Micro panel does not start oven

R-9H84B - May 29, 2017

I would suggest pulling the control board out and looking on the foil side (opposite the component side) for "ring cracks," most likely on the low voltage transformer's connections.

The board may have the screen-printed reference designator "T1" near the low voltage transformer.




Also be sure the fuse is not easy to turn with your fingertips when it is in the holder. If it is, the fuse holder is too loose and must be replaced (not just squeezed with pliers).

You can order a fuse holder, part number WB06X10034 for $6.49 (subject to change) from the Pros here.

If you have any keypad issues, please note that the membrane keypads for this model have long been discontinued.

i think your getting to much moisture in your microwave the exhaust fan is to small and can't handle it. once everything dries out you are able to rest it check with samsung.

HI.oven has a small DC motor thats turns the turnatable..Now if turntable does not rotate then yuo need to remove the bottom cover of the oven..Unscrew it and check if motor is working ..You can check continuity of the motor using a MULTITESTER..If it is short-circuited or not.Hope this helps.FAN and turntable is being run by this DC motor..Hope this helps.

I have the same problem, diagnosed as bad touch screen panel.

IS GREEN LIGHT IS ON BEHIND LCD ? ANY LCD NEEDS BACKLIGHT TO DISPLAY. JUST LOOK OUT FOR FUSED BACKLIGHT. LET THE DOOR OPEN OR CLOSE THE DISPLAY SHOULD BE ON.

Sounds like you should get estimates and turn in on homeowners insurance. Power surges are very destructive and you have lost the control board at least and maybe some switches. Eric

According to the owner's manual for model KHMS155L:

To Lock/Unlock Control: The microwave oven and Timer must
be off. Touch and hold START for 5 seconds until 2 tones sound and a lock icon appears on the display. Repeat to unlock and remove the lock icon from display.

This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

This can be caused by slamming the door or by habitually opening the door while it's cooking without hitting the Stop pad first.
