What to Do When Your Oven Won’t Turn Off
If your oven won’t turn off, you are in a potentially dangerous situation. There are many reasons why your oven isn’t shutting off like it’s supposed to. In this guide, we will look at those reasons and explain what you should do if you find yourself with an oven not turning off.
Common Reasons Why Your Oven Won’t Turn Off
As you will see below, there are actually quite a few reasons why your oven won’t turn off. If you’re asking yourself, “Why does my oven stay on when I turn it off?” you may find your answer in the following examples.
Oven Control Board
The oven control board consists of relays that provide voltage to the bake and broil circuits depending on your user settings, as well as the sensor input. The control board can end up sending continuous voltage to your oven’s heating circuit if one of the control board’s relays shorts and closes.
Furthermore, if the oven continues to stay on even after you have turned it off, it’s a good sign that the control board is defective. When this happens, the best thing to do is replace the control board altogether.
Temperature Control Thermostat
This component is responsible for monitoring the temperature inside your oven. If your oven’s temperature happens to get too low, it will cycle on the heat. And if the thermostat that controls the temperature fails, your oven won’t heat up at all.
It’s important to note that this doesn’t happen a lot. So before you replace your oven’s thermostat, you should first check for components that are commonly defective, such as the igniter or the bake and broil elements.
If any of these components are functioning as designed, you might need a new temperature control thermostat. This can be tested, but it’s usually better to replace the thermostat.
You might have a short in the oven if your heating element burns out. If it becomes shorted out, your oven won’t shut off. What’s more, you’ll be able to clearly see if this component is defective, as it will display blisters or holes. Use a multimeter to be sure, but it will likely need to be replaced to get you back up and running.
