The plastic door lock on my built in aeg Micromat 153E microwave has broken so the microwave door won't lock and food doesn't heat. Looked on the aeg website for a part number but it was unhelpful. Can you buy a spare lock/catch or does whole door need replacing?

Some microwave ovens make the turntable motor accessible from underneath.

If you wish to get some details; check the site linked here. Pull up older posts.....

Welcome aboard, sorry to disappoint but I have never seen any microwave display with a variable backlight.

3.4 - 3.7 kW = 3400 = 3700 Watts

You rather have a bad turntable motor or a stripped turntable coupling.

Hi,
That is not that hard to fix and you can easily buy the parts yourselfonline...

Here is a tip that will help you with the online buying...

Usually the screws are on the side behind the door so you must first open it. If your oven fits well and does not move it is possible that there are no screws.

1st: Dont listen to the so called gurus at FixYa. As the guru there was telling me that the frame was glued to the cabinet. If I would have followed his recommendation Id be buying new cabinets as well as a new mounting frame. FixYa should credit me my fee paid.
The solution: For the built-in cabinet AEG microwave oven, it is required to use the AEG mounting kit. The AEG mounting face frame uses for screws, one at each corner concealed by small black plastic caps that blend in perfectly with the contour of the mounting face frame. If you look closely towards the inside of each corner you'll see a very small slot in the cap that will allow you to put a small flat head screw driver into the slot to work the cap out. Once the four caps are removed use a phillips screw driver to remove the screws that fix the mounting face frame to the cabinet.

I'm not familiar with non-US models, but you would probably have to use needle nose pliers to pull it out.

If that won't work, you'd have to remove the outer cover of the oven, and then you can see how the door latch heads (the hook-like devices sticking out of the door) interact with the door latches and the opening mechanism.

Then you can call AEG at the number in your manual to see if they will sell replacement parts.

If you don't have the manual / IFU, then I would suggest contacting the manager at the dealership from which you purchased the oven to see if they have contact info for AEG.

To replace your latch heads, normally you have to separate the door panels (as shown in the attached photo) and then you'll see the previously hidden screws you need to remove.

Or you can watch a YouTube video (not a video I made) that demonstrates how it's done.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for maybe an hour. Then let us know if the hard reset does not fix it.

It may be a problem with a door switch or door switch mount.
