Why Is My Oven Not Heating Up Properly?

It can be really disappointing when you really want to cook a great meal, but your oven just doesn’t heat up. You really try your best to make it heat, but it doesn’t work. It may even be worse if you wanted to cook a special meal for someone, but the oven issues create an unnecessary delay. Worry no more; there are specific reasons that may bring about this issue. Knowing where the problem is will help you to get a quick solution.

Convention Oven Appliance

Your gas or electric oven may not be heating up properly because of problems with the parts below:

The heating elements

This is the most probable cause of ovens not heating properly. There are two heating elements – one at the top (broil element) and another one at the bottom of the oven (bake element).

When both elements are working fine, you will see a bright yellow or orange glow emitted by the burner. If there is warmth in the oven, but not the correct temperature, take a look at the heating elements. If either element appears separated or blistered, you will need to replace it. However, if they look normal, turn the oven on for 60 seconds then turn it off. If either element is still cold, it is definitely defective.


This is another common part that can be defective if your gas oven is not heating the way it should. This part has two functions – drawing electrical current through the safety valve to open the oven and igniting the gas in the burner. To check whether the igniter has issues, first observe it while the oven is on. If it glows for 1.5 minutes and doesn’t ignite a flame, then it is so weak that it cannot open the valve. This needs replacement. If it doesn’t glow at all, you can test it using a multi-meter. If there is no continuity, then arrange for a replacement.

Temperature sensor

The temperature sensor measures the temperature of the oven. It signals the heat elements to either turn on or off. It is located near the broil element. Your oven may display an error code if there is a problem with the sensor. You can also use a multi-meter to check for errors.

Electronic control board

Modern ovens use this to control the functions of the oven. This controls the broil and bake elements. If there are no error codes displayed, check to see if there is a power supply to the elements. You can ask a qualified person to do live voltage checks. Without an output voltage, you should replace the control.

If your oven is not heating up properly, there are high chances that the parts mentioned above have faults. Other parts that may cause the problem include the control thermostat, fuses or spark electrodes. In some instances, the entire oven may not work if there is a problem with the electrical system that connects to the oven (this can be fixed by simply plugging it into another socket).

Replacing the above parts will help you fix the issue of the oven not heating up and you can gladly get back to cooking and enjoying great meals with your loved ones.
