I had a local Atwood dealer check the board. The only tester they had was an old school Dinosaur board tester. The guy said it may or may not work with my style board. They hooked it up and got the gas valve and ignitor to operate on the tester. However it is still not working on the RV. It still works great and electric mode but not gas. I am still getting 12 volts to the orange wire going into the board but no power going to the gas valve or ECO switch
Did you check........do you have DC on the BROWN wires ???
Without THAT circuit getting 12V DC then the RED wires to ECO/Gas valve and Spark Electrode will NEVER get DC Voltage-----
Gas Switch ON
DC to circuit board via ORANGE 1
DC from circuit board to thermal fuse/t-stat BROWN 1 then back to circuit board via BROWN 3
DC from circuit board to ECO/Gas Valve via RED 4 (for 6-8 seconds while DC is sent to Spark Electrode)
