Normal causes for that would be by-pass valve not in proper position, or defective, allowing cold to mix with hot, or thermostat not touching up against tank properly, or defective. Do you know where that thermostat is?
Look where the black foam cover is, with white letters, below pressure relief valve. One is lettered ECO, other THERM. If you note where the wires go, so as not to mix them up , and pull them off, then peel back the foam cover, you'll see 2 little round discs, that are held against the tank by a small spring. They need to be checked that they are in there properly and are up against the aluminum tank.

If it has the little thermal cut-off in power wire to thermostat (has a little plastic jacket over it) try removing it, and connect female spade from power wire, directly to male spade on thermostat, and see what happens. Also, make sure electrode is positioned in flame good for flame sensing properly.

Very simple, do you have a 12 volt light tester, or multimeter?
First thing to try is to remove the thermal cut-off from circuit and try it. That's the little diode like thing inside the plastic sleeve below pressure relief valve. Remove it from the circuit and hook female spade from end, directly to thermostat where other end was before. If that does it, replace thermal cut-off.
If not, start testing for 12 volts when trying to ignite, from one side of thermostat, then over to ECO, or just go directly to gas control connection. If 12 volts getting to gas control, thermostat and ECO are o.k.
Are you getting spark at electrode?

The yellow is caused because the flame does not have enough oxygen. Per your explanation that is being caused because the exaust is not working. Fix the exaust problem and it probably will begin opperating properly.

I am looking for a troubleshooting procedure for an Atwood G6a-8E RV water heater. Unit has electronic ignition and does not want to ignite.

I have an Atwood G6A-8E water heater. It stopped working last year so I took it to Camping Wprld. Their R&I'd the tube and igniter. He cleaned to tube and adjusted the igniter. The water heater...

Have you verified that you have 12 Volts DC to gas valve when it is trying to ignite? If you have the little thermal cut-off ( looks like a small diode ) inside plastic sleeve going to terminal on thermostat, remove it and connect female end on that brown wire directly to thermostat terminal and see if it lights.If it does, get a new thermal cut-off. It's a safety device so don"t go without it. It shuts off gas to valve if there is a flame up.

Have an G6A-8E Atwood water heater. It Starts fine and shuts down after a couple of seconds. I can see the diode in the control board continue to spark after ignition I replaced the igniter.

If it has the little thermal cut-off in power wire to thermostat (has a little plastic jacket over it) try removing it, and connect female spade from power wire, directly to male spade on thermostat, and see what happens. Also, make sure electrode is positioned in flame good for flame sensing properly.
