First I checked the diode and suspected it was bad but could not confirm it with my meter. Small price to pay to test. Received the part in 2 days from my order and installed the diode. No help. Finally I removed the Magnetron and found a cracked magnet. Ordered the magnetron and received it the next day. Installed it and problem solved. Spent less than $100 to repair a $300 microwave.
I have used AppliancePartsPro many times and have never been dissatisfied. Always the correct part and always a fast delivery. Prices good. Service Great.
