Me and my Dad removed a 3 ton air handler and condensor Trane 2 stage inside and out 2007 from his home and put it in my house. We hooked up everything the same but the board lights in the air handler won't turn on and the unit is acting dead???? I changed the board inside the transformer is getting 230v and putting out 26 volts all connections look tight but still won't turn on? It was blowing cold at his home. Can this be due to the TCONT 802 digital t stat anyone have the wiring diagram for this?? I have never seen anything like this before please help desperate woman here in New Orleans.

white? is it an automotive style fuse or a round glass type fuse but white? If it is automotive, it is wrong. It should be a 3 or 5 amp and should be pink or brown. What is the voltage between R and C @ the LVTB?
I have to go bak into the 7 layers of hell in the attic on the 3rd floor. Here is a pic of the fuse It was put in new yesterday.

You need a digital meter, check across both wires/connectors for 24 volts.

Or if you remove the stat cover you can check there as well, across R and C or R and any of the other terminals. R will be the 24 volts coming from the control board in the furnace. If it's there than it's good at the board.

The furnace door switch needs to be in to provide power to the board which in turn provides power everywhere else, so have the doors on.
