ATWOOD OVEN TROUBLESHOOTING ?

Try replacing the thermalcouple first. If that does not do it, then replace the gas valve assembly. Thats the only two possibilities.

Thanks Don. May I ask is the thermacouple or gas valve hard to replace?

..

Don in looking further the burner will light if I blow on the pilot area gently though does not stay lit. Can we eliminate the thermacouple as the pilot always stays lit? Gas valve? All the stove top burners work find so can I asume the LP regulator is OKay? I apreciate your help. Think I can replace the valve if that is the problem.

Based on your comments, I would have to say it is likely pilot flame not large enough. First I would take the pilot orifice out and soak it in cleaner. As I remember alcohol (rubbing not drinking) or brake cleaner should work. Let it soak for a few hours. You can also remove the pilot gas tube from the oven valve and with the orifice out, gently blow the line out using compressed air. Reinstal everything being careful to check for gas leaks at the joints. Light the pilot and check to be sure the thermalcouple is solidly in the pilot flame. Remember you can remove the steel plate over the burner for better access. On mine, I lift the front off two pins push back against a couple of springs and lift off the rear pins. Let me(us) know how it comes out.

Sounds good. I am now soaking the orphis and will blow out the pilot line carefully. Then will reasemble and report back. Thanks for helpin me on this one

Good Luck !

Well I am stumped. I cleaned out the pilot orphas & line. Cleaned out the burner asembly. Put it all back together and it still acts the same as before. Pilot lights great and stays lit. Larger blue flame appears by the pilot when heat is turned up but hesitates to light unless I gently blow on the area. Then burner lights, flickers and goes out. As I said previous all other propane works well. Could it be pressure regulator? Would thermacouple be bad? Any thoughts?

Put a shop rag under the burner area and wash the whole assembly with carburetor cleaner. That stuff will melt the carbon that insulates the thermocouple after a few years. I have fixed three of them this way!

OK Bob, if Scotts suggestion does not cure the problem, I guess your last shot is a new gas valve and thermalcouple. Are you absolutely positive the pilot flame is getting the thermalcouple hot enough to open the gas valve?
