Question about Air Conditioners
This may be somewhat difficult depending on the year make and model. I will try to help without this knowledge.
There are 2 sides to the transformer. Read the label to see which is which. One side is labeled 24 volt and the other side is labeled 115 volt.
The 115v side will probably only have 2 wires. A white wire and a black wire. The white one will connect to the common or neutral system. If there is a circuit board it will plug on to the 120v Common terminal (probably marked L2). If the air handler does not have a circuit board, the white wire will connect to the other white common wires by a wire nut.
The Black (hot) 120v wire will connect to the 120v L1 terminal on the circuit board. If there is not a circuit board, read the schematics to find out where to wire nut the black 120v wire to. It will obviously be connected to a 120v incoming hot center after the blower door switch.
The 24volt wires will connect in a similar fashion to the circuit board. T1 will connect to the 24v hot terminal on the board. The T2 will connect to the 24v common terminal. If there is not a circuit board you will need to read the schematics very carefully before proceeding. It may be a good idea to add a 2amp fuseable link on the 24v T1 wire just in the case we are wrong.
The 24v hot wire may be wired in multiple ways without a circuit board. One way is to be wired to the Limit side of the Fan/Limit switch (located on back wall of the burner compartment just above the gas valve. Another way is wired to the gas valve. Please read the schematics located on the blower door. I hope this helps at least a little. Let me know please. Thanks.
