The fan on my Trane outside air conditioning unit is always running. The house stays nice and cool but the fan doesn't turn off even when I turn off the a/c. The only way to stop it is when I flip off the power at the breaker box.
When the a/c is off the fan spins but not too fast, it does goes fast when the a/c is running.
Anyone else see this problem before? Any suggestions on how to self fix or do I need a repairman?
Your queries reflect that you are NOT taking the initiative to do Google and YouTube research. Pretty much 2 types of internet users . . searchers and slackers. The latter tend to seek out others to exploit with endless questions.
Might start with an advanced search on trane.com . . example.
While I didn't do I search on contactor's, I have been doing extensive searches during the last two weeks trying to find others with a similiar problem. I have only seen the fan always running problem in one or two other places so I guess it isn't very common. Hopefully once I have it fixed, I can document everything and it will be easier for others later.
It doesn't always mean it's the contactor. You could have a compressor problem where it cuts off and the contactor is staying closed because the thermostat is still calling for cooling. Compressors have overloads which cut out the compressor at 71% of the locked rotor amperage. I know you said it doesn't cut off even when you cut off the unit. Just a heads up.

Yes. You should hear a slight hum from the compressor and the air coming off the unit should be warmer than the ambient air entering it. If it's a multiple stage unit it will increase fan speeds to compensate for the compressor kicking into higher speeds. If the air coming off the top or side of the unit (side meaning a unit like a ductless mini-split) is the same temperature that's going into it either the inside air temp is extremely cold or the compressor isn't running.
