I'd used the house air conditioning few days recently and set thermostat high not to run it. Last night, I found that the outside air conditioning cooling fan had kept running over hours even if I set the air conditoning off and set fan off from the thermostat. I heard a minor sissing air noise at the air conditoning unit, not the cooling fan. It seemed the air conditoning unit was doing something.
I was afraid of burning the cooling fan moter off and turned off its power from the central power box in the basement. Now the cooling fan is stopped running. It's 2 years old house, and this is the first time it happened.
Could you adive me what to do with it?
