We have a Carrier AC/Heat pump. We have been having a problem with the 5amp fuse that is located on the inside unit. When the heat or ac tries to engage it blows the fuse. We have checked the board and found a spot where two thermostat wires were touching and shorting out on the outside case cover. Thought we had it resolved and even cleaned the board on the outside unit. When we turned the heat back on it turned on great and then when it got to the correct temp inside it turned off. When it came back on it again blew the fuse. We had run out of solutions. Anyone have any ideas? The fan runs fine and the emergency heat also works properly. Help!
