A 2 yr old could do this snap out. Snap in less then. 30 seconds . What a shame and rip off on appliance repair shops - I called to do this rediculsley 40 second job and the wantvv$125.00!9t more. Omg. I’m a senior/ no wonder God punished the world wit Covid 19! Too many nasty infair. Buii I needed and rip offs.

Replaced all 3 switches and Holder for all 3 switches. All is working great now.

Disassembly control panel and remove switch holder; test for micro switches for continuity. Holder had broken post on micro switch holder.

When removing a non-working door switch, you will see a hooked piece of plastic on the holder locker that looks like a latch. If you try to pull it back in order to either remove the bad switch or install a good one, it will likely break. Instead, you need to pivot the switch (It pivots on a little post which is fitted into a hole at the corner of the switch) out of position so that it is not held back by the 'latch'. Then lift the switch out. If you have to use lots of force anything, you're doing something wrong. Reverse all this when installing the new switch.

Unfortunately the filter upgrade for my microwave was not a fit. When I tried it in my microwave my microwave did not work. I thought I was going to have to have a repairman come and check what was wrong. I decided to put the original filter back in and when I did my microwave worked fine. Select Parts Has issued me a refund for the purchase I made that did not work. I am at present still researching for a filter that work for my microwave.

Unscrewed two screws above, replaced grille and screws.

Need a Phillips screwdriver for screws. Screws MUST be removed in order to side the new grille into the brackets.

I went for the cheap things first. Ohmmeter showed one of the thermostats in the magnetron compartment was open. I ordered and replaced all three thermostats. Still no heat. I took the unit off the wall (aaarrgh!) and checked the oven cavity thermal cutout. It said 7 ohms. I tested by shorting the wires together, but still no heat. So, I ordered the magnetron and diode cable. When replacing the diode cable (be sure to discharge the big cap!) either I broke it, or it was already damaged. It came off in two pieces. The new diode cable was re-enforced with thick heat shrink tubing, to prevent such breaking. You need a very short screwdriver to replace the magnetron. Now, all fixed! ~$150. A new one lists for $2000, installed in the overhead. My wife thinks I am a genius.

The hardest part was removing/reinstalling the microwave from under the kitchen cabinets, but once that was accomplished the repair went very easy. The motor/fan assy was easily accessed once the microwave outer cabinet was removed and the part was even better than the original, with a stop on the motor shaft to insure proper reinstalling of the fan blade.

Went on Youtube and pulled up how to fix a microwave.
