mains voltage, Failing temperature sensor

Safety first: Unplug and cool before cleaning or testing.

Clean heater and cavity: Remove grease buildup from the heating element and interior surfaces to improve heat transfer.
Check voltage: Avoid long extension cords; plug directly into a wall outlet to ensure full voltage.
Compare with thermometer: Use an oven thermometer to see if the unit eventually reaches the set temperature.
Replace heater or sensor: If preheat times remain abnormally long, test and replace the heating element or NTC sensor as needed.
