My thermostat does have a heat, off, cool. I turn it on heat, heat doesn't come out, turn it on cool, cool doesn't come out. And fan runs whether it is on heat, off or cool. The outside central air doesn't come on and the pilot light on the furnace doesn't try to light. It worked last summer. I just know that when I call someone out here they will try and rip me off because Im a woman. Im trying to learn a little about it before I do that. So, the fan in the furnace runs the CA and the heat? The air was working last summer. The heat has been working all winter. I had the thermostat set on heat which it hadn't came on for a few days because it was warm enough in here. It got hot out 1 day last week, I decided to turn the ac on. I noticed after about an hour it wasn't getting cool in the house, but the fan was running, I went outside and noticed the outside unit was not going. I turned the thermostat to off and the auto/fan is always on auto. But the fan wouldn't turn off. I turned the thermostat to heat and turned it up high and the heat didn't come on, I went to garage and noticed furnace pilot light wasn't clicking like it does when trying to come on. I turned the thermostat to off and fan still ran so I turned off the fan on the outside of the furnace. Thank you for your time.
