see... NOW you know the difference
take a good look at Flame the fridge burner produces Now

the flame you have now is correct, and the one you thought 'looked' good before,
did not produce enough heat

cpachristopher,

I'm curious ... can you now hear the low roar of the burning refrigerator flame when standing outside the coach beside the refrigerator's air intake?

Hmmm ... after reading this thread, I'm scratching my head as to what a new gas regulator might have to do with the OP's problem? If the flame is the proper size and makes a loud enough burning sound ... then how can a new regulator do anything?

I suspect something else is wrong with the refrigerator that is causing electric heat to have an effect that flame heat doesn't have. Isn't a BTU a BTU?


DID YOU NOT READ MY POST? It explained why the LP pressure is critical and you cannot tell from the sound or size. Doug

Thanks to those who helped. I installed a new regulator ($40 and 5 mins of my time) and let it run all night on propane. The fridge is full of nice, cold bottles of water.

I am more than a little pissed that the "professional" RV repair guy I hired didn't even mention it or test the propane. I sure didn't know about it, but I'm just some office dweller!

Thanks again. Going camping this weekend with a cold fridge will be nice.


I take exception to you calling that Parts Changer a "professional". The problem with ALL walks of life is, there are people that claim to be Experts or Professional's and they only have a little knowledge, but enough to muddle thru. The sad part is YOU must pay them to come to you and then have no recourse when they do NOT have the expertise to fix items that DO TAKE Professional Knowledge. That is why most Mobile Techs require cash up front. The BAD ones want cash while real professionals usually will accept Credit Cards. Doug

When it kicks in, I can hear it. The cover is off the heat exchanger and I can feel a difference, too - meaning it is much warmer than it was before changing out the regulator.

I THINK it looks a little bigger. Hard to say for sure.

In any case, it sure works better.

it is the intensity and color of the flame
The fact that you can hear it, is an indication of the fuel air mix being correct,

Like you said, you can really see the difference with stove burners
