Mike September 07, 2024 for Model Number ZSC1001KSS01 Display does not work at all. Microwave works when pushing the express button (30 sec). Would this be the WB27X10856 dispaly board?
1 Answer Mike, this failure would most likely be caused by the display control WB27X10858. Read More...
Seth August 03, 2024 for Model Number PSB1201NSS01 Hello. A couple of months ago, the display on the microwave started flickering and fading, digits scrambled, eventually disappearing all together. The microwave still functioned for the most part despite this, but eventually it would freeze up and the buttons/knob wouldn't do anything. Resetting the breaker would provide a temporary fix, but eventually it would start messing up again. I bought the display/digitron (WB27X10856) and replaced it. The display is bright now, but the clock is still flickering. I don't know what to do next. I would appreciate any help. I have a multimeter and am willing to tinker with this as needed. We just can't afford a new $2k microwave. Thanks
1 Answer Seth, the power board would need to be tested at the connection CN7 for voltage from the transformer WB17X10021 (part has been discontinued). From the yellow wire at pin 1 to the black wire at pin 2, there should be 12VDC. From the white wire at pin 3 to the black wire at pin 2, there should be 19VDC. Finally, there should be 7 VDC from the red wire at pin 4 to the brown wire at pin 5. If the voltages are good, the failure would likely be in the power board WB17X10021. If the voltages are not testing good, the failure would be in the low-voltage transformer. Read More...
Ken April 19, 2024 for Model Number ZSC1001KSS01 My Advantium 120 had a flickering display which was getting worse. Buttons needed to be touched a couple of times. Micro still worked well just bad display. Then a power outage and now touch panel will not work and no lights inside. Tried all of GEs troubleshooting suggestions. Outlet has power. Checked units 20 amp fuse and it checked ok. Could this a control panel issue or another part supplying power? Thanks for any help

If the voltages are not testing good, the failure would be in the low-voltage transformer. Read More...
John April 12, 2024 for Model Number SCB1001KSS01 I am having an issue with the display on my Advantium microwave/speedcook oven. It only displays in the top two rows for about a second when a control button is pressed, then goes blank. While the oven is in use, the display flickers. The lower part of the display that shows modes (Oven Demo locked...) operates properly. While the oven is in use, the display flickers. Besides the display issue, the oven operates properly. I have run the resistance and voltage checks for the transformer and they are within spec. How should I proceed?
1 Answer John, the low-voltage transformer WB17X10021 (part has been discontinued by the manufacturer and is no longer available) would need to be tested for resistance after unplugging the power supply cord. The primary winding should measure 23.2 Ohms. Then the secondary windings would be tested from the yellow wire to the black wire for 1.5 Ohms, black wire to white wire for 5.2 Ohms, and red wire to brown wire for 1.1 Ohms. If they test well, the next step would be to verify that all wire connections at the control panel are secured properly. If the wires are secure, then it would most likely be a failure in the display control WB27X10858. Read More...
Mike January 23, 2024 for Model Number SCB1001MSS01 My GE Profile Advantium 120 operates correctly while heating for ~90 seconds and then the display starts flickering. If I clear it at that time and wait for a minute or so, I can restart heating again. If I try to cook longer, the flickering gets worse and it sometimes locks up such that I have to cycle the power to get it to work again. I installed a new digital display board (WB27X10856) to possibly correct the problem. The new board made the flickering and unstable display much worse. I re-installed the old board and it works as described above. What do you suggest I try now?
1 Answer Mike, if the blower fan WB26X10182 is operating properly, the most likely cause of failure would be the display control WB27X10858 based on the information provided. Read More...
Steve May 08, 2023 for Model Number SCB1000KBB01 Advantium 120 (SCB1000KBB01) display was faint and flickering. Replaced Wb27X10856 and WB27X10858. Display bright but displaying random characters and non-characters; displayed function instructions unreadable. Put original parts back in and now won't display anything accept the bottom row (Turn Dial, Timer, etc.). Tested resistance on WB17X10021: White-Black: 22.7; Yellow-White: 4.1; Red-Brown: 0.7. Planned to purchase WB27X10861 and WB17X10021; however, everywhere I look, WB17X10021 is out of stock and apparently discontinued by manufacturer. Are these readings too far out of tolerance requiring replacement of the transformer, and if so, are you aware of a manufacturer's substitution part number or a source for this part?
1 Answer Steve, the resistance of the transformer WB17X10021 is too far out of range and would need to be replaced. Unfortunately, as the manufacturer has discontinued this part and there has not been an approved compatible part listed by the manufacturer, we would not be able to recommend an alternative.

