Microwave oven (broken but fixable) (Bowers x El Camino)

At first the fan kept on blowing and the carousel kept turning after the heating time ended, as long as the door was open. I used this for a while after making sure the oven was not still beaming out microwaves with the door open.

And then the keypad stopped responding, and the heating stopped.

Some research suggest that this may be a problem with some switches

Otherwise, microwave is in fine condition. The photo does not do it justice. The keypad had the original plastic on the entire time, so underneath it is still in clean condition..

Please acKnowledge in your request that you know this microwave is nonfunctional. And propose a time frame are confident you can come, because once I put this out, I do not want to have to bring it back in.
