Atwood G6A-6E not lighting. Possible gas valve issue?
Hello all,
This will be a bit of a long post but I want to know if I covered my bases before posting.
I have a 1989 Mallard Sprinter class A. The water heater is a Atwood G6A-6E 6 gal electronic ignition wh. On a trip a couple of months ago, I noticed the wh having trouble keeping a full flame. It would cycle on, but after a while seemed to almost "choke out" but not quite.
Back at home base, I didn't turn on the wh, although I keep water in the system. I noticed during a walk around that the PRV was weeping and it had been leaking onto the main burner tube so I resolved to fix that. I bled the PRV to get an air bubble back in the tank and replaced the burner tube.
I attempted to start the wh and was rewarded with the clicking sound but no "whoof" sound like the wh ignited. There was no air in the lines as I started the furnace and stove beforehand. I have done the following: taken every connector loose, cleaned and reconnected. Cleaned the flue with a bottle brush and blew out with compressed air. Replaced the spark probe assembly because the original had some cracks in the electrodes.
I had a helper inside the mh turn the ignition switch on and off while I checked the electrical connectors outside. I had power (12v plus) to the board, wires to the eco, wires to the stat, red wires from the eco to the gas valve. the green ground I made sure was seated. At this point I am only smelling a very tiny bit of LP, barely noticable, then its gone.
Should I be able to hear the solenoid open at the gas valve? A clunk or squeak maybe? I dunno what else to consider at this point and I don't want to spend $500 replacing parts until the problem works itself out.
I think I've covered most of the bases but if I didn't write it down, let me know
Thanks in advance and if this post needs to be moved, go for it
