Turn table wouldn't turn in my microwave.
This was no big deal. Just inserted the new gadget under the turntable. It beginning turning as soon as I pressed start on the microwave.

What I was impressed with, is that I ordered it on line, and within two days my part was sitting on my front porch. I was very happy about the delivery. I live in a remote area, and didn't expect it for a week. Thank you.

coupler under plate in microwave broken
We ordered part from store where we bought the microwave. We waited a week and the part was not the right one. I found the part I needed at your company. I received the part the next day. I just inserted the coupler in the hole where the other one was and fixed the problem imediately. We will buy all our parts here from now on.

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.

Appears to work, but food not heated
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.

Microwave would continue to run even when door was open. (even if no time was left on timer)
Unplugged Microwave, Removed vent cover (2 screws on top of microwave, then slide cover to the left, then forward) Removed control panel (1 screw at top of panel) then removed the two screws that hold in the door switch assembly. (these you will only see by opening the microwave). Located lower door switch, removed connecting wires, and pulled switch by releasing small plastic tab which held it in. Put new switch in place, reconnected wires, then reconnected door switch assembly. Reconnected control panel, and then put the vent cover back on. Tested microwave and it no longer runs when the door is open. Super easy fix, and was done in under 5 minutes.

I picked up a used microwave that came with the needed mounting plate but no screws
Based on my research, this over the range miscrowave should have come with 2 templates: 1 for the wall and 1 for the underside of the wall cabinet. The challenge was to measure every very aspect of that microwave in order to obtain placement specs for the mounting screws. Tip: I made the holes through the top cabinet bottom a little larger than needed and used big washers with then for stability to gain the most "play" in the self aligning screws. Worked out well. Took 2 tries to get the wall plate perfect so have precision in mounting that piece.

Microwave stopped working - would not heat up
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.
