Hi!Most likely the situation is that you need a magnatron. This is what heats everything in the microwave. What you need to do is check your owner's manual to see if the magnatron is covered under warranty. If it is, you can call an authorized servicer to make the repairs under warranty.If you have any questions, please post them here. If not, please click accept. If you are satisfied, please leave me feedback so that I know how I am doing. Thank you!
