atwood water heater
My water heater works fine on electricity. But when switching to propane, the ignitor lights the propane and it runs for about 10 seconds and then goes out. It tries this three times and then locks out. I have removed the connectors to the board and cleaned them ,as well as removing ignitor ,adjusting gap and cleaning it as well. I had this same issue at the start of last year but it all of a sudden it started working. Should I be replacing the circuit board, ignitor or both ? Any ideas
