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 principle 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 supply is always on. Overtime the electrolytic capacitors in a section of the board fail or degrade to a point they the DC supply 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 measured the capacitance of each of the seven electrolytic 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. Normally, 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 resources 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.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.
Normally
you have to separate the door panels (as shown in the attached photo)
and then you'll see the previously hidden screws you need to remove.
Or you can watch a YouTube video (not a video I made) here that demonstrates how it's done.

Remove the glass table and watch the drive spindle to see if it is turning when the unit runs; just put a cup of water so the magnetron is not without load, they can be damaged otherwise.
If it doesn't turn, gently try to turn the spindle with your fingers.
If it turns manually, then the motor has failed.
If it doesn't, then some foodstuff has managed to freeze the spindle.
In the latter case, pull the plug from the wall, use some foaming cleanser (it's less wet) and try to get some under or around the spindle.
Let it soak overnight, then try to turn the spindle with your fingers again.
If it's now free, mop up and remove as much of the remaining cleanser as you can, leaving the table out, put a cup of water or preferably a bowl with more volume, in the unit, let it run for some minutes to try to dry the rest of the cleanser out.
Put the table back in to see if it will now turn.
If this doesn't work, it will be necessary to replace the motor.
Since this is a unit I don't know, I can't predict if it is a DIY project or not and the dealer may ask an unrealistic price for the replacement.

It is obvious that you do not have the part accessible locally however on the internet there is a very good reliable source at www.mwoparts.com that you can order that door through them. You will have to navigate through their menus but hey if that is what you need exactly they are the ones to go through. It would be difficult to think that in any city you could find a suitable replacement much less exact replacement for your door. It is very important in the operation of your microwave even though it has no electronic components. These people are reliable and I have used them in the past. Let me know if you need me to actually look up the actual part # for your Spacemaker. You have a good brand of product it is very serviceable and especially here. Let me know. God bless.

This
is usually caused by either a bad door switch or a loose door switch
mount, which are pretty simple problems to fix.
Even though a door
switch clicks, it may still be bad inside.
Door switch
or mount trouble is usually caused by slamming the door or by opening
the
door while it's cooking without hitting the Stop pad first.
There are
plastic mounts inside the microwave which hold the door switches and
onto which the door latches lock when you close the door.
The screws on these
mounts may be loose. If they get too loose, the switches will not be
activated properly.
Sometimes it's
a broken tab on the switch holder, allowing the switch to rotate just
out of position. This tab
can be hard to see, since it is under the
bottom edge of the switch.
If the mount is broken, it's usually more economical and
safer to add a dab or two of hot glue to the mount to secure the
switch. Let it cool for about 30 minutes before using.
One test that sometimes
helps is to
gently lift up (and/or push down) on the door or handle as you try to
start it. If it works or tries to work, then it's a door switch mount
or
door alignment issue.
If you or someone you
know decide to look
into it, we have critical information on safety, disassembly and door
switches at our site, and our link is at our listing here on
FixYa:.
You can find helpful
exploded view diagrams and order parts by entering your full model
number here.
There should also be a "mini-manual" hidden inside the unit behind the control
panel or hidden on the left side behind the grille, which is very
helpful when troubleshooting & testing.
At
our Web site, we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
If you only need a
switch, you can order a universal type here for $5 postpaid.
If you think the problem
is on the control panel, we repair these nationwide by mail
for $39.95 postpaid in most cases in about a week or so.
