WB27x10856 Digitron for my GE Microwave PSB9120SF1SS

General

I have purchased several of these and no matter where I get them from they all look the same which are not identical to my original on that I am trying to replace. But the original will actually work but just flickers. All the new ones only will make my turn wheel to the venting ductwork from the magnetron open/close over and over and over until I unplug it. The original works except you can’t see most of the time what you are trying to do, but sometimes the screen looks perfect to where you can see the time, if you are selecting “express” for 30 seconds each time you hit it to heat the food/liquid, or if you hit the “defrost”, cook, oven, etc… buttons it takes you to that selection’s screen on the display.

Brand:GE
Model Number:PSB9120SF1SS
Main Symptom: Original Digitron Display Flickering, while new replacement does nothing but make magnetron vent turn wheel open and close continuously over and over
What happens & when: see symptoms and when plugged in wall.

Figured it out. The new digitron has a different firmware than the original Power Board. Before you buy a new Digitron WB27X10856 buy the power board WB27X10861. The new Power Board will work with the new or old one you already have. But only a new Digitron will work only work with a newly purchased Power Board, but you might find out the old digitron still works and really the only problem was your Power Board.
