FCWM2727ABA Frigidaire Microwave Oven Combo - Instructions

PF alarm appeared on display. Noticed clicking when cord was moved. Had arced for some time and melted original block. New part slightly different. Only has 3 lugs, old one had six. Stack using washers provided. Take note of colors before disassembly. Use caution while working through access opening. The edges are sharp. Only tools needed are phillips screwdriver, deep socket for lug nuts. Nut driver optional. Hope this is helpful.

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.

I Put The New Tray In the Microwave

It was really easy just unplugged it took off the back cover changed the part out put back cover on plugged it in and the elements were working great!

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 the work is easy.

Removed the wires that I could, then terminal block. Installing the new terminal block was very easy; however the wires that arced were fused to the terminal bock screws and needed to be cut and new connectors had to be put on the wires to allow them to be reattached to the block safely.
Once all was replaced and reinstalled the oven has worked great. The length of the repair was increased because of the melted parts and having to run to the store to get the new wire connectors big enough to fit on the wires. If we were simply replacing the block and had not encountered the melted ends, it would have been a very quick and easy repair.

First problem was there are a lot of different enclosures for NUFA models. After much research, I found a video of a smaller countertop micro that had the same screw pattern as my large Gallery over the stove unit. For my micro, you remove the screws on the back, one screw on the left side, and the entire cover lifts off. I then discharged the capacitor using a pair of insulated needle nosed pliers, and took a picture so I could replug everything correctly. Then removed all of the connectors and one screw holding the board in place, and removed the old board. After that, I just did everything in reverse, and plugged it in. Voila! I was finished. It was a very simple job once I found how to access the control board. Hope this helps, and my thanks for the prompt parts delivery.

my original part arrived and it did not fit. When I called to explain the problem I was told it was the wrong part. The big problem is... Frigidaire calls the receptacle a terminal block kit as well as a terminal block kit which is a totally different part. I tried to explain that to several different folks I spoke to at your company as well as Frigidaire but I'm not sure if I got that point across. Take a look at part # 530 393 5058 and part # 530 440 9888 and you will see that they both mention terminal block kit. Hopefully the part I am getting from Frigidaire is an OEM part and will fit.

Watching the video showed an easy, unscrew and screw back on process while connecting the wires back. It was really that simple. Once it was complete (not even 10mins), plugged it back in, and its been working great since.

Took 3 panels off to get to the electric block. Replaced electrical block and put it back together. Still no change.
