Whether it’s too hot or not hot enough, an oven that doesn’t heat up like it should ruin any meal. Why won’t my oven heat up correctly? It may need to be recalibrated to reflect the set temperature more accurately. Use these troubleshooting tips to solve the problem of a GE oven not heating properly.
How to Troubleshoot a GE Oven Not Heating Like It Should
A GE oven not heating properly typically has a straightforward cause and solution. These issues can be caused by various factors, such as wear and tear, power surges, or user error, and can prevent your oven from operating correctly. It may be helpful to conduct a thorough troubleshooting process to determine the specific cause of the oven not heating correctly.
Why Is My GE Oven Not Heating Up?
There are several reasons why your GE oven may not be heating up. Some of the most common include a need for calibration, a failure in the heating element, an issue with the oven ignitor, a blown thermal fuse, and a malfunctioning convection fan motor. After reviewing this troubleshooting guide, we recommend you call a professional for oven diagnosis and repair if your oven continues to have heating problems.
Oven Needs to Be Calibrated
If your GE oven isn’t heating to the set temperature, it may need to be recalibrated. While your oven is calibrated by the manufacturer, it can be adjusted if you feel it’s inaccurate. Some models have an adjustment screw underneath the control knobs, while specific buttons must be pushed on electronic controls. Most ovens allow you to raise or lower the temperature up to 35℉ for improved accuracy.
However, before recalibrating, make sure you always preheat your oven properly. Allowing the oven a full 20 minutes to heat up before cooking can ensure that it gets hot enough and maintains its temperature.
*Note: Calibrating your oven’s thermostat can be a delicate operation. If you aren’t experienced with this process, we recommend hiring an oven service professional to recalibrate the thermostat properly.
GE Oven Element Failure
Is your electric oven not heating properly? It may have a defective heating element. These metal coils at the top and bottom of the oven provide heat when they receive electrical current. The coils will glow bright red when operating properly and produce steady, even heat.
Signs of a defective GE oven element include:
- Uneven heating
- Blistering or breakage
- An uneven red glow
A defective heating element can’t be repaired and must be replaced. In some cases, the heating element can suffer damage after exposure to the high temperatures of the oven’s self-cleaning cycle. Our oven cleaning tips recommend cleaning with a vinegar solution to prevent damage to multiple components.

GE Oven Igniter Failure
For gas ovens, a GE oven not heating up properly is often due to a failed igniter. This component must generate enough electrical current to open the valve, allowing gas to flow and producing a spark to light the gas. If it can’t perform one or both of these tasks, the oven won’t heat up at all.
How can you tell if your GE oven igniter has failed? Observe it after turning on the oven. When it takes longer than 90 seconds for the gas to ignite, the igniter may be too weak to open the gas valve or ignite the gas. If multimeter testing confirms this with a lack of continuity, it requires replacement.
Blown Oven Thermal Fuse
A thermal fuse is a safety device that blows if the oven is in danger of overheating, preventing damage to other oven components. A GE oven not heating up properly or a lengthy self-cleaning cycle can result in high temperatures that cause the fuse to blow. It may also blow if it’s defective.
Multimeter testing of the fuse can confirm that it’s blown with a lack of continuity. A blown fuse can’t be repaired and must be replaced for the oven to function.
*Note: An oven thermal fuse will rarely blow for no good reason. Chances are that a blown a fuse is due to another problem with the oven. We recommend service from an oven repair specialist who can identify the root cause and help you avoid yet another blown fuse.
Convection Fan Motor Failure
Convection ovens utilize a fan to circulate the hot air inside, resulting in faster cook times and more even heating. If the fan’s motor fails, it won’t be able to circulate the air, leading to longer preheating and cooking times and uneven heating.
The convection fan is found inside your oven’s back panel and can be difficult to remove and test. If you notice noise coming from the fan or if your oven is experiencing uneven cooking results, we recommend having it checked by an appliance service professional.
How Do I Fix My Oven That Won’t Heat?
In addition to the above most common reasons, a few other components may be attributed to the oven failing to heat.
- A malfunctioning bake or broil spark electrode – Visually inspect the electrodes for any physical damage or debris and ensure they are securely connected to the oven’s electrical circuit.
- A problem with the safety valve – Locate the safety valve, which is usually near the gas supply line, and listen for a hissing sound when the oven is turned on. Some models also have a valve testing bottom that, when pressed, will check if the valve is operating correctly.
- Damaged wires – Using proper safety measures, visually inspect the wires for any physical damage or loose connections, and ensure they are securely connected.
- Faulty oven control board – A malfunctioning control board can prevent an oven from heating. If you suspect the control board is to blame, a professional oven repair technician will provide you with a proper diagnosis and repair or replacement of the control board.
Why Is My Oven Not Getting Up to Temperature?
One of the more annoying common oven failures is when your oven still heats but not to the correct temperature you selected. An oven that doesn’t heat enough is usually experiencing one or more part failures. For gas units, a broken igniter or gas valve can cause there to be a deficiency in the amount of gas being ignited inside the oven, while electric ranges tend to be dealing with a faulty heating element.
Both gas and electric ovens can stop heating enough due to a defective temperature sensor, thermostat, or even the main control board. Avoiding these issues is simple, though. Just make sure to follow frequent, safe cleaning practices, and avoid using your self-clean function.
Why Does My Oven Not Heat Evenly?
Another repair issue we see frequently is an oven not heating evenly. No one wants to eat a cake that’s half cooked and half mush! Similarly to when an oven doesn’t heat enough, uneven cooking is usually caused by a failed bake element, broil element, or igniter. A less common reason would be a broken temperature sensor, but even something as simple as the placement of your oven racks, opening the oven door too often while baking, or the cookware you’re using can lead to uneven cooking.
