Atwood stove burner valves

The valves are completely different parts with different part numbers, typically--with a bigger orifice on the center valve and maybe some other differences as well.

I would suspect that the valve isn't the problem, but rather a (partly) blocked air hole in the burner tube, or something misaligned, or a clog in the tube itself, or something similar. Opening the top of the stove and doing some basic checking and cleaning of things would likely restore proper operation. You probably won't need to do anything to the valve or its orifice.

OK DrewE, Thanks for the quick response, always better to do the easy things first. I will take it apart and clean it up and see if that fixes it. I was thinking that based on the outward appearance of the valve assembly that the internals of the valves were all the same. I have a regular output valve that was replaced and was thinking that if the orifice was different or the same I would swap them and see what happens. Hopefully the cleaning will be the easy way to solve the problem.

Thanks again

Cleaning will fix it. A bit of trash in the tube slows the flow so it doesn’t draw enough air. Could even be a spider web.

Hello guys,
I finally had time just now to take the burner off the stove top. I cleaned the inside of the burner tube by running a wad of paper through it and took the plate off the top of the burner (two small screws)and wiped the inside of the burner clean. The early result is that the flame is not nearly as orange as it was with just a little orange at the flame tips. some run time will show what happens.

Thanks again for the help guys, Bob
