GE Spacemaker XL1800 - Automatic Fan

I used my oven for the first time today. The heat rising up under my new Spacemaker triggered the automatic fan. The owner's manual says it should go off automatically after about 30 min. It's now 3 hours later - there's no heat to speak of - and the fan is still running. Meanwhile, I'm unable to use the microwave at all anymore.

Re: GE Spacemaker XL1800 - Automatic Fan

Hopefully steam didn't get up into it. Apparently it was the heat, but it may be miswired or have a defect in the hood thermostat or on the controller. I always recommend using the hood fan when cooking on the stove top or in the oven but that may have been irrelevant here. I would definitely recommend calling the GE Answer Center at 1-800-626-2005 on this one. If the installation was done correctly, then an exchange may be in order. Early in the warranty, you should be very demanding!

My ge spacemaker xl1800 light and fan turn on when door is opened. small piece of foil does not spark during this. is there an easy fix?

Kent, most microwaves will turn on the light when you open the door. As for the fan coming on, does it do that all of the time or only after you have used it for a period of time? If it does only after you have used it, you might want to check the back and the underneath of your microwave to see where the fan draws air into the unit and clean any lint built up on the vent holes. Hope this helps!

Ge spacemaker xl1800 vent fan

I'm betting your base model number is JVM1860, JVM1861, JVM1870, JVM1871, JVM3660, or JVM3670.
That's the automatic louver you're having trouble with. There are micro switches in the louver assembly which tell the controller when the louver is open or closed.
If one of those switches or the louver motor fails, the louver will not work correctly.
Did your cooktop lights recently fail?
Sometimes the surge from them shorting will cause damage to the circuit board, which can be repaired.
There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.
There is a video here showing how to remove a typical over the range control panel assembly in under 5 minutes.
You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

I have a ge above range spacemaker xl1800 it seems to work fine except their is a rattling noise when its running it sounds like a bad fan or something comeing loose it seems like its comeing from under...

The noise you are hearing is due to the fan. The fan is used to cool the magnetron during cooking, and because this fan is not working the magnetron is overheating and the thermal protector is opening, killing power to the unit. All you need to fix this is a new fan blade. The fan blade(look for part #80) is slipping on the motor shaft ( the noise you are hearing).

If the blade is broken then you can buy a new one from---


Please ask for further clarifications.
