When I turned on my A/C for the first time yesterday it came on and after aboout 10 minutes the air flow stopped. I went outside to see if my unit was still running and it was, but no airflow. I cleaned the filter and hosed off the coils from the outside unit and still the same thing, no airflow after about 10 minutes. I put the thermostat on in just the fan mode and same thing happens, air flow for about 10 minutes then shuts down, the furnace did shut off as well. What seems to be the problem? Thanks.
