The controls when pressing the numbers 1, 2, &amp; 3 show 6, 7, &amp; 8, or will lock up and not allow any inputs until the microwave door is opened and and shut hard. Something broke off of the switch on the right side and we can no longer select 1, 2, or 3.
For model number NQ70M6650DS
Hello James, thank you for contacting us. Based on the description that you have provided, we would recommend checking the control board, part number PS12085936, to solve the problem. A malfunctioning control board can most probably cause this issue. We hope this helps.
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.
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

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.
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

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