John for Model Number CGMV176NTF My microwave Frigidaire Galaxy blows the fuse at times when I shut the door. What is wrong and how do I repair this?
Answer John, the upper 5304509460, lower 5304509460, and middle 5304509459 door switches would need to be tested for continuity while the microwave power cord is unplugged. The middle should have continuity when the door is open and no continuity when the door is closed. The upper and lower switches would have continuity when the door is closed and no continuity when the door is open. If these test good, it would be likely that the main control 5304509637 has failed.
