Replacing the oven thermostat – Six simple steps!
1. Remove the upper oven cover and control knobs
First of all, make sure you have disconnected your oven. If your furnace is with gas burners, it’s essential for safety to close the gas supply.
Now, depending on the model, use a screwdriver or a wrench to remove the top cover of your oven. This gives you access to the area behind the control buttons. If you have electric hobs, the screws you need to loosen are usually on the sides or back of the plate.
If you have an oven with gas burners, first remove all removable elements to gain access to the screws; usually, there are two at each burner. The control knob for adjusting the temperature of your oven can generally be removed simply by pulling in your direction.
2. Remove the thermostat
Behind the control knob you just removed, you will see the small box, which is the thermostat. It is connected to power cables and a silver cable which connects it to the temperature sensor. First, take a picture of these connections so that you can reconnect them later. Then disconnect these connections.
With a mechanical thermostat, the temperature sensor is connected to it. Your new thermostat should come with its temperature sensor. Now unscrew the thermostat with a wrench or screwdriver.
If your oven is equipped with an electronic thermostat, locate and disconnect the connections, then unplug the temperature sensor connector.
3. Remove the temperature sensor
Open the panel of your oven and find the temperature sensor on the back wall of the oven. It is fastened with one or more screws to a holder, which is sometimes inside the oven or on the outer rear wall of the oven.

Now you can install the new thermostat. Carefully screw it onto the holder of the old thermostat and reconnect it to your original.
In some cases, after pyrolysis cleaning the oven might stop heating. The other thermostat causes this in the furnace known as safety thermostat. Safety thermostat is usually on the back of the oven. It is small, round and equipped with two cable lugs and a red button in the middle. Just press this button to re-enable it to solve the problem.
5. Replace the temperature sensor
Insert the temperature sensor through the small hole in the inside of the oven. Then attach it to its holder with the screwdriver just as the old temperature sensor was attached.
Did you know?
Some thermostat knobs are easy to set as they indicate the temperature directly. Others are numbered, usually from 1 to 8. How do you know what temperature the numbers correspond?
Multiply the number by 30.
For example, thermostat setting 6: 6 x 30 = 180 ° C
