AEG ovens are well known for their reliability, durability, and ease of use, but just like any other electrical appliance, they may encounter a few problems throughout their lifetime.

If your AEG oven is not heating up, you may have to check if it was installed correctly, or you might have to replace a damaged door seal, a defective fan element, or a broken oven thermostat.

In this article, we will discuss the possible reasons why your AEG oven isn’t heating up and how these issues can be remedied. Let’s dive in.

AEG Oven Not Heating Up: Here’s Why and How to Fix It

Check That Your Oven Was Correctly Installed

If your oven was recently installed and you’ve found that it isn’t heating up, it may be because the oven wires weren’t properly connected by whoever installed your oven. Don’t worry, though, because this is an easy thing to fix, and all you’ll need to do is a set of screwdrivers, like this CRAFTSMAN Screwdriver Set.

How to Fix It

  1. First, make sure you’ve disconnected your oven or switched it off at the switchboard.
  2. Unscrew the screws that are holding the oven in place. They should be located around the rim of the oven cavity once you open the door.
  3. Remove the oven from the frame and put it on a sturdy work surface nearby.
  4. Unscrew the back panel to reveal the wiring underneath.
  5. Check to make sure that all of the wires are connected properly. If they are not, clip the connectors back onto the oven and make sure they are secure.
  6. Now you can screw the back panel back into place, put the oven back into its frame, and secure it there with the screws on the front of the oven.

If this doesn’t seem to be causing the problem, don’t worry, there are still other things you can try.

Replace the Door Seal

A worn-out or damaged door seal can lead to a loss in hot air inside of your oven, which means that it won’t heat up or cook your food efficiently. Luckily, this is a relatively simple thing to fix. It doesn’t even require any tools. All you need is a new seal to replace the old one with.

How to Fix It

  1. Make sure you disconnect your oven from the power source. It’s always better to be safe rather than sorry.
  2. Open the oven door to expose the seal. It will be sitting around the rim of the oven cavity.
  3. Remove the old seal by pulling gently on one of the corners. Work your way around until you’ve removed the seal completely.
  4. Wipe down the groove with a wet cloth or a sponge to get rid of any dirt. Let the groove dry before installing the new seal.
  5. Install the new seal by lining up one of the corners to the groove on the oven rim and pressing down firmly to secure it in place. Do so around the rim until your new seal is secured completely in place.

Replace the Fan Element

If when you switch your oven on, the fan runs and the thermostat light comes on, but the oven doesn’t heat up, this means that the element has failed and will need to be replaced. However, you can replace the broken element yourself with just a set of screwdrivers, a replacement element, and some time.

How to Fix It

  1. Switch off the power supply to your oven before starting.
  2. Remove the oven door. To do this, open the door all the way to expose the hinges. There’s a clip on each hinge that you’ll need to pull back to unlock the door from the hinge. Close the door about halfway and slide it away from the oven.
  3. Remove the oven shelves and shelf racks to gain access to the backplate.
  4. Unscrew and remove the backplate to expose the fan element.
  5. Unscrew the screws that hold the element in place and carefully pull the element into the oven cavity.
  6. Make a note of how the wires are connected to the element before disconnecting them. You can do this by taking a photo or making a note on a piece of paper.
  7. Disconnect the wires from the element by pulling gently on the connectors. You can now remove the old element and set it aside.
  8. You can now reattach the wires to your replacement element and screw the element back into place. Replace the backplate and secure it. Put the shelves and shelf racks back into the oven cavity and reattach the door, remembering to clip the hinges back into place.

Replace the Thermostat

If your oven does switch on and heat up, but just not to the correct temperature, it means that your thermostat is broken and will need to be replaced. You can do this yourself, and all you’ll need is a set of screwdrivers and a new thermostat to replace the old one with.

How to Fix It

  1. Disconnect your oven from its power supply to ensure you don’t electrocute yourself.
  2. Remove the door to make removing the oven easier. You can do this by unclipping the hinges on the door, closing the door about halfway, and pulling the door away from the oven.
  3. Remove the shelves from inside the oven to stop them from falling out when you move the oven.
  4. Unscrew the screws that are keeping the oven in place, as you’ll need to remove the oven from its frame to access the back. These screws can be found by opening the oven door and looking around the oven cavity’s rim.
  5. Once you’ve removed the screws, you can slide the oven out onto a sturdy surface nearby. You might need to ask someone to help you with this, as the oven can be quite heavy.
  6. Unclip the capillary tube at the very back of the oven cavity.
  7. Unscrew and remove the oven’s top panel. Remember to make a note of how the wires are connected to the thermostat for later reference.
  8. Gently pull the capillary tube out through the roof of the oven.
  9. Remove the temperature control knob at the oven’s front, using a flathead screwdriver to pry it away from the oven gently.
  10. Unscrew the screws that are holding the thermostat in place from the front of the oven.
  11. Now you can simply pull the thermostat out and disconnect the electrical wires.
  12. Install the new thermostat by threading the capillary tube back into the oven cavity and clipping it in place.
  13. Reconnect the electrical wires to the new thermostat in the same order that you removed them, put the thermostat back into place and screw it in to secure it, and then replace the temperature control knob.
  14. Screw the top panel back into place, replace the shelves and reattach the door. Make sure you clip the hinges back into place to secure the door properly.
