House A/C fan running backwards.?
A/C has been running off and on all day with no problem then it just kept running and getting warmer in the house. There is no airflow coming from the vents at all. I checked the flex pipe and it is fine. what I did find was that the squirrel cage fan is running backwards. Air is coming out of the center of it. What would make the fan do that all of a sudden? What do I need to replace?
