Question about GE Profile Spacemaker Over-the-Range Microwave

1 Answer

Microwave light and fan run all the time will not shut off When I close the door, the fan comes on and the light stays on, never shuts off. Does not seem to be putting out the microwaves, as a cup of water doesn't get heated and the the vent above does not open as it does when I use it. Does heat when I enter the time/power as normal. GE model PVM1870DMICC Tried unplugging it for a few minutes, enough to require a clock set, but no difference.

    After a few months, the problem cleared up by itself!

    The light is out, I wonder if that fixed it? ;-)

That is probably a bad primary interlock (bottom door switch).

See this file for help on checking and replacing door switches.

There should 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.

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.

Fan & Light stays on???


On a few new model microwave ovens, this is a "feature"! It's purpose is to cool the microwave parts down, and to remind you that your food is cooked. Once you open the door, the fan will shut off and stay off when you close the door again. But if not, or if you microwave oven didn't use to do this, 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.

GE Spacesaver microwave always runs when the door is shut


I see this all the time. In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

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.

Our Microwave keeps running unless we give it a whack!


Hi firstly to see if it is producing energy, buy some 5mm light emitting diodes from an electronics store. cut off the leads close to the plastic body.
place in microwave and put on cook for max 10 secs, if the led's light up you have microwave energy, shut off the oven as soon as they glow otherwise you end up with a mess.
If you have energy then your problem is most probably the door interlock micro switches which after time do not operate properly. let me know the results and we can go further.
