Refrigerator not as cold on gas
I've been trying to troubleshoot my refrigerator for the past few
months. For some reason, when it is on A/C power, it cools just fine. When I'm on LP gas, the unit will not cool below 50 degrees! I've cleared rust from the burner, adjusted the flame height and seem to get plenty of heat to the evaporator coil. I've also tried installing some cooling fans on the condenser coils and inside the unit, but with little or no change. Does anyone have any idea as to why there is a disparity between using electric vs. gas? I would normally think that gas would be far superior, but that does not seem to be the case and I'm getting tired of warm beer. |

The only other thing that I can think of...remove the flame cover, use your hand and bang on the chimney to release any rust up in there, vacuum up the rust that falls down over the burner, try the gas again. I've done this on a few coaches and it helped. Warm beer is better than no beer.

SHane,
This is a strange symptom as propane is usually the best source of heat., but I would check the propane gas pressure and regulator. If you have the old single stage regulator , it may be better to change to the later two stage regulator. The Refrig mfg once had different size gas orfices for higher altitudes and different ambient tempertures. But I do not know if is still available, the size was stamped on the brass orfice casting.

Shane: I would bet that it has to do with the flame. The gas/air
mixture could be at fault or the flame is not hitting the designated target. R.e.

Well, thanks everyone!! I'm very grateful for the suggested remedies.
Here is an update- I removed the cowl around the burner and put a 90 degree bend in a piece of old fuel line and blew 150 psi air up into the stack while banging away on the sides. Probably 2 or 3 tablespoons of rust came out, not as much as I thought should. I also checked the flame and it is centered right under the hole in the bottom of the stack. There is a nice strong blue flame- and it certainly gets warm! I had installed two muffin fans on the condenser coils last summer to no avail, so I relocated them to the top of the compartment, just below the lid. There is a considerable amount of warm air now exhausting through the vent. The beer is still at 40 degrees, but we'll see where it goes overnight. --- In WanderlodgeForum@yahoogroups.com, "Stephen Birtles" > > Re-aim the flame > Stephen 77fc35 > > > --- In WanderlodgeForum@yahoogroups.com, "ronmarabito2002" > > > > > Shane: I would bet that it has to do with the flame.

Shane,
the link below is a good source for the repair. if you make it too hot you could damage the works. You may want to remove the fan mods and other add on's make the repair then reacess the mods. http://www.rvmobile.com/Tech/Trouble/gassys.htm GregoryO'Connor 94ptRomolandCa |
