HVAC won't start for AC unless I turn heat on first? Board going out?
Okay, so my AC/HVAC won't start unless I turn it to heat, let it run a few moments, then switch back to cold and lower temperature. It has been working for 5 hours so far now, but I'm worried, as this did this last week, but then ran for about 10 days in a row no issues. Is this the control board going out possibly? When the AC runs the air is cold, but sometimes the HVAC just doesnt come back on when it shuts off when it reaches the set temperature.
