Fridge Not Cold On Gas

dano73 , have you determined the BTU your burner is providing? ;)

No !red,didn't check the btu's at the burner. How would I do that? I will go thru the whole thing again, now that I know the chimney is right.

Btw, i checked the lip pressure at the burner, with a borrowed manometer. This isn't rocket science folks, they're not expensive, just a tool I wouldn't buy, because I rarely need one.

Is the pressure at the burner a secret? how much drop when ya fire the stove burners?
Proper pressure and impeccably clean orifice are needed to provide proper heat.

Sorry red, my previous thread said it showed about 12 inches. I rarely use the stove so pressure drop isn't an issue in my mind., although the stove and water heater work fine, with no problems. My flame looks nice and strong, and never goes out during travel, but it starts to melt down within hours of being unplugged.

Did it always do this
Is this a new situation, or just a new to you RV
How is it on gas when not driving
Maybe it's an air circulation problem, not removing the heat while driving

It was always cold on ac. I've owned it for about 6 yrs, and it was always hit or miss on lap, over ''this past summer it doesn't work at all on lp, the flame stays lit , but melts down within hours of being unplugged. I have it out now, the chimney is fine, the baffle is good , no blockages or restrictions, have it all apart, cleaned chimney, burner orifice again, burner is clean, idk.

MY idea is still look at the troubleshooting guide in the service manual

So the big difference between running on electric and gas is circulation of the heat from the gas flame.
On electric the heating rod heats the tube through contact.
With gas the heat from the flame needs to rise through the chimney, you have stated it is clear, what about the roof vent is it clear?

I got it!, After pulling the fridge and cleaning the chimney and baffle I'm back in business. I want to thank most of you for all your suggestions. The chimney was not dirty, and no soot at all, just some light scale rust. The baffle was complete and intact with some very light scale rust. Cleaned it all up and put it back together, and now it's working great.

As an ugly side note, there is a poster on here who claims to know it alli. I was told by him, in a previous thread, YOUR CHIMNEY DOES NOT NEED TO BE CLEANED.. The same guy that accused me of lying about my water column pressure, cause apparently we're all to stupid to perform these simple tasks. We're all wrong sometimes.

I was once...back in '92!!
