So I had a problem in the middle of July 4th weekend, and I had to call the HVAC guy to get my HVAC running with a house full of folks. He said that he had to replace a transformer, and that my control board was not sending the signal for the fan to come on. He replaced the transformer, and then he jumped the fan so that he could have the fan run 24/7. It has been working.
I know that I need a new control board. My control board is a honeywell 9160 control board. I went to supplyhouse and bought a universal honeywell 9120 board. Here is a picture of my current board:
I can see that the cool tab is not on there any more. My thought is that he wired the cool jumper to some constant power source to get the fan to come on. I was trying to see what are the ways to get constant power to the cool wire going to the fan(hi) to make it stay on?
Any help would be appreciated.
I have mapped out all the other wires for the board swap based on what came with the universal board.
