We’ve all been there: you’ve carefully prepped your ingredients, mixed everything together just right, popped your culinary masterpiece into the oven, set the timer, and…nothing. Frustration sets in, the meal is ruined, and the worst part is, you don’t know why it happened or how to fix it. That’s where we come in! Just follow these steps to figure out why you have an oven not heating up properly.

How To Fix Your Oven Not Heating Up

If you find your oven not heating up, don’t worry, you’re not alone! Below we delve into the top five causes of an oven not heating up and how to solve them.

1. Is Your Oven in Demo or Child Lock Mode?

Are you wondering why your oven seems to have everything except heat? It might be in Demo Mode or Child Lock mode. Demo mode

Does your oven appear to function except for heating up? It’s possible that your oven is in Demo Mode or Child Lock Mode. Both these modes are safety features—Demo Mode for showrooms and Child Lock Mode for households with young children.

Disabling Demo Mode

Your oven’s control panel should provide an option to turn off Demo Mode. Usually, you’ll press the Options or Settings button, navigate to Demo Mode settings, select the disable option, and confirm your selection.

If this doesn’t work, try pressing and holding two marked buttons (like “Demo,” “Mode,” or “Settings”) simultaneously for about 3-5 seconds until you receive a confirmation.

Disabling Child Lock Mode

The process is similar to disabling Child Lock Mode. Check your oven’s control panel or user manual for specific instructions. Usually, it involves pressing and holding a specific button or combination of buttons until the lock symbol disappears from the display. You may see a button labeled child lock on some models as well.

2. Oven Door Issues

What causes an oven to lose heat? Sometimes, it’s the simplest things that can cause this issue, and an improperly closed oven door is one of them. A fully closed oven door is essential for retaining heat and cooking your meals correctly. If you’ve left the door ajar or if it’s not closing all the way, your oven might not heat up as expected.

Electric oven not heating up properly

There are a couple of common issues that might prevent your oven door from closing completely:

Door Latch Problems

The oven door latch is a critical component that keeps the door securely shut. If it’s broken or misaligned, the door might not close correctly. Inspect the latch for any visible signs of damage. If it’s loose or misaligned, a screwdriver can typically be used to tighten or realign it. However, if it’s broken, you might need to replace it.

Obstructions in the Door Path

Sometimes, food particles or debris can accumulate in the oven door path and hinder its closing. Check the path for any obstructions and clean them out if necessary. Be sure to check the door seal as well — a damaged seal can prevent the door from closing fully and may also allow heat to escape, reducing the efficiency of your oven. Clean your oven often to avoid issues like this.

3. Power Issues With Your Oven

Just like any other appliance, your oven needs power to function. If your oven’s not heating up, it could be because of an issue with the power source. Here’s how you can check:

  • Ensure that your oven is correctly plugged in.
  • Confirm that the outlet is providing enough power. Electric ovens require a 240-volt connection for heating.
  • Check the circuit breaker for a blown fuse. If your oven stopped working while cooking, this may be the issue.

Remember, even gas ovens need an electrical connection to power certain functions.

4. Your Oven Thermostat May Need Calibration

Sometimes the issue isn’t that the oven’s not heating, but that it’s not heating enough. The oven’s thermostat works to maintain the set temperature, but it may need recalibration to improve its accuracy.

You can test your oven’s temperature by baking something simple, like biscuits. Follow the cooking instructions carefully. If the biscuits come out undercooked or unevenly cooked, your oven might need recalibration. If you have an oven thermostat, you can use this to see if your oven is getting to the correct temperature. You’ll find the exact instructions on how to recalibrate your model in the oven’s user manual, but this may be a job you would rather let a professional take care of.

Gas oven not heating up enough

5. A Defective Oven Heating Element or Igniter

For electric ovens, a defective bake element (the metal coil at the bottom of the oven) can be the reason for your electric oven not heating up or your oven cooking unevenly. If this element is damaged or malfunctioning, it won’t produce heat. Look for visible damage like blistering or breakage, a spotty red glow, or a lack of continuity when tested with a multimeter. If it’s defective, it will need to be replaced.

In the case of a gas oven not heating up enough, a faulty igniter can prevent your oven from heating. The igniter both opens the valve that allows gas to flow and ignites the gas with a spark to heat the oven. If it’s too weak to light the gas or takes more than 90 seconds to do so, it requires replacement.
