How do I fix my oven that won’t get hot?

Like with a heating element or gas igniter, replacing the temperature sensor is a quick and easy fix you can do yourself. Cause: If it’s still not heating to the correct temperature and you’ve checked or replaced the heating elements, gas igniter and temperature sensor, it may simply need to be calibrated.

An oven that won’t heat is usually the result of a faulty igniter (for a gas oven) or heating element (for an electric oven). You may be able to replace the heating element or igniter yourself: Make sure to turn off the power to your oven before servicing it.

Unplug the microwave and then access the fuse from inside the cabinet which is near the power cord. To check the continuity of the ceramic fuse, make use of a multimeter. If no continuity is observed, you may have to replace the fuse.

A soft reset is simply turning off the microwave oven to cancel or erase the program you’ve input in the microwave. To do this, you will just simply press on the Off/Clear button. Pressing Off/Clear button and holding it for about 3 seconds will also resolve the Control Locked feature of the microwave.

Reset the electronic control. Turn the circuit breaker to the OFF position or remove the fuse. Wait one minute, then turn the circuit breaker back to the ON position or install the fuse to reset power to the unit. This should reset the electronic controls on the range or wall oven.

Most microwaves contain at least a main fuse or line fuse and a thermal fuse or thermoprotector. The main fuse is usually a narrow, rectangle shape, two inches in length, and either a ceramic fuse or a glass fuse with a filament.

Microwave ovens use one or more thermal cut-outs, sometimes called thermal fuses, to protect the oven from overheating. They are located inside of the cabinet, often near the oven cavity or the magnetron. If the thermal cut- out fails, power is interrupted to the controls or to the control outputs.
