John October 31, 2021 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?
1 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.

Alvin August 06, 2020 for Model Number FFMV062LQA I need to know which door switch is normally open, and which is normally closed
1 Answer John, I couldn't find your model number but most models are the same. Primary Switch and Door Sensing Switch are normally open, and the Monitor Switch is normally closed. Again on most models, the Monitor Switch is the one in the middle. Hope this helps! Read More...
Joe April 08, 2020 for Model Number LFMV164QFA Fuse trips when we open the door while the microwave is on, not when the microwave is off. I have read that this os often caused by door switches. Which part do I need to order to replace the door switch? are they brand name, generic switches, or both available? Thank you
1 Answer Joe, The parts that you would want to get for the door switches will be 2 of part number 5304509460, one for the top and one for the bottom. You will also want to get the door switch part number 5304509459 for the middle switch. Read More...
Steve December 06, 2019 FPBM3077RFB Microhood, touch panel not working. Started out intermittently, but could push buttons when door was open but when door closed, panel no longer worked. Now it doesn't work at all except the clock is lit up just fine. I suspect I need to replace the pc board in the door, but could it be the control board?
1 Answer Hello Steve, This sounds more like either a harness issue or a connection issue. I would first check the connections on each end of the harness and, if no problem is located, you can check the harness with an ohmmeter. The wiring should show the same reading on the meter as when the meter leads are touched directly together. If any discrepancy is found, replace the harness. Read More...
Mickey November 30, 2019 for Model Number LFMV1645TF microwave blows fuse when opening door. How can you tell which switch is the culprit. 5304509459 or 5304509460 (x2)? will work for a while when replacing fuse.
1 Answer Mickey, The correct test would be a continuity test with the switches in there home position. You will want to see a change from open to closed or reverse when the door is opened or closed. When we say open or closed we are referring to the switch having continuity or not. You always need to change all three switches at the same time. Read More...
Barbara June 14, 2019 My Frigidaire microwave model # FPBM3077RFA will not start unless I slam the door several times. It works OK after it seems to connect.
1 Answer Hello Barbara, You either have a failing door switch, (two 5304509460 and one 5304509459), or the latch hook 5304509457 screws are loose and the assembly holding the switches is able to move around. You will need to remove the air grille and then the control panel to access the door switch assembly. Read More...
Annie February 12, 2019 for Model Number FMV152KQA My unit does not turn on when you simply close the door and press the start button or a easy set button. If you open and close the door multiple time, it works. Also pressing the door firmly, near the top door latch seems to make it work too? Do I need to replace the door switch?
1 Answer Annie, You will want to check the door switch on the unit to ensure it is good. Also check the door latch on the unit to make sure that it is making good contact with the switches. Read More...
