Sometimes, ovens don’t get hot. There can be a few reasons why. First, maybe the power isn’t going to the oven. Check if it’s plugged in and the circuit breaker isn’t off. Second, the heating element might be broken. That’s the part that makes the oven hot.

If it’s damaged, the oven won’t heat up. Third, the temperature sensor might be wrong. This part tells the oven how hot it is. If it’s not working, the oven won’t know when to stop heating. Finally, there could be problems with the oven’s controls. If the buttons or dials don’t work right, it can mess up the oven’s heating.

There are simple fixes for these issues, like replacing the heating element or recalibrating the thermostat. In this article, we’ll explore the common causes of oven heating problems and provide easy solutions to get your oven back up and running in no time!

Trouble with Your Oven Heating Up? Figure Out Why and How to Solve It!

Why Won't Your Oven Heat Up

1. Power Problems

If your oven won’t heat up, the first thing to check is if it’s plugged in. Look behind or underneath your oven to see if the power cord is properly connected to the outlet. Sometimes, it can come loose without you realizing it.

If it’s connected, try plugging another appliance into the same outlet to see if it works. If not, there might be a problem with the outlet itself, like a tripped circuit breaker or a blown fuse.

2. Faulty Heating Element

Your oven’s heating element is like the engine that powers its heat. Over time, these elements can wear out and stop working properly. You can usually tell if the heating element is faulty if it’s visibly damaged, like if there are cracks or breaks in the coils.

If you have an electric oven, you’ll typically have one heating element on the bottom for baking and another on the top for broiling. If either of these elements is faulty, your oven won’t heat up evenly or might not heat up at all.

3. Thermostat Troubles

The thermostat in your oven is what regulates the temperature inside. If it’s not working properly, your oven won’t be able to heat up to the right temperature. One way to tell if the thermostat is the problem is if your oven heats up but doesn’t stay at the set temperature.

For example, if you set it to 350°F but it only reaches 250°F and stays there, the thermostat might be faulty. In some cases, the thermostat can be recalibrated to fix the issue, but if it’s severely damaged, it might need to be replaced.

4. Igniter Issues

If you have a gas oven, the igniter is what lights the gas to create heat. If it’s not working properly, your oven won’t be able to heat up. One common sign of a faulty igniter is if you can’t see any sparks or flames when you turn on the oven.

Another sign is if you hear clicking sounds but the oven doesn’t ignite. In either case, the igniter might need to be cleaned or replaced. It’s important to handle gas appliances with caution, so if you’re unsure how to check or replace the igniter yourself, it’s best to call a professional.

5. Broken Bake or Broil Element

In electric ovens, there are separate heating elements for baking and broiling. If either of these elements is broken, your oven won’t heat up properly. You can visually inspect the elements for any signs of damage, such as visible breaks or cracks.

Sometimes the damage may not be visible, so you can also use a multimeter to test for continuity. If the element doesn’t have continuity, it’s likely broken and needs to be replaced. Fortunately, replacing a heating element is usually a straightforward task that you can do yourself with some basic tools.

6. Control Board Glitches

The control board, also known as the clock or timer, is the brain of your oven. It regulates the oven’s functions, including temperature control and timing. If the control board malfunctions, it can disrupt the oven’s heating ability.

Signs of a faulty control board include the display not lighting up, buttons not responding, or erratic behavior such as the oven turning off randomly.

Sometimes, resetting the control board by turning off the power to the oven for a few minutes can fix minor glitches. However, if the problem persists, you may need to replace the control board.

7. Temperature Sensor Problems

The temperature sensor, also called the oven thermostat, monitors the oven’s temperature and signals the control board to regulate it. If the sensor is not functioning correctly, it can cause your oven to heat unevenly or not at all.

Signs of a faulty temperature sensor include the oven not reaching the set temperature, heating too much or too little, or displaying error codes related to temperature.

Replacing the temperature sensor usually requires disconnecting the power to the oven and accessing the sensor inside the oven cavity. If you’re not comfortable doing this yourself, consider hiring a professional technician.

8. Gas Supply Interruptions

For gas ovens, a steady supply of gas is essential for heating. If there’s a disruption in the gas supply, your oven won’t heat up. Common causes of gas supply interruptions include a closed gas valve, a kinked or damaged gas line, or problems with the gas regulator.

If you suspect a gas supply issue, check to make sure the gas valve is open and the gas line is not damaged. If everything appears to be in order but your oven still won’t heat, contact your gas provider or a qualified technician to inspect the gas supply system.

9. Door Switch Faults

Modern ovens are equipped with safety mechanisms, such as door switches, to prevent accidents and injuries. If the door switch is faulty or not engaged properly, it can prevent the oven from heating up as a safety measure.

Check to see if the oven door is fully closed and the door switch is functioning correctly. You can usually hear a clicking sound when you open and close the door, indicating that the switch is engaged. If the switch is damaged or not working, it may need to be replaced to restore proper oven operation.

10. Dirty or Clogged Components

Dirt, grease, and food debris can accumulate inside your oven over time, especially around heating elements and vents. If these components become dirty or clogged, they can interfere with proper heating and ventilation, causing your oven to heat unevenly or not at all.

Regular cleaning and maintenance can help prevent this problem. Remove any visible debris from inside the oven, including on the heating elements, racks, and walls. You can use a damp cloth or sponge with mild soap to wipe down the interior surfaces.

Additionally, clean the oven vents and fan blades to ensure proper airflow. If your oven still won’t heat up after cleaning, there may be other underlying issues that require professional attention.


I hope this helps you understand why your oven might not be heating up and what you can do to fix it! Remember, problems like this can often be fixed with simple solutions like checking the power supply, the heating element, or the thermostat. If those don’t work, it might be time to call a professional to take a closer look. Don’t worry, though, with a little troubleshooting, you’ll have your oven working again in no time!
