I have a Coleman AC unit and a Payne furnace. Controlled by a Honeywell thermostat. For some reason when I run the A/C for about 6 hours straight it will quit blowing anything out of the vents. All the while the Coleman unit is still running and the Payne blower is still running, but no air comes out the vents. Where could it be going? Is there a damper or something that redirects the air?
This happens 100% of the time without fail if I run it continuously for several hours. If I run it for a few hours, turn it off, then try it's fine. But after this problem starts I have to leave it off for several hours before it will blow air again. And after this problem starts it doesn't matter if I try A/C, heat or just the fan. NOTHING will blow out of the vents anything in the whole house.
Totally wierd. The air has to go somewhere. Any ideas?
