Hi, welcome to Just Answer. Sorry to hear you are having appliance trouble, I know how frustrating that can be! My name is ***** ***** I look forward to helping you!
Does it sound the same as it has when it was working or does it make any strange noises or run with no noise as the timer counts down?
If it sounds the same and is not heating at all, the magnetron has failed. This is not something you will be able to fix tonight. This is also a high voltage repair, it can be dangerous to complete. Are you familiar with electricity and comfortable with that?
Usually, the part takes about a week to get, so if you can get someone out right away, you will be down for about 10-12 days. You may want to invest in a small counter top model for the time it is down, they are pretty inexpensive if you get a very basic, low end model.
