GE Spacemaker II clock not working (1994)

My parents have had a couple of the spacemaker microwaves mounted over the range with the built-in vent. Over time, the seal on the control board gets a crack in it and the steam from cooking below it gets up into the control board and does it in.
Even if yours isn't mounted over the range, it sounds like a main control board failure.

Sounds like your losing power, have you tried it on a completely Different circuit??? Either that or bad fuse or connections inside of microwave.

i have a ge 1800 model and it cooks fine but after awhile it shuts down and in about a hour it comes back on and ask you to set the clock.....

sounds like magnetron issue I am working on now see free fix article, how to fix a ge spacemaker microwave by prayhumbley on e-how.com

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

The first step is to set the clock. To do this, push clock, set the time using the key pad and then PUSH clock a second time.

Once that is done you can set the timer by pushing timer, putting in the number of minutes you want and pushing start.

There's a simple fix for this. Unplug the unit. Take off the top grill with 2 screws. Remove the 1 screw that holds the touch pad unit. Lift up on touchpad unit and lift out. Put a piece of aluminum foil inside a large zip lock bag and tape it to the back of the touchpad unit and reassemble. GE put the magnetron to close to the control board causing stray microwaves to interfere with the board. The foil shields it.

You can get the manual here.

But usually you just press the clock button to set

Good Luck and Please Rate Fixya!

I would contact GE Customer Service here.

If you give them your model number, they should be able to give you the model number and nearest dealer for a comparable replacement.
