Atwood-Dometic water heater igniter board
Some other brand 5th wheel, Atwood-Dometic 6gal water-heater 120vac/propane, 2018 model but used full time for 1.5 years.
model number GC6AA-10E
The short version is this... I have only 9.2v from the igniter board to the various wire connections that lead to the solenoid, and the solenoid does not "click" open... though some propane gets through when it efforts to ignite.
The sparker doesn't spark, but a flick-a-bic will ignite what little propane gets past the solenoid during the ignition effort. But the propane will shut off after the failed ignition sequence.
The Atwood trouble shooting guide says it needs a minimum of 10.5v to work properly. I measured the voltage from the wire harness going into the igniter board. It was either 12.4 or 13.4, I don't remember which, but it seems to me it was the full battery voltage.
It would seem to me that the igniter board is failing to pass along 10.5-12+v to the thermal fuse, thermostats, and solenoid... but I would have thought it would just outright fail rather than deliver a substandard 9.2v.
Before I spend $120 on a new igniter board, I thought I would ask for your thoughts and ideas.
Thanks in advance
