Issues with the thermostat, selector switch, or
Depending on your type of oven, a possible reason your oven is not heating may be due to a faulty igniter in gas ovens or a broken heating element in electric ovens. These parts are the source of your oven's ability to heat, and if they aren't working, your oven won't be able to perform its job.
The oven temperature sensor is broken or faulty
One of the most common issues that causes an electric oven to be unable to heat up at all is a broken or faulty oven temperature sensor.
The most likely explanation here is that not enough fuel is being burnt quickly enough to generate the heat output capabilities. When lighting the fire it is important to get the appliance very hot and to establish a glowing fuel bed before adding new fuel. This enables new fuel to start burning straight away.
The cost to replace a heating element in an oven is $150 to $450. A new heating element for an oven costs $15 to $100 for the part alone. Ovens have 2 heating elements, the baking coil, and the broil element.
The possible reasons your oven is not working may include a broken baking or broiling element, a malfunctioning spark element (spark electrode), a broken igniter, a blown fuse, an issue with the control board, or outlets not providing enough power to the oven.
First, check that the sensor is in its proper position and move it into place if necessary. Then check that the oven is measuring temperature in the proper metric. If the sensor or the temperature settings aren't the cause, you may need to recalibrate your oven.
If the stove works fine, but the oven is not heating up, it means the baking and broil elements are functional, but you may have a blown internal fuse case. Our specialists confirm that there may be numerous other factors at play, and there are several potential solutions worth exploring: Check power outlet.
The element is the most vital part of an electric oven. Without it, your food will remain uncooked and cold - so when your cooker element breaks, it's important to find the correct replacement quickly.
The heating element will stop working. The sparking ceases after a few seconds. There may also be a "burning plastic" odor at this time. We recommend that you not use the oven if the bake or broil element fails.
Turn the circuit breaker to the OFF position or remove the fuse. Wait one minute, then turn the circuit breaker back to the ON position or install the fuse to reset power to the appliance. This should reset the electronic controls on the Range or Wall Oven.
If your oven isn't heating up, it may be because the igniter or heating element is damaged or isn't working properly. Make sure to inspect the temperature sensor for any visible damage and the gas line for any leaks or defects, as an unobstructed gas supply is essential for your oven to heat up effectively.
Make sure the multimeter is calibrated and then turn the dial to the lowest ohm rating. Place the multimeter on the thermostat. If the thermostat has a reading of zero or as close to zero as possible, it is working fine. However, if it has no reading at all, your oven thermostat is faulty and will need replacing.
An oven that isn't heating properly may have a damaged heating element that needs to be repaired or replaced. If your oven has any exposed bake or broil elements, check for visible breaks or blisters. You can also visually check to make sure all oven elements are turning on.
Most oven heating elements last quite a few years, but just like any other appliance part, eventually they wear out or can break if something falls onto them. No need to panic. Thankfully, replacing your oven's element is a simple repair to make, as you only need a screwdriver.
The rule of thumb is that if repair costs exceed 50% of the price to install a new oven, you should buy a new oven instead of replacing it. For example, if your oven costs $2,000 but costs $1,500 to repair, you could use that $1,500 for a new and improved oven.
The most common problem with oven elements is when the oven light and fan come on but the oven element won't heat up at all. This is the classic sign that the element needs replacing.
