the fuse on the control board keeps blowing and cannot find the problem


CHECK FOR A SHORT SUCH AS A WIRE TOUCHING ANOTHER WIRE OR THE BOARD TOUCHING METAL. MAKE SURE FUSE IS CORRECT AMP. ALSO TURN POWER OFF AT THE OUTDOOR UNIT AND CHECK TO MAKE SURE THERMOSTAT WIRES ARE NOT TOUCHING. IF NONE OF THESE SUGGESTIONS WORK THEN CHANGE YOUR THERMOSTAT. THIS SHOULD SOLVE YOUR PROBLEM.
