Atwood Water heater help
I have an Atwood Gas Water heater model number G6A-7E in a 1994 Fleetwood motorhome. It is the basic 6 gal DSI
The water heater has always worked well until now. I searched the forum and read some other Atwood problems posted here.
It just started giving problems this week. The water heater would start and come on and work after a few try’s. Then it would work sometimes, now it does not work at all. I am now getting the lock out red light.
Here is what I have done so far. I checked for 12 volt and have good voltage 13.4 to the thermostat with the switch on. I blew out the tubes good with air. I disconnected and clean all the grounds connections. I checked all the other wires and made sure the connections were clean and solid. I also sprayed electrical cleaner on the connections to the control board. The thermal disconnect wire is good.
I removed the little thermostat and ECO. They both show continuity when checked at the terminals. I don’t know if that is how you check them to see if they are good or not?
Is there a way I can check the control board to see if it is good?
Is there a sequence to checking and tracking to see where the problem is?
Is there anything else I can check?
Would I have 12 volt at the thermostat if the control board was bad?
What do you think?
