HVAC - Heating Ventilation Air Conditioning


this started happening at the end of last summer, i am not sure which a/c i have, but i have a carrier furnace system and a manual thermostat. the problem is everytime i set the thermostat to cool it the furnace board fuse will burn out. i have no problems with switching to off or heat.
and the fuse doesnt take a while to burn, it burns instantly. i am thinking it would be electrical, but since i dont know anything about wiring and which wire is for a/c, i am not able to tell if the wiring is loose or cut.
if any further information is required please let me know
