Your primary interlock (bottom door switch) is probably shorted, or its mount is damaged or misaligned, keeping it in the "on" position.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually 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. 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 should 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.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you only need a switch, you can order a universal type here for $5 postpaid.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

I'd be AWFULLY NERVOUS about that - you don't know if the magnetron is also generating microwaves. If it IS, it can give you cataracts and/or blind you.

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 microwave won't turn off


Just checked the GE website. Had the same problem with my 5 year old microwave. GE website says to close and open the door quickly three times. First time I did this it didn't work. Second time I closed the door with some significant force and reopened it more quickly. Worked. Unplugged the microwave, plugged it back in, still fine.

Humming ge sapcesaver microwave


During operation, most of the built-in models have a panel that tilts out while the exhaust fan is on. When cooking is done, the exhaust fan shuts off and the panel retracts to its normal position. With the fan & microwave motor off, the hum is easier to hear. Look closely at the top panel the next time you hear the hum, and you'll probably see that it's retracting.

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.

Microwave seems to turn on when door latch is opened


What's happening is you are activating one door switch a little before the other, and that is causing your light, fan, and turntable to come on. The plastic parts are not perfectly rigid, so they flex a little when you press the button, and that causes the lag to be more apparent. Even if you press the door open faster and look really close, you may notice the light, fan, and turntable coming on for a split second. That's perfectly normal. The relay on the control board must also be turned on before it will actually be cooking.
