MH6140XFQ1 Whirlpool Microwave - Instructions

Husband replaced the bulb

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, 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.

Simply removed two screws to remove the old vent grille and replaced it with the new grille. I was also very pleased with the assistance I received from the service rep. I had ordered the wrong grille. I called the PartSelect help number and the rep walked me through the product return process, then found the correct part and ordered it. I had the replace 3 - 4 days later. The rep was very polite and patient during the whole process.

Looked up the Whirlpool Co. and ordered the part. It was quite simple. Arrived in 2 days and I simply placed it in the microware. It was very very easy!

First, we had to clean up all the interior surfaces, which was just cleaning. There was no internal damage. Then, just setting the center connector, rotary rollers and glass plate. Simple

Bought a new one. Perfect match, easy replacement.

Took out turntable and swapped out old one with a new bright and shiny
New one, ring that is. It was easy using the part from parts select
Thanks

It took me time to remove the parts and suss out the issue, but the repair itself was EASY. A wire ribbon connected to the circuit board had gone bad. One Phillips head screwdriver, 7 screws, to get at the old one, pull it out, replace it with the newly ordered part. NO PROBLEM. Ladies, you can do IT!! You have the power!

Unscrewed 4 different screws, replaced the vent & returned screws. Ack to original positions

removed perimeter screws from the bottom side and the lower cover is hinged at the wall side. Motor is visible and easily removed with two screws. Take of the old one, install the new one, and reverse the procedure to put the bottom cover back in place. Will nee helper to hold one side of the bottom until couple of screws can be put in on the other side.

Didn't realize this part had two tabs with reinforced screwholes in it. Those obviously had snapped off at some time in the distant past, and I had always removed the grille for cleaning carefully and washed it by hand and replaced it. The clean freak moved in and took this out WEEKLY and all the other tabs were eventually cracked and made the grille unusable; it kept rattling and falling out. When I got the replacement I noticed the broken tabs and replaced the item in a few minutes after removing the debris of five or six tabs and finding a Philips head screwdriver for the apparent screws (in fine shape, they were!) and tab remnants. Good fit, looks like new. Now hopefully the clean freak won't find my screwdriver next week.

It took me 15 minutes total - 5 minutes to clean the microwave, 1 minute to install three new parts, and 9 minutes to enjoy my celebratory glass of wine!
