Active Vent opens and closes continuously while unit is idle

"Active Vent" door opens and closes continuously when the unit is idle. This is a narrow panel along the top of the face of the unit, hinged at the bottom. It normally opens automatically during just about every operation, and closes at the end. It worked fine until about 6 months ago. Unplugging for a while does not clear it, nor does turning the fan on & off or any other normal operation. Random selections on the touch panel eventually clears it, but so far we have not identified a pattern. Is there some sort of reset sequence used by service personnel?

    I have the same problem. Were you able to find a solution?

  • jmangers Aug 13, 2010

    No solution yet, but here is a potential "band-aid":
    When the microwave finishes cooking, before you open the door, press the Off button twice while the vent is closing. Wait for the vent to close. Then listen carefully, and if you hear a ticking noise, go ahead and press Off two more times. Then open the door and remove the food.

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 -->

JVM3670sk6 mircowave over the range, vent door continues to open and shut when oven is off


It may need a reset. You can do that by unplugging the power for a minute or two, then plugging it back in and setting the clock.

If it still fails, you may have a failing sensor switch in the vent fan / louver assembly or a damaged component.

There should be a technical sheet hidden behind the grille or behinds the controls. It's very handy to locate and test components.

You can find a video here that shows you how to remove the grille & controller in about 5 minutes.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

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.

Venting of microwave - house stinks of bacon


Interesting post, because I have the same problem! I have spent the better part of today researching and taking our microwave apart (partially) to inspect the top portion re: outside vent. Everytime the microwave is on, the "active vent door" (manufacturer's term, not mine!) opens. Apparently this is normal. But it also opens when you turn on the vent fan, when cooking on the stovetop. I don't like this feature, because I think it 'overrides' the outside venting system. I double checked our outside vent to ensure that when this oven was installed, the person did in fact allow the flap to be open when the fan is on (he did). So I think what 'our' problem is, is that the microwave active vent sort of interferes with the outside vent, thus more of the cooking smell being blown into the house instead of the outdoors. I was thinking of simply disconnecting the gizmo that make the active vent door open each time you use the oven and/or vent fan option however I don't think that's a good idea as apparently the main purpose of the active vent door is to keep the electronics of the microwave oven from overheating. The more I read about this version of microwave, the less impressed I am with it. Lots of electronic issues with it. I am not fussy either with having the microwave over the cooktop. Sorry I don't have a solution for your problem but I do feel your pain!!!

My Dacor DMT2420 fan, light and turtable motor run continuously when the door is open. I have unplugged the unit to reset it with no help, another on-line forum expert suggested checking the door switches...


If the cooling fan, light and turntable run continuously when the door is open, but not when it is closed, your secondary interlock (bottom door switch) is shorted (always on).

Even if it's shorted, the actuator button (usually red) will still move up and down when you open and close the door.

It will need a new door switch.

See the service manual here. See our file on door switches here.

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.

GE Spacemaker xl1800


A simple test is to place a piece of bread in the microwave ( it heats up very fast) and then if your microwave was actually ON and generating RF, the bread would get hot very fast.. If it remains cool then only the fan is on. It appears that you may have a faulty door switch thou because once you open the door, your microwave should be off..

Are you sure the VENT is not on? That blower will operate regardless of the door open or closed so you must switch it OFF.

Buzzing noise, wont work???


The magnatron is shorting, overloading the high voltage transformer. From the picture this looks like an older unit and is probably not worth a magnatron replacement.
