I am selling my house and have run into a problem. I don't want to turn off the electric but I also don't want to run the A/C. The thermostats highest temp is 90 so as long as its 90 and over in the house, the A/C will always call for cooling. So I set the temp to 90, pulled the breaker next to the outside condenser and flipped the A/C breakers off at the circuit breaker box. Now the fan continually stays on because the A/C is calling for cooling. I don't want it to continually run and burn out or catch on fire. Does anyone know how to turn that fan off? The digital generic DR Horton thermostat only has Heat, cool and OF (whatever that means but I am pretty certain it does not mean off because the fan keeps running).

There should be another breaker outside that will turn off the air handler in your attic. The fan shouldn't keep running with the system off though. I had a similar problem several years back when I tried to replace a thermostat without powering down the system. I blew a transformer in the air handler and the furnace fan kept running even with the thermostat set 'off'. The result was a couple hundred bucks and a learning lesson. If you can't find the correct breaker, I think most air handlers simply 'plug in' in the attic. If you can stomach the heat, you can go up and unplug it from the outlet.

I will probably have to go into the attic and unplug it. A person would have thought there would be a better way. Thanks for the tip!

In the curcuit breaker panel, there should be a breaker labeled "Furnace," "Air Handler," or "A/H." Flipping this breaker to the off position will kill power to the unit in your attic. Or you should be able to set your thermostat to the off position and set the fan setting to auto and it won't call for cooling or turn your fan on.

I found the air handler breaker the day after my last post of 8/1. It was labeled: A - H. I felt like the village idiot. It was no where near the AC breakers.

Don't feel dumb, a lot of people don't know about the A/H breaker! TwoBigDawgs, you can flip the breaker for the AC but that will just kill the power to your condensing unit (outdoor unit) not your air handler/furnace (which is located in the attic or your garage most of the time). If you want the system totally shut down you can either set the thermostat to the off position or you can kill power to the condensing unit and to the air handler/furnace in the main electrical panel.
