Take your time, and look for how-to videos on youtube. I saved about $200 by fixing it myself.

microwave - some controls and clock not functioning properly

torx screwdriver

The built-in microwave is very heavy so getting it in and out of the kitchen cabinetry was the most difficult part. Open the door and remove two torx screws on either side that hold the microwave to the cabinet. On my model, these same screws also hold a trim piece in place so be careful that these don't drop to the floor when the screws come out and get damaged. Once it was out, using the same torx bit screwdriver to remove the top cover was easy (8 small screws) and it revealed easy access to the circuit boards. The old boards are clipped in place so using your fingers or a screwdriver to unseat the boards from the plastic fingers was easy, along with unplugging the wiring, no tools needed. Just make sure you unplug the wiring by pulling on the hard plastic plug section of the plug, not on the wiring itself, and don't touch the electronics on the board until all the wiring is unplugged. I believe static electricity could damage any other boards that are in the microwave. While making sure not to touch the electronics on the boards with your fingers, clipping the new boards in place and plugging in the wiring is even easier. But the new boards arrived all connected together like one big board and it took me a moment to realize that i needed to break them apart as well as break off some small excess pieces of the board. At first i thought i was sent the incorrect board because it's much bigger than the old board. I had never broken a board apart before and was unsure at first but it's designed this way. Breaking the boards apart and breaking off the excess pieces seemed like i was doing something wrong, as it made a bad snapping cracking sound. Here again, I avoided touching the electronics on the boards with my fingers. It felt risky to do every time i snapped it but again, it's designed this way. After everything was in place, I rechecked all the wiring connections, placed the cover on top, and plugged in the microwave for a test. Everything worked great. I screwed the cover in place and while lifting it and placing it back into the cabinet, I asked my wife to plug in the power cord inside the cabinet and make sure the cord isn't getting pinched or sitting under the heavy microwave in the cabinet. Open the door and put the four screws back in place. With my model's extra trim pieces, it was a little more fiddly to make sure the trim pieces were straight and with consistent gaps. Now the microwave works as intended.
