MW86 Microwave - Instructions

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.

Ordered a new door frame morning of March 25.
Part arrived the next morning and by that afternoon, the
replacement was complete. Only four screws held the frame.

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 met ... Read more er. 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 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 w ... Read more ere a little more complicated but still easy to do.

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

Just pulled the old support out with pliers and installed the new one which snaps in. Not sure why the support melted as it has been the same one twice now. Keep extra support clips on hand, but no need as Parts Select had the new ones here next day.

I didn't. Don't know how to get to light bulb to change it for this specific model

Snipped four corners off inspection panel,removed one phillips screw and two elect. Connections. Reverse process.

I was really delighted that parts are still offered for this model microwave oven, also know as "time master"

The plastic plunger broke and as long as I had it apart I replaced all plastic pieces associated with the door handle assembly. The door handle had plastic forms for the screws to go into. these plastic forms were also ... Read more cracked and unusable.

The problem was all due to old brittle plastic failing. The repair was easy and was completed in no time.

removed seven screws to take door apart and replace button. Glad that you still had the part for a 25-year-old unit.

Before ordering any parts I remembered seeing a fan above the nylon roof of the microwave. I had seen a belt that drove it on a prior repair 3 years ago.

I then removed 1 screw holding the electrical panel so I could tilt it open. Since power was still plugged in I didn't put my hand in. I used a flashlight and the broken bel ... Read more t.

I could also see the moter that turned the belt and tested it by starting and stopping the microwave and could see the motor pulley spin when it slowed to a stop. I then closed the control panel and screwed it in place.

That confirmed I proceded to go to the internet with the model # for the rane/microwave and looked for parts.

I had an easy job looking the part and saw that the fan as I had called it was named Stirrer because it kept stirring the microwaves over the food.

Overall I looked at 2 venders and chose Part Select because they showed the same catalog page and part numbers, and they had a better price.

I had my part/ belt in 4 working days and installed the new belt in about 15 minutes. This time unplugging the range so there was no power to be concerned with. It was a matter of picking out the old belt and putting the new belt on the motor then walking the belt over the large pulley at the Stirrer since the belt will stretch a bit.

Buttoned it up and later tested with popcorn and it left only a small amount of old maids.

Thanks, Walt
