Carrier 9200 blowing 3 amp fuse within 20 seconds of inducer blower starting. Does not blow fuse without the white wire connected. Not a wiring short, I have the thermostat wired directly to the terminals in the furnace. Not the thermostat, I have used the old one and a new one. I'm not sure where to go from here. Any help would be appreciated, it's getting cold in here.
