SOURCE: Microwave works with door open

If the top is open, the upper door switch should be open and the high voltage section should not be energized. That's the way it's *supposed* to work. But that buzzing is worrysome! Does the turntable turn during this condition? Does the inside light come on? How about the fan? If not, then I would doubt that it's cooking. If so, some models will do this. It's not uncommon to notice that the fan and light will try to come on for a split second when you shut the door. This would not indicate a problem. It has to do with the timing of the door switches and a replay on the board. If it's still under full warranty, it wouldn't hurt to call a GE-authorized servicer.

There may be an option to turn that off with the keypad, but your best bet would be to contact Jenn-Air.

The manual will have their contact info or you can see: http://www.jennair.com/content.jsp?name=contact_us

If it goes dead or blows the breaker or GFI when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. Other times, it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

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

There may also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

SOURCE: 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.

SOURCE: 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 -->
