Turn the t-stat off. Open it so where you see the winding connections. Unscrew the red connection and don't let it touch anything for about 3 minutes and put it back turn the tstat back on to auto and cool that will reset the thermostat oh and check the batteries

If you have a thermometer that measures down to 0 to 20 degrees, take the temp at the closes vent to the air handler. Should be around 40 degrees. If you unhook the Y or C from the thermostat and turn the air handler back on, does it start running again?

Explain why you have to take the red t-stat wire off of the subase when the stat is off ? when Just moving it to the off position will break the 24 v.
