Hello Friends, Hope all is well
My 6 gallon Atwood propane water heater has a board problem. It has a difficult time with the spark needed to ignite the gas. The board functions otherwise as designed. I replaced the electrode without results. My Norcold board had a similar problem about a year ago and with my electronic experience I replaced ?the ignitor coil on the board and its working perfect a year later. I suspect it may be the same problem I had with the Norcold board but with that board I wasn't able to test and confirm but rather took a gamble on a $7 part that turned out to be the problem. In the Norcold case it had no spark at all but in the case of the Atwood it sparks intermittently. Most of the time it will spark near the end of the timed ignition cycle causing a pretty good bang from the accumulated propane in the chamber. I have lit it manually many times and it works perfectly when I do. I can say for sure that the flame verification is working properly. It is just the ignition.
I am looking for any test specifications for the Atwood control board. I am aware of the complexity of getting to the components on the board due to the fact that the board is sealed in silicone but I have successfully tackled that before.
Thanks everyone
Henry
