Looked up symptoms on parts select website. Ordered mag and diode. Very easy to take micro off the wall. Easily removed screws holding the skin on. Found diode. Really didn't need to replace it but since I had a new one (fairly cheap), just did so. Diode only installs one way. Can't botch it HOWEVER, MAKE SURE THE ONLY PART OF THE D ... Read more IODE TO TOUCH THE GROUNDING POLE IS THE SCREW DOWN LEAD. IF THE OPPOSITE END LEAD, THAT WHICH IS THE PUSH ON TERMINAL, TOUCHES THE GROUNDING POLE, YOU'LL GET ARCHY SPARKY. The magnetron goes in very easy. Simply pay attention to how you removed it and reverse that process installing the new one. There are easy to use YouTube videos that show magnetron replacement. You can do this easily and save your microwave and $$ while doing so.

The replacement turntable we received was an exact duplicate of the original. It was as easy as rinsing the new turntable, taking the old turntable out and putting the new one in.

Remove “over the stove” unit. Remove unit shell case. Unscrew and disconnect diode. Replace diode. Re-assemble. Put unit back in place.

Ordered a new one, put it in place in less than one minute.

We bought a really nice microwave for about 1/3rd of the MSRP, but it was an open box item and when we got it home we found that it was missing a bracket on the inside of the microwave. We were able to replace the bracket easily thanks to partselect.com.

Should be about 1 5/8 inch with 3/8 inch prongs. Sent bulb won’t fit.

Set the new one inside the microwave

Part arrived in timely manner and placed it in microwave oven.

The part is pushed against the ceiling into an opening and then turned 90 degree. That is is.

PartSelect website indicated replacing the high voltage power supply diode is the solution for "no heat" 99% of the time, but the diode was OK. There is more info at the website concerning the case of "loud buzzing and no heat" indicating the magnetron needs to be replaced. As an electrical engineer with knowledge of microwave components, ... Read more this was also my best guess. However, getting to the magnetron is not the easiest job, but it's not impossible. You also have to be careful to bleed off any charge stored on the high voltage power supply capacitor. Luckily, I found my KitchenAid service manual tucked away inside the unit since I couldn't find it online.

Just put it in

Fool proof.

Ordered the part and was extremely pleased with how quickly it shipped and also the packaging was extremely secure. Will definitely purchase from this site again.
