Electric oven takes a long time to preheat

Electric oven takes a long time to preheat. Heating our foods used to take the taste of our food away completely in the past. But with time, the ovens came into existence.

They preserve the natural flavor of food using microwaves. They were mainly built to save time.

But what if our oven starts taking a lot of time in the process of preheating? They were supposed to save time, but that doesn’t seem to be the case now.

Sometimes the thermostat of the oven becomes faulty, so it takes more time to preheat. It also takes time to heat because, at times, the boards and circuits are damaged.

The hidden elements, being the root of this issue, are pretty common. The reason might be a bit different. It can be that the hot air is escaping from it by leaking. The issue can also relate to power.

At times, the heating elements of the electric oven, because of excessive use, wear out. They might not be able to perform their functioning as they used to before.

Some fault in the primary control has appeared. That fault prevents the proper use of the device.

The heating element performs the principal task in the oven. But if the elements of the microwave are damaged, you will not be able to heat your food. Other reasons are listed below.


Calibration of the thermostat may be needed, as a thermostat is an important component in the device. It is responsible for keeping the temperature in check.

The device is set such that it will not work if the thermostat is missing or facing some problem within.

They are easily replaceable, and you can replace them at home, but if you want a professional, then that is your choice.

Boards and circuits

Boards and circuits are the main parts f the device. Their functioning is necessary for the proper working of the device. With the presence of any fault, they will not allow the device to perform its task.

You need to check if there are missing parts or not. The boards and circuits as internal faults need to be checked by a professional only he can determine if they are repairable.


Fuses are an important part of any electrical circuit as they are responsible for safety as well as the flow of current.

A melted or missing fuse will not allow the current to pass through, and thus the current will not reach the device and resulting in not just delay but no heating as well.

You should always check the fuses before use. Make sure they are not missing.

And if they are missing, make sure that is not melted. If they are melted, you need to replace them same goes in the case of them being missing.

Hidden element

As is explained above, the heating element of some microwaves is hidden, so they take a long to preheat than others. This is not actually caused by any kind of fault. Rather, it is that they are manufactured that way.

There is no way to fix it as the devices are manufactured that way, but there is a way to prevent it.

That is that you need to check if the element is hidden or not when you buy a new one. Good brands do not manufacture them like that, so you do not need to be worried.

Damaged seal

The outer seal is installed and has such a design that it doesn’t allow the heat to escape from it. It keeps the heat in circulation.

But if the seal is damaged, which happens with time, then the eat will not be able to circulate properly, and the heat will be lost. Making the process slow.

The seal can be replaced if you take it to a professional or send out back to the manufacturer, but it is better to purchase a new one.


The slow heating of your appliance can cause a delay in the actual heating process. It is better to get the issue fixed before it might result in something big.

Sometimes the oven does not heat up the food at its original timer due to a fault in the thermostat, some damage in the seal, or a fuse in an electrical circuit.

You should hire a verified professional to fix this issue.
