Pilot goes out when dialed back to on
no I dont think you have a mother board. If there wasone it would be in a box of some sort on the top or right near the top mounted on the side.
If you replaced the coupler, I would say the gas valve is bad. Go to you local supply store and get a new valve. you should have 3 connection on the valve, the main gas feed and the main burner and your coupler.
Make sure you turn off the water at the main, drain it all down and when you have all the connection moved get a large channel lock or pipe wrench and turn the valve counter clock wise use tape or dope on the section that goes into the tank and tighten it up, hook up your other pipes and test for gas leak with soap and water.
Make sure when you buy the valve you get a match to the kind of gas you have natural or L P one will not work with the other.
OH check for gas leaks
Best of luck Tom

The pilot is ok.the main burner does not come on
First check and see if the dial on the gas valve is on the ON position. Next turn the thermostat up all the way.if it does not come on then, this sounds crazy, but, tap the gas valve twice lightly with the back end of a screw driver, sometimes a spec of dirt can clog the gas valve and this releases it. if it still doesnt come on, you need a Volt Ohms meter or multi meter, set the meter to millivolts, you want to connect the 2 leads from the meter to the terminals on the gas valve that the 2 wires from the pilot generator, located next to the main burner underneath tank. turn the meter on and the millivolts should read a minimum of 400 milivolts, if lower, replace pilot generator. If still doesnt work, replace gas valve.

Hi, I have an old Atwood gas water heater (model
That is not a model number that sounds familiar. Should be a tag on side of water heater behind cover, outside. If it has the little arm adjustment for temperature on top of gas valve, simply move it over a little to the left to increase water temperature, and try it until temperature is what you are happy with.
I'm assuming when you say it goes out completely that the pilot remains on and water heater re-lights when called for? If you adjust that temperature lever over, and water still doesn't get hot, you need to replace gas control, as thermostat is built in to it.
