In order to produce the heat that cooks your food, your electric oven uses heating elements. It uses a broil element that you can typically see at the top of your oven tub and a bake element at the bottom that may be hidden under a protective metal covering. Most oven owners only believe that they have one heating element, the broil element that they can see. However, the majority of the oven’s heat comes from the unseen bake element. Knowing this can often help you diagnose which element is faulty more quickly. However, there are some other signs to look for.
Diagnosing a Faulty Broil Element
If you believe you have a faulty broil element, then your oven will only be slightly cooler if it is not working. In fact, you may not even notice a difference despite some longer cook times on food. To concretely test if the broil element is faulty, all you need to do is turn the oven to its broil function. This function uses solely the broil element in order to produce heat and radiate it down to items on the top rack.
After a preheating period on the broil setting, the coil should glow bright orange or red. If you notice patches that are not glowing or are glowing a different color, this is a good sign that you will need to replace your broil element. This means that the element is not working as it should be due to damage or overall wear.
Diagnosing a Faulty Bake Element
If it is the often hidden bake element of an oven that has gone faulty, you will likely notice it pretty fast. This is the workhorse of your oven when it comes to heat. When it is not working, it will feel significantly cooler inside the oven tub and may take ages for food to cook.
As you cannot see a bake element in most newer designs, a visual inspection won’t be easily done. However, after a preheat cycle is done, you will be able to feel if it is working. If you do want to do a visual inspection, the metal plate covering the bake element can be removed and the preheat can be run. Similar to a faulty broil element, a working bake element will have even coloring and no patches of discoloration.
There is a chance it could be electrically open and a simple continuity test is required when either element has been removed from the oven completely.
How to Replace a Heating Element
When an oven’s heating element goes out, as it is central to its function, you may imagine it is difficult to replace, but that is not the case at all. You will need to diagnose which element has gone out as well as find the make and model of your oven to purchase a replacement element.
Once the replacement is in hand, you will need to shut the electricity to the oven off at the circuit breaker for your safety. Once done, you will need to be able to clearly access the heating elements. This will mean removing any oven racks and removing the plate above the bake element if necessary Once you have access, you will need to remove the mounting screws that secure the element to the oven. Afterward, you will need to remove the screws securing it to the back oven wall. If you are replacing a broil element, you will need to brace it so it doesn’t fall down. Once the last screw is removed, gently pull the element forward and disconnect the two wires located behind the backplate.
Once the old element is removed, the new heating element can be connected to those same wires and the screws can be put back in place. If doing a broil element, you may want to recruit some help so you can get it properly aligned.
