However, caution is advised; if you're not comfortable, it is better to hire a professional to avoid unintentional damage. Addressing electrical wiring concerns, when done correctly, can alleviate the issue of overconsumption or misdirection of electrical current.

Faulty Heating Elements

One of the most common culprits behind why an oven not heating properly is the malfunctioning of the heating elements. It’s crucial to understand the role they play in the functioning of your oven. These elements, usually found at the top and bottom of your oven, are responsible for generating the heat necessary to cook your meals evenly. When either or both of these elements fail, your oven may take significantly longer to heat up, or it may not heat at all.

You might first notice this problem if your food isn't cooking evenly, or if it's still undercooked even after the usual baking time. To investigate, you can visually inspect the elements once the oven has cooled. Signs that an element is burnt out include visible damage such as breaks or blisters, as well as an element not glowing bright red when the oven is on. It's akin to the filament in a light bulb burning out; when it doesn't light up, it doesn't work.
