Atwood water heater--older manual pilot only. Pilot lights fine, holds flame in ON position. just can't get the burner to fire. First attempt this season. Of course I was counting on it for a hot shower since I'm getting plumbing work done in the house at the moment.

I would guess spider webs in the burner tube. I once had a similar problem turned out to be a lady bug carcase.

I have the same problem sometimes. The pilot tries to light the burner and then it goes back out
Clean all wire connections on the outside.
My unit says on a decal to clean all wire connections, before replacing the circuit board.
I am still think of trying a dielectric grease on them.

In the original poster's case, the thermocouple has nothing to do with whether or not the main burner will light. He says he has a manual pilot, in which case, the thermocouple is a safety for the pilot only.

There is some kind of problem with the main burner itself,or possibly the gas valve.In some cases, the main burner valve can stick, and giving the main burner control a rap with a screwdriver handle may free it up temporarily. Try this, and if the main burner lights, take the trailer to a service department, and get the burner control replaced.

Glad I came back here. Found 18" thermocouple--way too long. Got too late Saturday to exchange. If your confident that the thermocouple is not the issue, I will return it and seek professional help. As for good news, the plumber finished up in the house--had hot shower by Saturday night! New 3/4" PEX lines feeding whole house. Just got washer and dryer both fired up for the first time since I moved into my "Little Cabin In The Woods" here in Faucett back in October. Life is good!!

When replacing a thermocouple,it is always best to replace the old one with one of the same length. Longer is not better,but will probably work alright in a pinch.

If your manual pilot is staying lit, the thermocouple is functioning correctly.
