Here are 7 common De’Longhi oven problems, along with their solutions, to help you deal with any trouble.

De’Longhi oven is not turning on

At times, your De’Longhi oven won’t turn on or respond to any of the buttons or dials on the control panel.

If your food turns out to be undercooked or not cooked at all, your oven may have a heating issue.

De’Longhi oven, not heating is typically caused by faulty baked elements. 

But there’s nothing to worry about, as the solutions mentioned below can help you fix the issue in no time.

Possible solution(s):

  • Test the baked element of your oven by observing for cracks and inconsistencies in its red glow. If the bake element appears to be defective, replace it to fix your oven.
  • If the bake element appears to be working as expected, test the igniter. If the igniter glows for more than 90 seconds without ignition, replace the igniter, and your oven will start heating as expected.

The oven light can be of great help when it comes to cooking food, as it allows you to pull it out at the perfect time.

But at times, your oven’s light won’t turn on.

However, De’Longhi ovens can often run into issues when it comes to self-cleaning. But the below-mentioned solutions can help you fix your oven.

What do the reviews say?

I use this convection oven almost every day. For years I had used a DeLonghi oven, and when it finally stopped giving me service, I tried to find another.

In the meantime, I bought some others, but none of them lasted as long as my first DeLonghi.

Finally, I found this one at Best Buy, and it is just as good as my first-in many ways better.

I would recommend this oven to anyone looking for a fantastic cooking device.


This convection oven is quite compact and powerful. It replaced a larger and less effective model we had for several years.

The design allows for easy movement of racks for cooking different food and cleaning the entire oven.

I highly recommend this product to anyone wanting to get the biggest bang for the buck.


This oven does it all. Defrosts, toasts, bakes, broils, and rotisserie, all for a great price.

I bought it mainly for the rotisserie but got so much more for the money.

No need for my toaster and microwave anymore, which will give me more counter space! Very pleased with this oven!
