Thank you.

No problem. If the microwave still looks and sounds like it's working, but it's just not heating--that means your magnetron has likely failed. The magnetron is the part that actually creates the microwave to heat the food and it commonly goes bad and rarely gives a warning. The part itself costs about $100 so depending on the condition of the microwave and whether you can fix it yourself or not, it may be better to just replace the microwave rather than repair it. Also, it will require you to un-install the entire microwave and remove the outer shell in order to access the magnetron for replacement so if you called a technician out it would be another $150-200 for trip and labor. Below is a link to the magnetron you'd need to order and replace for your model number.

Thank you Tyler. I really appreciate the information. It's a combination wall unit so it definitely won't be cheaper to replace the microwave. Just knowing the part and how much a repair will cost is extremely valuable. Thank you again!

No problem and I wish you only the best. I'm sorry about the bad news however.
