My air conditioner quit on us last night and its really hot here in Arizona. We have a Carrier Weathermaker 8000 and the problem we are having is with the blower not coming on.
So far, we have replaced the thermostat, performed the self diagnostic test on the furnace (the blower did come on during the test), and replaced the filter (it was changed 2 months ago). Nothing can make the blower come on.
The Air conditioner fan does turn on and one of the pipes going to our home has frost on it. The AC fan does come on but the furnace just wont blow any of the cold air. Also, there is a click sound that comes from the thermostat, followed by a loud humming noise. Normally, the blower would come on about 10 to 20 seconds after the humming noise started. There is no change if I switch the air from Auto to On. The temperature in the room is 84 and we have turned the air down to 77 yet it wont come on.
We appreciate any assistance in getting this solved.
