We had a new thermostat put in and a new circuit board. When we ran the A/C everything was fine. We have since turned on the "Fan" and it runs for exactly 2 minutes every hour on the hour. Could someone please tell me why? We want to have it run all the time like it did before it was "fixed". We'rehoping it's a quick fix that we can do ourselves. Thanks so much...

Pull out the tstat install instructions,, possibly another bool that tells you how to program the new tstat, you didn`t say what brand or model number of the tstat,, so it would be hard to help you without more info

I'm sorry, I forgot to supply this information.. It's a White - Rodgers programmable thermostat Model # 1F78-151 70 Series Single stage 5/2 Day Programmable. I took the batteries out and intalled new ones and reprogrammed the system today and it still does it. It will only run for 2 minutes every hour at X:45-X:47 EVERY hour... Thanks
