Flood caused control board in weather king furnace to start up but would not allow ac system to turn on. Changed control board in furnace and all worked OK. The next morning the ac turned on again as temp was set up on thermostat and at the same time the furnace also turned on. I shut the gas supply off and all is working as far as ac system comes is it possible that the thermostat is the coause. Also the ac system is pushing 58 or 60 degrees but the house takes to long to cool down.
