Question about GE XL1800 1100 Watts Microwave Oven

Glass Surface Light Lens Cracks from Halogen lights use

Just installed a 2 yr old GE Spacemaker XL 1800 Micro/hood combo - Model JVM1850SH04 - mfg. Jul 2005. Had to replace the previously broken glass light lens with a new GE replacement glass -- this is tempered glass and covers the 2 halogen bulbs that are responsible for surface and night lights. The lights work - surface and dimming for night light ... but within several hours ... the glass lens broke ... in two places ... from the heat of the halogen lights. I can get replacement lens as there is lifetime replacement ... but what's to keep it from happening again? Are the halogen lights too hot? Also, when selecting the vent fan -- it starts on high, but when scrolling through to med and low ... doesn't seem to change the fan speed ... but the vent boost does kick it up a notch. What's the cause of this? Thanks

Re: Glass Surface Light Lens Cracks from Halogen lights...

The lights do get very hot, so they must be a sufficient distance from the lens. Was there an instruction sheet with the new lens? You may need to adjust the sockets upward. You might call a local GE-authorized servicer to see. Concerning the vent fan, this is a problem with the control panel assembly, which we repair nationwide for $39.95. Details are at our site, which is linked at our listing here on FixYa:

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.

Light bulb above stove under microwave hood

According to the GE manual it is a 120 v 20 watt halogen bulb, the GE product number is WB36X10213. That is the cooktop light/nightlight that would be on the stove hood. HTH!

It sounds like the main transformer has failed. It would be cheaper to replace the whole microwave than repair this one. Sorry to be the bearer of bad news. Hope this helps. Good luck.
