RE: Atwood 6 Gallon Gas water heater
Thanks for the replies everyone, the board came from PantherRV https://pantherrvproducts.com/91367/
While writing this post I also noticed that the packet has part number 91367, dated 10/18/21 but the part I received has 93307 on it, same year. Hmmm
Anyway I have tried over the last hour running the heater, out of about 12 times it worked fine 10 times, only failing twice. Again when it fails the gas valve opens and closes in half a second, red light comes on but still runs the ignition cycle, with obviously no gas running :R.
So going from what’s been written above;
The ignitor, gap is correct and appears to be positioned correctly, sparking between itself and not the tube, and in the path of the flame. Would an ignitor cause the gas valve to open & close immediately? I might put the old one back in.
Gas valves when it has stopped pouring with rain I shall check these, is there a way to remove them? I read somewhere about taking them out to physically check the coils.
I did rewire the gas valve earths but thinking I should look at the wiring as a whole, again when not pouring, and maybe rewire back to the battery.
Batteries are charged via solar, not shore, currently 100% reading 13.5v at the board connector.
I shall make up a 12v lamp to test that theory too.
Thanks for the help so far!

Atwood 6 Gallon Gas water heater
Hi all, hoping someone might be able to help,
I have a 6 gallon Atwood gas only water heater, and the PCB died recently, it was definitely the pcb, possibly a broken track or dry-joint, twisting it slightly would bring everything to life.
So I ordered a new PCB, new wiring loom (older pcb & loom) and ignitor probe for good measure. I replaced all the above and am now left with an intermittent fault.
When turning on the heater I have a 50% chance it will ignite. It will either ignite and run or I get a clonk/clonk as the gas valve opens & closes within a millisecond, yet the ignitor continues to click for about 8 seconds before lockout.
When it works the gas valve opens, just one clonk, ignitor starts and off it goes.
I checked the red wire from the PCB which feeds the valve solenoid via the thermostat, when it works I have the 12v continuously, when it doesn’t I get the 12v for way less than a second..
The PCB I got is part number 91367, which is a replacement for the 93257 from 2005 that was installed. I wonder if I have received a faulty board, or I am missing something, like incorrect replacement.
Has anyone any thoughts or similar experience?