Jim February 08, 2023 I was having the same issues as stated. Flickering and blank display. Power reset would temporarily help. Recently I have replaced the power board WB27X10861, LV Transformer WB17x10021 and the display control board WB27x10858. After doing so my display seemed brighter but still flickered. To make things worse now the unit has no power. The light doesn't even turn on inside. Prior to the loss of power my next step was the Display board WB27x10856. Is it time to just give up?

B January 14, 2023 for Model Number SCB1001SS The display on my GE profile advantium 120 microwave oven has faded (no longer bright) and is flickering/jumping some. We can still use it but sometimes need to flip the breaker to reset it. I ordered and installed WB27X10856. When I installed it and turned the breaker back on, the screen said "turn dial" - when I turn the dial a bunch of fragmented parts of words show...I can push the button on the dial and the options button and they both beep. Eventually, I was able to turn it and push the buttons enough to get the clock set. Now, it is much brighter (so seems to have fixed the fading) but it is still flickering a bunch and is difficult to use. This flickering does not get worse or better as I turn the knob. I next ordered and installed WB27X10858 - Main Control Board - Pwb(pcb) Asm Sub and then WB17X10021 - Low Voltage Transformer. Nothing changed. Then, I replaced WB27X10861 - Power Board and everything is now working well. My question is if it safe to assume that I can put the original parts back in for the digitron WB27X10856, Main Control Board - Pwb(pcb) Asm Sub and WB17X10021 - Low Voltage Transformer as the power board appears to have been the issue? Or, do you see these other parts fail next usually? I just need some guidance here.
1 Answer B, sounds like there were multiple failures there. As one part fixed the dimness and another fixed the flickering. If old parts are placed back on and voltages are wrong it could cause damage to any new part. It would be recommended to leave it as the issue is fixed. These units have a history of multiple parts being an issue with the display. Read More...

Any ideas on what else might be wrong here? Should I take the new digitron out and put the old one back in?
1 Answer B, Thanks for the question!!! You likely have an issue with the supply to the digitron from this board WB27X10858. Checking your connection would be a great idea first. Read More...
Joe March 27, 2022 for Model Number ZSC1000KBB01 My display board dances and flickers and then stops working completely. Bought a new one from you guys (WB27X10856), installed and it worked fine for six weeks or so. Then started flickering and dancing again, but generally performs the requested function, but it will likely stop working normally again soon. I tested the transformer (WB17X10021): Ohms results: source white & black = target 23.2 - actual 22.6 (slightly low) yellow & black = target 1.5 - actual 1.5 black & white = target 5.2 - actual 5.2 red & brown = target 1.1 - actual 1.0 (slightly low) Are the two reading that are slightly low mean I should replace the transformer (WB17X10021)? Either way, should I also replace pcb WB27X10861 and/or Pwb(pcb)Asm Sub (WB27X10858)? And given the Digitron display board (WB27X10856) is failing again, should I also replace that again along with the other boards and/or transformer? In other words is the new Digitron that I installed now failing, or would it work properly with other boards and/or transformer replaced? Thanks, Joe
1 Answer Joe, It does sound like the control board will be the issue and the digitron should be good as the transformer will cause this issue. Read More...
