Having problems after the microwave stop and i push the door button the lights on the display goes off and then it will not work again

Probable magnetron or control board failure

this a problem a dust in the control board keypads, You must open the keypad, and clean any connector with contact cleaner specially the ribbon cable or plastic and use pencil eraser for to fix the corrosion, dust, and try again.
God bless you

Step 1:

Door Switch

If the microwave runs for a few seconds and then shuts off, a door switch might have failed intermittently. Check each of the door switches for any signs of overheating, arcing, or burning. Also check each of them for continuity. Replace any of the switches that is visibly damaged or that only has continuity intermittently

Step 2:

Main Control Board

If the microwave runs for a few seconds and stops there may be a short circuit in the main control board. Check other components first, these boards are often misdiagnosed.

Touchpad and Control Panel

If the microwave runs for a few seconds and stops the touchpad and control panel might be defective. There are several other components that can cause this problem, be sure to check any other components before replacing this board.

Touchpad

If the microwave runs for a few seconds and stops the touchpad might be at fault. This is not common. Generally speaking, if the microwave display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.

High Voltage Transformer

If the microwave runs for a few seconds and stops the high voltage transformer might have an intermittent short. This is not common. Check other components related to the microwave symptom first.

Thermostat

If the microwave runs for a few seconds and stops the thermostat might be defective. Watch our video on testing thermostat

Step 6:

use the DVOM tester and fix it. God bless you

The drawer often stops working when it is abruptly stopped while opening and forced closed or vice-versa. To fix, simply do the following:
1) Push the draw all the way closed
2) Push the "Setup" button repeatedly until the "Open/Close ...?" appears.
3) Hold the Start Button until the time reappears in the display.
4) Repeat steps 2 & 3 three more times
5) Unplug the Microwave for 30 minutes.
The drawer is now reset. The drawer will now open electronically (automatically) either by pushing the open button on the panel or by pulling the drawer handle slightly.

hello mam
i am having the solution for this problem check the lock terminals for loose connection and if its working and check the magnetron which produses the heat inside the microwave.

There function is prevent the oven to work whit the door open
some are normally close and some normally open when one of then don’t work properly causes a short and blow the main fuse check the all and replace the faulty one but be careful and don’t test the microwave
Whit the cover removed.

Note:
if you have a blown fuse buy several emplacement fuses because my take several trays to fix the problem and you will need more than one fuse.

I left the unit unplugged over night, plugged it back in the next day and still had the same problem.

I think you've put up with enough hassle from this unit and should get another one. Intermittant flakey problems are hard (read expensive) to fix.

It is possible that the magnatron is bad but hard to say on a no heat problem without checking all components. A lot of model give 5-7 yr warranty on that part.

I have the same problem with mine!!! I spent 58 dollars to have a 6 dollar diode replaced. Now 8 months later... same prob. Replaced again myself and working fine again. Just make sure you label the wires while working on it. I didn't and it cost me 2 new fuses! Hope this helps.
