Because the megaton cost more than half the cost of a new microwave, I bought a countertop GE unit that was suppose to go into my built in cabinets. Guess what, GE says this microwave was for countertop only. So I ordered the parts and within an hour, I had my 8 year old unit working again, slid it into the mounting trim and kept the kitchen looking the way it looked after the remodel a few years ago. This was easier than I thought and the you tube videos available prevented errors in the repair. I did find the magnetron a little cheaper but delivery was 5-7 days away. I got the parts in less than 1 day from ordering from UPS. I have used Appliance Pros several times and am extremely pleased at the service. Always check for what I need here before I look elsewhere, but end up getting it here. 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
