Why Gas Oven Turns On By Itself

Few things are more spooky than a home appliance that turns on by itself. While that might be the stuff of horror movies, it can be a reality when it comes to gas ovens. Even though it’s unlikely, gas ovens are known to turn on themselves.

A gas oven can turn on by itself if there’s a fault with the temperature sensor, control panel, main control board, or electrical wiring.

Keep reading as we help you uncover what causes this problem and how it can be fixed.

The most likely reasons your gas oven turns on by itself are a problematic temperature sensor, faulty control panel or program selector, stuck relay on the main control board, or wiring and electrical problems.

Tip: Before Troubleshooting Or Repairing Your Gas Oven

Like most people, you’re probably keen on getting started right away. However, there are a few safety precautions you should take first.

For starters, always disconnect the oven from its electrical power supply. Then, shut off its gas supply as well. Doing both of these things will reduce your risk of injury and electrocution.

Also, be sure to keep your user manual or tech sheet nearby for easy reference.

Now that you’re prepared let’s look at the most likely reasons your gas oven turns on by itself.

Problematic Temperature Sensor

What it is: Gas ovens come equipped with a temperature sensor. You’ll find it attached to the back wall, typically at the upper-left or upper-right corners. The sensor looks like a short metal rod that sticks out into the oven compartment.

The temperature sensor continuously measures how hot the oven is at any given time. That data triggers the oven to heat up or cool down as needed.

How it fails: Normally, the temperature sensor will not work while the oven is turned off. However, a faulty sensor will continue measuring the temperature and mistakenly think it should trigger the oven to turn on.

As a result, your oven will turn on by itself even when you don’t want it to.

How to fix it: Faulty temperature sensors must be replaced, as they’re not the kind of components that can be repaired. So, once the oven is cooled down and safety precautions have been taken, open the oven and locate the temperature sensor.

Next, unthread any screws holding it in place and disconnect the wire connector when you pull the sensor out.

Then, simply attach the wire connector to a new sensor and mount it onto the same part of your oven’s compartment.
