I had a manual thermostat (old) and just replaced it with a Digital Ritetemp 6022(new). The reason I replaced the old with the new, was because I noticed that the AC unit was on outside and the Fan inside was not blowing(sometimes). After replacing old with new; I still have the same problem. Note I can go to the new and switch the Fan from Auto to Manual and then back to Auto and this will turn Fan on. Not sure why this is happening. Any feedback would be appreciated.
