JVM1490 Low fan noise when not in use shuts off when door is open turns back on when door is closed?

    My GE JVM1490 also makes a low fan noise when I close the door and the oven (microwave/convection) is not on. WIth the door open - the fan goes off and the light comes on. When you close the door, the light goes out and the low fan comes on - it is a different fan, not the hood fan.

    I have the same oven and it developed the same problem. I disassembled the unit and traced the noise to the damper motor which controls both an intake and exhaust damper on the oven chamber (not to be confused with the exhaust hood of this unit). I have not been able to figure out yet whether the damper motor needs replacing or whether it is a control panel issue. I did take the motor out of the oven and test it separately and it turns but when I put a load against the arm that connects it to the exhaust damper control rod it does not offer much force and continues to run if I hold that arm stationary.

It sounds as if your door switch is out of line. If this only happens when you close the door you may want to check they switches on the inside. one of them is either bad or you just may need to line it back up.

How do I get my emerson microwave to turn off after the timer is finished?

There are a couple of microwave ovens out there where after it has finished cooking, the light and fan continue to run until you open the door. Then the fans shuts off, but the light remains on. When you close the door, then the light shuts off. If the light and fan go back on when you close the door, then you have a bad door switch.

Samsung model smh7178std, shut the door and the fan and lights come on automatically, if i lift up on the door the fan shuts off but light stays on.

some switches are normally closed "short position" press switch "open" it will be labeled NC on the one side, "stands for normally closed" and others will be NO "stands for normally open" press switch "short" if there is no change in readings when you press switch it is defective.

When the microvave in plugged into outlet it makes a buzzing sound but works ok. When the door in opened the noise stops but starts back up when door is closed.

I just had the same problem with my ge spacemaker microwave model number JVM1490bd. I removed the grill on the top of the microwave with two screws on top. There is one screw that holds the front touch pad on, remove the screw and lift up to remove. The damper assembly is on the upper left, my door was sticking and didn't make the limit switch. I moved the door back and forth making the switch a couple times and that solved the problem.

I own a GE profile spacemaker jvm1490. When the door is closed there is a running noise. It stops if the door is pulled slightly. It also makes this noise when the microwave is in cook or reheat mode. ...

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are working.

You may have a shorted cooling fan relay on the control circuit board.

We regularly repair these control units for customers nationwide by mail for $39.95 postpaid with a one-year guarantee.

Or you can order a whole new control circuit board (smart board) here.

Feel free to contact me directly (and please include your full model number from the tag in or on the unit) for a free estimate and free tips & do-it-yourself advice.

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

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.
