Frigidaire 5304509460 Microwave Door Switch OEM Part

Check fan operation and was OK. Everything else worked except when microwave was started for a cycle. I looked around on internet and found someone had trouble with the door switches. I started to check door switches and found one shorted. I replaced both lower door switches and it took care of problem.

After doing some research the problem appeared to be the door safety switches. I ordered 3 new ones to replace all the original ones. Some minor disassembly of the microwave front was required to reach the fuse and switches. To reach the switches the control panel wires needed to be unplugged and the panel removed. After doing that replacing the switches was pretty strait forward. As of this comment the microwave has worked for 5 days without blowing the fuse so far. This has probably fixed the issue.

I ordered these parts. Found the latch was worn from use of opening and closing the door. Also replaced switches as one would stick sometimes. Put back together works like a charm. Also you don't have to remove microwave from wall to fix and while in there check fuse. Make sure to unplug before working on it.

Replace all door switches, one was bad, since the unit was apart I ordered all 3, the manufacturer has a sticker that also recommends this.

At first the microwave would occasionally trip the breaker when we opened the door early. Then one morning it would not run at all without tripping it. Took off the front panel and found the middle of the 3 door switches was sticking. Multimeter showed the switch as reading open even with button pressed. Ordered a replacement and microwave has been working great since.
