MW72 Microwave - Instructions

I ordered a microwave cooking tray from PartSelect; userfriendly site; and within two days, my part was delievered and easily installed. Thank you PartSelect!

replace new tray with no tools needed

none

Took out broken piece
Called GE Parts to order replacement
Upon arrival, opened package, took out new part, inserted it where old part had been.

Opened the microwave door and put the new plate on the carousel. Duh!

I ordered on tuesday right before Thanksgiving and was sick my tray plate broke with a house full of company comming for the holiday and no microwave low and behold i ordered on tuesday and it was at my door on wednesday what a shock i will forever be a loyal customer thanks part select!!!

Just placed the new tray in the microwave. Simple as that.

It was easy. went to GE website and click onto parts replacement. Placed my order and within three business days the new glass tray arrived. How easy was that....

First I removed upper front grill by removing two Philips head screws on top and pulling off. This exposed the Philips head screw which holds control panel in place. After removing screw I pushed up on panel and it came off to expose fuse. With needle nose pliers I removed old fuse and again with pliers held new fuse in position. With the help of a bladed screwdriver, I pushed new fuse into holder, then replaced panel, screw and grill. This took less than 15 minutes even as one of the wires on control panel pulled out of connection and took some time to locate where to reconnect, otherwise was an easy fix
.

Removed control panel, discharged HV capacitor. Removed old diode, tested to confirm failure. Replaced part. Other than the removal of the panel swapping the part was almost as easy as replacing a light bulb.

Jenn-Air Microwave would not turn on. Clock worked , light worked, timer worked and would count down .I changed' Part #0813140 Switch, Micr} cost $8.99 plus shippingNow it works Thank You for good advise

I removed the outer cover and exposed the inner workings. I watched a video on partselect.com to show how to remove and replace the Diode. I followed the instructions and it was very easy to replace.

Unfortunately, the diode was only part of the issue. I ended up replacing the High Voltage capacitor and Magnetron also. Those were a little more complicated but still easy to do.

Now the Microwave works just like new! Cost me less than $100 for all parts.

The high voltage tired was shorted. I replaced it with a new one, but that did not solve the problem.

You can test the high voltage tired with a voltmeter and a 9 V battery. Search Search for it on YouTube.

You can also test the high voltage capacitor, the high-voltage transformer, and the magnetron with a multi meter. Search for the procedures on YouTube.

I tested all these high-voltage components with a low-voltage multi meter, and they all checked out OK (after replacing the diode). However the microwave still did not heat food.

When working on a microwave it is important to unplug it and also discharge the high voltage capacitor. The capacitor has a 10 megaohm resister to automatically discharge itself, but it may have failed – – so discharge it manually.

In the end I ordered a new microwave.

I mistakenly thought I had to remove the microwave to get to the back, not so. I would have had access to what I needed to unscrew; but I have to admit the hassle of taking it down and putting it back equals having to work on it attached to the shelf-your call on how you do this. I unscrewed the front top to remove the vent piece that is across the top front of the microwave. This will reveal the control panel screw. (While you have the vent removed you might want to clean the vent and the exposed filter.) carefully lift and pull out control panel. I unplugged a piece as the wires were tied tight. It will not completely detach, so carefully tip it back from exposed insides. The fuse is not clear but white with silver ends so look in upper right for it. I popped it out and replaced it. Replugged the wired part to cover and carefully fit tabs in and slide down to secre. Replace screw, replace vent piece and secure screws on top of microwave. I plugged it in to test before putting it back above my stove.

Removed 4 small star head screws from back of microwave, lifted body off, removed blown fuse and replaced with new one (found where cord enters). This model is stainless inside and out and I like it a lot. It is also sold by Daewoo and a few other manufacturers.
