    Good afternoon,
    I’m writing as a follow-up to my purchase of the control board for my RUDD air handler. My experience may be of interest to others with a similar situation. The control board has two connections marked W1 and W2. Terminal W1 is a white/black wire that is connected to the relay (factory installed). It also has a purple wire that is not connected to anything. Terminal W2 has a white/blue wire that the AC installers connected to the white wire from the thermostat.
    The heater has never worked on this unit. The fan would come on, but the heater elements did not energize. If I jumped 24V directly to the relay, the heaters would come on. With the thermostat set to ‘heat’, I had 24V between W2 (white/blue wire) and common. But I did not have 24V across the relay. I assumed the circuit board was supposed to close a connection between W1 and W2 and that is why I bought a new circuit board from you. I installed the new circuit board and had exactly the same situation. The chances that both the original circuit board and the one I bought from you were both defective seems like a long shot.

    I changed the wiring by connecting the white wire from the thermostat to the white/black wire going directly to the relay. Heater works fine now. I could not find a specific wiring diagram for connecting the thermostat wires for this handler, so my ‘work around’ was mostly trial and error and a little deduction.
    Hope your new year is off to a good start.
    Regards,
    David
