A loose door, repeated clicking, or intermittent operation can indicate a damaged latch body or switch holder. The housing aligns the safety switches with the door hooks and helps prevent operation while the door is open. First inspect the latch opening, door alignment, mounting tabs, and switches to identify every damaged component. Match the replacement to the microwaves full model number and verify what the assembly includes. Unplugging does not remove the high-voltage capacitor hazard, so professional service is recommended.

The black door seal on the inside is leaking. Hot air and grease seep through the small holes. Then on the outside it looks like grease splatters, but it cannot be cleaned.

Microwave started to lose power intermittently. Slamming door would make it flicker on and off. Banged with my hand and went off for good. Checked power cord, fuse on board all OK. Pulled door switch mount and checked all switches on mount. All good. Filter ass'y board? Does this board pass AC or DC to control board? Thanks
Chris Boyle Profile
Hello Robert, Thank you for the question. If you tested both the switches and fuse with a multimeter and they tested good, the PC Board, PartSelect Number PS16221444 could be faulty. We hope this helps!

When we try to use it it will blow out the circuit breaker

Remove vent cover then remove touch screen control panel. When you remove control panel take photo of where everything is plugged in then unplug and remove control panel. 3 door switches located next to door in a plastic chassis. Test each switch with current tester. Remove the bad switch and replace with the new one. You tube DIY helped.

First thing I dir was search YouTube for any related videos and found this one https://www.youtube.com/watch?v=uHj4H9Fdxrc, it was the exact problem my microwave was exhibiting. Once I verified the problem by troubleshooting, I removed the part and verified that the switches were working fine, the door latch assembly showed signs of wear which was the cause of the problem. After receiving the replacement part I installed it, verified that power was restored to the unit and reassembled the microwave, works fine, hope it lasts a long time!

The diagnosis is about an hour. Coz, I need to open the control panel, got a tester, and trsted all critical parts inside the panel.
Also, replaced the fuse just to make sure its a new one. Found out it was a switch (bottom part) that control the open/close of the microwave door.

When found out the problem, the rest of t he work is easy.
