Oven bottom heat defective – all the facts

If the cake remains somehow mushy and the roast is only cooked through from the top, then the suspicion is obvious that the bottom heat in your oven is defective. How big the problem actually is, however, is often difficult to determine without an expert. We show you here what the reasons for the defect may be.

What do I do if the bottom heat in the oven is defective?

If the cake remains mushy or the roast is only cooked through on the top, the bottom heat may be defective. This can be checked with an oven thermometer. If you know your way around, you can try to repair the damage yourself; otherwise, call an electrician.

Check suspicion

It all helps nothing, you have to check your suspicion that the bottom heat in the oven is defective by yourself first. Of course, the easiest method is to feel it with your hand while the oven is heating up. But there is also a less dangerous way, because you can hold a digital oven thermometer on the floor to see if there is any heat coming from the bottom at all.

Possible defects in the bottom heat

It doesn’t necessarily have to be the entire heating element that is defective if the bottom heat in the oven is no longer producing heat. Today, the heating elements of modern ovens are usually plugged into the power contacts with simple cable lugs. These age over time due to the heat and lose their spring force. Then the cable lugs slip out of contact somewhat and the current can no longer flow to the heating element.

Check and repair

If you have a lot of manual dexterity, you can check yourself if the cable lugs are firmly seated on the contacts with the fuse turned off. On some models, you also have the option of tightening this connection yourself with a fine pair of pliers. But as I said, you should have experience for this. Do not tinker with the electrical system if you are not familiar with it.


If you already know approximately which damage is present, the electrician does not need to search long and can possibly tell you in advance whether the heating coil in question is still available as a spare part. This saves you expensive hourly wages for an electrician who may not be able to do anything anyway.

You don’t have to immediately dispose of the whole oven if a part like the bottom heat is defective. First, check if it could be one of the very simple defects. Then you can always consider replacing the oven with a new one.
