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

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.

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.

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.
