Ok Doug my refrigerator is a Dometic RML 8555 absorption unit and it's less than a year old. My one friend has an identical unit about the same vintage and the same brand of motorhome and the same problem. Another friend has the same brand of rv and it's also essentially new but the fridge is a smaller model Dometic and I don't know the model number but he has the exact same problem. These friends of mine have had their gas regulator,gas solenoid valve and board changed, burner cleaned etc under the watchful eye of Dometic who covered some or most of it under warranty. Bottom line, Dometic says that's the way the fridges perform and don't expect much more than something like 43 deg in the fridge at about 85 ambient. In addition, these fridges have underperformed like this when they were brand new and it's taken months of harping to Dometic to get nowhere. I haven't checked the gas pressure yet but will do that next. Since I have a newish Marshall gas regulator, should I adjust it to increase the pressure if necessary? To be clear, the freezer works fine on ac and propane but the refridge works fine on ac and barely on propane.
A LOT of my B+ motorhomes have the 8555. NEVER have had a complaint of poor lower section cooling that could NOT be fixed. Very rare to even have that complaint on the 8555. INSTALLATION parameters are HUGE in the correct operation of any RV refer. The rear cooling air must be routed up and out correctly and it is a must that the cooling air is routed THRU the fins of the condenser. Any gap between the edge of those fins and the outer wall will allow cooling air to flow away and not thru the fins. Also, Are any of you or your friends refer installed in a slide room? THAT is also a different situation that usually calls for a separate exhaust fan blowing out the top door. Doug
