Why Is My Electric Oven Not Heating Up? 5 Causes and Solutions

1. A Tripped Circuit Breaker

Electric ovens generally require 240 volts to operate, which is why they often have a dedicated circuit and outlet. In some cases, switching the oven on might cause the breaker to trip, cutting off its power. This could happen due to something minor or because of a more serious issue like a wiring fault.

The Solution

Go to your breaker panel and locate the switch linked to your oven. Flip it back to the “on” setting to reset it.
If the oven keeps cutting out or won’t heat up when you try to use it, it’s best to contact a nearby appliance technician. There could be a deeper problem with the wiring or an internal part that needs professional attention.

2. A Broken Thermostat

Ovens rely on a thermostat or sensor to monitor the internal temperature and determine when it hits the set level. If that component malfunctions, the oven can’t accurately detect how hot it really is. When it mistakenly senses that the temperature is higher than it actually is, the oven may stop heating altogether.

The Solution

The temperature sensor is often visible inside the oven, typically as a slim rod located near the back wall. For accurate readings, it should be positioned at a right angle, but it might get knocked out of place over time.
If that happens, carefully adjust it back to its proper position. If you’re unsure whether it’s misaligned or you’re having trouble locating it, it’s a good idea to get help from a professional SD Appliance Repair technician.

3. A Broken Heating Element

Electric ovens typically feature heating coils at both the top and bottom, which glow red as they heat up. If there’s an issue with one of these elements, the oven might not reach the proper temperature—or heat at all.
You might notice visible damage, such as cracks or blisters, indicating the element is worn out. In some instances, a build-up of dirt or grime could also interfere with its performance.

The Solution

Regularly cleaning your electric oven, whether through its self-cleaning feature or manually scrubbing, can improve the longevity and effectiveness of the heating elements.
If the element is beyond repair, replacing it might be necessary. While you could attempt the replacement on your own, it’s generally safer to have a professional SD Appliance Repair technician handle it.

4. The Oven’s Knobs Are Misaligned

Although many newer electric ovens have swapped out traditional knobs for push buttons and digital controls, temperature knobs are still commonly found in many models.
Just like the internal temperature sensor, the external knobs can sometimes become misaligned, which might stop the oven from heating to the right temperature.

The Solution

If the temperature knob is faulty, replacing it could be the solution. Check the knobs for any visible damage like cracks, or see if they’re clogged with dirt, as this can cause them to stick or not turn smoothly.
Replacement knobs are typically easy to find, whether you search online or visit a local store, depending on your oven’s brand and model.

5. The Door Doesn’t Seal

Just like you’d keep your home door shut during winter to keep warmth in, it’s important not to leave the oven door open while cooking. Otherwise, the heat will escape, giving the impression that the oven isn’t heating properly.
If the pan you’re using is a bit too large, it might prevent the door from closing fully. Another possibility is that the door’s seal could be damaged or simply needs a good cleaning.

The Solution

Each time you use your oven, double-check that the door is securely shut. Also, ensure your pans and baking trays are the correct size for your oven.
If you suspect the issue is with the door’s seal, inspect it closely. A buildup of grease or dirt could be interfering with the seal, or it may have deteriorated over time. In these cases, replacing the seal should help the door close properly.

Signs of Oven Temperature Trouble

One clear indication of a temperature problem is when your oven doesn’t heat up at all. However, it could also be that the oven isn’t reaching the right temperature or is heating inconsistently. Common signs of temperature-related issues include:

• Longer cooking or baking times than usual
• Foods that cook unevenly (like being burnt in some areas but cold in others)
• Heating elements that fail to glow orange-red

When to Call a Pro

If you’re not sure about fixing a tripped circuit or adjusting the thermostat yourself, it’s a smart idea to call a professional. An expert can assess the situation and suggest the best solution, whether it involves repairs or replacing the oven entirely.
