Microwave will not heat
Yes those are the right parts to replace. Yes you can do it your self if you can get the service manual also. Or take pictures as you go so you can reference them. It should not be to hard.
No heat
HI, the magnetron has failed at this point. the pop you herd was from the magnetron tube. i would also check the high limit capacitor as well. it may have caused this pop as well.
I would replace the capacitor(high limit) and magnetron in this case.
The failed magnetron has been automatically confirmed by the no heating issue but, the cap may be on its way out soon.
I've got a GE Advantium 120/Model ZCS1001KSS01, the display will get lines thru it, and comes in and out of view, and will always finish its cycle. however, when you go back to use, it is dead.
The problem with your Display of your GE Microwave/Speedcooker is not the Digitron WB27X10856 display board? The flickering and ultimately failure over of the display is due to the WB27X10861 GE microwave control board which is a rebranded (LG 6871W1A417/6871W1A417A board) which GE then sells as a markup. The princple purpose of this board is to convert (i.e. rectify) AC to DC at various voltage levels needed by the rest of the microwave to run their control circuits in the microwave. A portion of the GE microwave is always on so the AC/DC supplly is always on. Overtime the electrolytic capacitors in a section of the board fail or degrade to a point they the DC suppy starts to produce ripples in the DC power supply which results in circuit board failures. These ripples produce deep spikes of voltage of 120 Hz that the other circuits are sensitive too. I just exmined a failed WB27X10861 board and measued the capacitance of each of the seven electroylic capacitors. Of the 7 capacitors, 2 had failed over time. The others 5 have degraded 10 to 15 percent but still within their design spec. The two that failed, C07 - 1000uF 25 V had a measured value of 207uF and the other C08 - 220uF had a measured value of 13uF. There was no visible bloating on either SAMWHA SG capacitor. Nomally, these capacitors are rated at 2000 hour at 85 degree C. 2000 hr is only 83 days, but since the voltage is less and the temperature is probably 40 to 50 degrees inside the capacitor these capacitors may last 10 years. They harder they work the shorter the lifespan. There are two solutions, either purchase a new replacement control board or replace the failed C07 and C08 capacitors within the failed board with better ones. You can easily buy 10,000 hour , 105 degree C rated capacitors for probably 25 cents more than 2,000 hour capacitor. Most people don't have the resouces to repair a board so buying a new board is their only solution. Don't buy a used board on ebay because a used board is probably on the verge of failure.
