Atwood water heater not working

[AllenBaker]

I have a Damon Challenger with a Atwood water heater model gc6aa-9e that has no power to board. First I order a new board and had power to board but no power on red wire going to ECO. So, I send that board back and they send me a new one. After installing new board now I don't have power going to the board. I check the switch on kitchen counter and I have power on blue and purple wire. The switch is model AT91959. Anybody have any answers?????

On my atwood which is also electronic ignition. there is a connector on the inside of the coach where the coach integrates with the water heater. You should be able to find it over the water heater where access it from the inside.


I would check that connector. If you have power there it should be a simple mater of finding why it isn't getting to the control board. If you don't have power there then you have a harder problem of tracing back to the switch.

If you want hot water in the interim and can find a 12V supply near that connector and patch something in to supply the 12V and send the 12v propane/electric request.

This shows what lines need which signals.
