    I have a ge spacemaker 1800. Everything seems to work,

    lights, turntable, same sound, but nothing heats up.

    No matter how long you put food in.

    The turntable turns, but when you put something on the table to heat it will not turn. I have changes the rollers and it still will not turn when you put something on it.

    Mine just started doing the same thing - everything works but no heat. It is a little less than 3 years old. Will check out your suggested sites and get back if I figure anything out.

    I have the same problem. That is the over seems to be working but no heat. One other thing is that when it went bad there was a smeel of burning electrical wire. Does this narrow the problem.

    My microwave is a Spacemaker 2.0. The first one stopped working at all a few month after I had it installed in my newly remodeled kitchen

    . After six repair visits, months of scheduled visits, and mediating communication between the repairman and the parts department, it was replaced. One of the repairmen said they had been having trouble with defective parts. Now, guess what? The new one stopped working...exactly two months after the warranty ran out. For $500.00 I expected a bit more. So it really only cost me about $36 a month for microwave convenience. I have always been happy with GE products but you can bet I won't buy another.

    My spacemaker stopped heating. The light and turntable still turn but there is no heat generated. The Microwave is only 2 years old. We have not had any other issues with this microwave.

    Thank you

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part

GE Profile Spacemaker XL1800 microwave turntable

The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

On some, you have to cut the motor cover off with snips, then use a screw when reassembling it.
