Central Ac Indoor Blower Motor Section
My Central ac system is about 10 yrs old and has been maintained by professionals, since I purchased the home 3 yrs ago. However, I don't want to have my home warranty involved unless I need to for the $75 service fee.
The problem just started the last week or so during the central ac cycle and I never noticed the problem during the winter and heater use. My central ac thermostat is set on 69 degrees (happens on 68 or 70 too), my blower motor will run for a few hours and then will shut off for approx. 5 seconds then back on and off within 5-10 seconds then will run for minutes or hours while still blowing cold air.
During one time that the blower shut off I went outside and noticed that the outside unit fan was still working and when the blower came back on the air was still cold. When I went in the attic to look at the system, I noticed that a section on the unit was sweating quite a bit.
I changed the batteries in the thermostat last night and it still did it. Any ideas of the problem before I contact my home warranty company? I am mechanically inclined.
