Dometic 3313189.000

Just replaced my old control board with dometic 3313189.000 due to having airconditioner problems. Turned out the board was problem so I replaced it. Now, when I switch my thermostat to furnace, the furnace relay starts buzzing, furnace fan kicks on and relay still buzzes with no ignition. I am new to all this travel trailer stuff and would appreciate any help. Thanks

    1. Always post Year Brand Model of RV
    2. ALWAYS post model of appliance (Dometic AC model)
    3. Post TYPE of wall tstat. Dometic has almost 8 different models.
    4. We will assume the Single zone tstat with just 3 wires to the tstat. Correct? That is the tstat that your control board uses.
    5. I will bet you have not connected the wires at the new control board correctly. The 2 blue/white wires go to the furnace. Doug
