I turned my air on and I blew the 3 amp fuse on the bored in the furnace. When I replace the fuse I can't get anything to work now. I get a steady red light. I totally unhooked the AC unit from the furnace until I can get the furnace to work properly any more. When turn the heat on I get nothing. The light just stays a steady red. I don't even get a click or anything. Is there anything else I could have blown with the fuse that would make the furnace stop working?
