The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.

Let us know if the hard reset doesn't fix it.

GE Spacemaker XL1800 JVM1850CH01 vent fan won't turn on


Unplug for about 5 minutes and allow to reset. If the problem persist, you might want to try replacing the control panel (the one that have all the numbers and timers). Good Luck!

Microwave VENT fan keeps running


I would say you replaced a good hood thermostat (or "TCO" / thermal cutout) with a new thermostat of the wrong type.
The oven cavity TCO and the magnetron TCO will read zero ohms continuity when tested.
They are "normally closed" devices.
But the hood vent exhaust fan's TCO is a "normally open" TCO or thermostat, so it should read open or "infinity" on a continuity check.
If the temperature under the microwave gets too high, the hood TCO opens, which turns on the vent fan until it cools back down.
I would bet that only your fuse was blown.

GE spacemaker profile xl 1800 moving vent will not close


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.

Active Vent opens and closes continuously while unit is idle


I had GE look at the problem today (my microwave is less than a year old and under warranty). He replaced the cam louver and that seems to have fixed the problem. This is a small motor accessible by removing three screws and the active vent door. The whole visit was less than 15 minutes.<!-- from fixya rte -->

Jenn-Air Microwave vent grill opens and closes


I have this same problem occasionally. Pull the vent grill open and look for a white cam that rotates when the microwave is on. To the right of that cam, there are two gray switches. The bottom switch should have a red tab that pops out. When the vent grill opens and closes continuously, the red tab is stuck in. Take a flat screwdriver or tooth pick and push gently in on the red tab to release it. It must get stuck due to grease or dirt accumulation. Good luck.

While cleaning it the vent began to open and close and the microwave would not shut the vent down when the keypad was used to end the cycle. Now it only shows F3 on its screen when we try to set it up...


The "F3" error code means "Shorted key panel (touch pad)". The correction is to replace the key panel aka a membrane switch or a touch pad. The control panel in that case is just a plastic frame.

Exhaust fan doesn't work and blows air from top vent


Some microwaves have a adjustable fan. We have one that you can vent out the back, the back top or through the front top filters. The latter is what it sounds like you have. If you take the small back panel off and lift out the fan motor you'll see that you can place it in the direction you like.\\

Active vent keeps opening and closing though fan is off.


When the unit begins the never ending opening and closing cycle, turn the vent fan on for a few seconds and then turn the fan off. This seems to stop the active vent from opening and closing. If this is GE quality, this is the last thing that I am going to purchase. GE refrigerators are garbage and now I am having problems with a new microwave oven.

GE xl1800 active vent bulb replacement


I think the key is pulling the vent to the left.

From page 36 of the online version of the owner's manual, which also mentions the active grille's presence on some models:

Oven Light

Replace the burned-out bulb with a 120 volt, 20-watt
halogen bulb (WB36X10213), available from your
GE supplier.

To replace the oven light, first disconnect the
power at the main fuse or circuit breaker panel
or pull the plug.

Remove the top grille by taking out the screws
on top of the grille that hold it in place and
sliding the grille to the left (opening the door
makes grille removal easier).

Next, remove the light cover.

On some models, the light cover is located
in the center of the top opening. Remove the
screw that secures the light cover and lift the
cover off.

On some models, the light cover is located at the
left of the top opening. Lift the cover off.

Pinch the clips that hold the light socket in
place and lift the socket out.

Remove the bulb from the light socket by
pulling straight out. Replace with the same size
and type bulb, then replace the light socket and
cover.

Replace the grille and screws. Connect electrical
power to the oven.
