Ge WB27X10860 Pwb(Pcb) Asm Sub OEM Part

GE Advantium 120 microwave/convection oven, manufactured March 2008. Worked great every day for 14 years. Then the display flickered and bounced all over. Replaced the digitron. No joy. The keypad also stopped working and the appliance only hummed when power was restored (no matter how long the circuit breaker was turned off). Then nothing worked at all. Replaced the power board, the two power board sub-assemblies, the relay board, and the transformer (after 14 years, I figured if two or more major electronic parts failed, the others were likely to do so in the near future). The unit still looks brand new inside and out, and now works like it again for a fraction of the cost of replacing it (which would have been a waste) or paying someone to repair it.

I researched the symptoms here. The info was very helpful. It was not 100% clear which part was at fault, so I picked the top 3. (I did not want to do this several times). I replaced the 3 boards, being careful to note which cable went where by labeling connectors. Reassembled. Plugged in to test. All was good. Reinstalled unit. Plugging the cord in while putting the microwave back in place was the “hardest” part. The unit is back working, just like brand new. The components I received were all new OEM parts in original packaging. .

REPLACEMENT. OF THE DIGITRON FIXED THE DIM DISPLAY. REPLACEMENT. OF POWER BOARD FIXED THE FLASHING OF DIGITRON.
