Came home from work to find no AC. I checked the thermostat and the display was blank. After replacing the batteries and resetting the program, my AC unit never started up.
I checked: - The AC unit (Carrier) outside to see if the fans was spinning, but it was not. It does appear to move freely when I pushed/spun it. - The breaker downstairs, it was fine. Still I flipped it on-off-on. - The tech switch on the side of furnace was on, still I flipped that on-off-on. - The fan does come on, but only blows ambient temperature air. - When I set the thermostat (White-Rogers) Off, then to Cool. The cool message blinks for a while. - I moved the Y wire to the RC terminal, but nothing happens.
I just moved into this house, and AC was working fine for the past 3 months.
