    I put two new delivery fans in as follows: Brown PS1, PS2; Green R1.2, 2.2; White +1; Gray -1.

    I hope I didn't screw something up. At first I had the white + and gray - wires reversed. I measure 24 volts at the white and gray terminals and the voltage on the other terminals seems to vary with the potentiometers OK. No shorts across motor, resistors are 1.75K ohm.

    Does anyone know how to troubleshoot this?

    Thanks so much and have a Happy New Year everyone.
