You probably have a shorted relay on your control board. I regularly repair these for $54.95, which includes insured return shipping.

Contact me directly for more info.

It is possible that the magnatron is bad but hard to say on a no heat problem without checking all components. A lot of model give 5-7 yr warranty on that part.

SOURCE: when I open my microwave door, it starts running

.
In most cases, it's not actually cooking, but instead the fan, turtable and light may be on. Yet it does need attention.

What this usually means is that you have a shorted door switch or a bad door switch mount.

It's easy to tell if it's actually cooking, just place a cup of water inside and see if it heats.

If so, that could mean a stuck relay on the control board. If so, we repair these for customers nationwide with our guaranteed $39.95 service. Far less than a new board.

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and
disassembly information at our site, linked here on Fixya: http://tinyurl.com/yzjozk

Please write back with more details if you need further help.

SOURCE: GE Advantium 120 Microwave fan stays on, off only when door open

Looking at the schematic in the service manual here, I would say relay RY6 on the small sub PCB (relay board) has shorted contacts.

That's the relay that runs both the fan and turntable.

It's possible that it may be a bad connection or driving component on that board, but in my experience, it's virtually always a stuck relay.

The part number on the relay as shown in the photo is hard to read, but it looks like "OJ-SH-112LM".

I should have one of these or I can point you to one if you want to contact me with the exact number.

Feel free to contact me directly (and please remind me of your full model number) for more information & help.

SOURCE: fan in microwave won't shut off

in most cases, it is the door switch. It usually has 2 micro switches and either one can go bad. Not a hard fix. I would look at the operation to see if the switches are working. If that is not it, could be in the circuit board. Could be too much to fix, maybe buy a new one if it is a counter top type. Otherwise let it run till it quits. Call a repair guy, and have him diagnose the problem. Tell him you will fix it in a month or two so could he write down what you need with the part numbers. This way you do not have to start at ground zero. Then order the parts and fix yourself if you feel brave enough.

OTR Samsung Microwave fan comes on with no reason. Any way to fix it?


Does this happen while you are cooking on the range burners under the control panel?? These type microwaves have a heat sensor built into them in the area of the control panel bottom. If the microwave control gets too hot from cooking on the stove below it the heat sensor will turn the fan on to keep the control panel from getting heat damage. The fan should go off after everything cools off.

Why is the microwave running without being turned on?


These above range microwaves "hoods" automatically turn on a cooling fan even when the microwave is not in use. If you read the manuals you will see warnings about the fans automatically starting. Even when the microwave is not in use opening the door likely interrupts the power to the automatic cooling fan.

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.
