It sounds like you're on the right track. 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, 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 for trip and labor. Below is a link to the magnetron you'd need to order and replace for your model number.
