Oven Not Heating Up? Here's What Might Be Wrong

It’s frustrating when your oven won’t heat up, especially when you’re in the middle of making a meal. You count on it to work every time you turn it on. So when it doesn’t, it can throw off your whole day. But you're not alone — this can be a pretty common issue, and many causes are easy to spot once you know what to look for.

Let’s go over some of the most common reasons for an oven not heating up — and how to resolve them.

5 Reasons Your Oven Isn’t Heating Up

Ovens stop heating for a few key reasons. Some issues are easy to identify and fix yourself, while others may require help from a professional. Read on to learn what could be causing your oven to stop heating.

1. Heating Element Is Broken

In electric ovens, the heating element is the metal coil that creates heat. If it’s damaged or burned out, your oven won’t produce heat. You can easily spot a broken heating element by turning the oven on and looking for a red glow.

If the coil stays dark, looks cracked, or has blisters, it has probably failed. To fix this, you’ll need to unplug the oven and replace the heating element with a new one that matches your model.

2. Gas Igniter Is Faulty

Gas ovens need an igniter to light the burner. If the igniter is weak or worn out, it won’t light the gas, and your oven will stay cold. A good indicator of a damaged igniter is a clicking noise when turning on the oven, or a burner taking a long time to light or not lighting at all.

If that’s happening, the igniter likely needs to be replaced. Since it involves working with gas, it’s safest to let a licensed technician handle the repair.

3. Temperature Sensor Isn’t Working

Your oven’s temperature sensor monitors the heat inside and tells it when to turn the heat on or off. If it’s broken or knocked out of place, your oven might not heat properly, or at all.

The sensor looks like a slim metal rod inside the oven. If it’s bent or touching the oven wall, it can cause heating problems. Try gently adjusting its position or replacing it if you can see that it's damaged.

4. Control Board Is Malfunctioning

The control panel acts like the brain of your oven. It sends signals to the heating elements or igniter to turn on. If the board is faulty, the oven may not heat up at all. This problem usually needs a professional diagnosis. If you’ve ruled out the heating element, igniter, and sensor, the control board may be preventing your oven from heating.

5. Power Supply Is Disrupted

If your oven isn’t turning on or only the lights are working, the power supply might be the problem. Electric ovens usually require a 240-volt connection, while gas ovens still require electricity for things like the igniter.

Check your circuit breaker and make sure the plug is fully inserted. If the breaker keeps tripping, you’ll need an electrician to look more closely.

Can You Replace the Oven Heating Element Yourself?

Yes, in many cases you can. Replacing a heating element in an electric oven is often a straightforward job. You’ll need to unplug the oven, remove a few screws, and swap the old element with a new one that matches your model.

Make sure the oven isn’t connected to a power source and always double-check the part number. Refer to your owner’s manual as needed.

Should You Repair or Replace a Broken Oven?

Whether you should replace or repair your oven depends on the problem, its age, and how much oven repairs will cost. If your oven is newer and the fix is simple, a repair usually makes the most sense.

But if your unit is older or the parts are expensive, it may be better to replace it. A home warranty from First American can help repair or replace covered ovens.

FAQs About an Oven Not Heating

Why is my oven not heating up, but the stove works?

If your stovetop still works but the oven doesn’t, it’s often due to a faulty heating element or igniter. The stovetop and oven use different parts, so one can work even if the other doesn’t.

Why does my oven take so long to preheat?

A slow preheat time can mean the heating element is wearing down or the temperature sensor isn’t working correctly. It could also be due to poor insulation or frequent door opening while the oven is preheating.

How do I maintain my oven to prevent heating problems?

Some routine oven maintenance can help you avoid major issues, especially ones that prevent your oven from heating up. Clean your oven regularly, avoid blocking the vents, and check the heating elements and temperature sensor for any visible wear. Also, avoid using harsh cleaners on the sensor or heating elements.
