Topic: Refrigerator Temp Posted: 03 Aug 2014 at 9:44am |
The other day when it was in the 90+ deg. range outside the Refrigerator Temp. could only get down to 48 50 deg., but over night the temp when the outside temp fell it went back to 34 deg. I read in one of the treads on this form that a absorption type frig can only go 40deg below ambient(outside temp). if this is true it would explain the temp swing.

Were you plugged in or running on battery or using propane?

I have had that happen when using battery while travelling down south. But never while plugged into power. I know it takes a while for the fridge to cool down when first plugged in.

What you're seeing is normal per my experience. Overall about 40F delta from outside ambient. There is a lag as it warms up outside and a longer lag as the fridge tries to cool down after a hot afternoon. Propane or shore power about the same, 12V battery not so good. Opening the door is really bad.

I believe that the 40F differential applies to thermo-electric coolers, not gas absorption. |

My post was not based on theoretical thermoelectric or absorption technology. It was based on my observation of the Dometic 8501 in my RP172. It reflects not only the technology, but the particular application including unit capacity and box insulation. I wish I could have maintained 40F (4C) with ambient at 95F, but I couldn't. In testing I did use a wireless thermometer to avoid unnecessary door opening, but the fridge was in use. The larger Dometic in my Camplite works better but I attribute that to better design and construction.

My 8501 so far is doing well, no problem maintaining in the 30's in 95+ heat. This is on propane, or AC, never tried it on 12V.
I did add a thermostat and 2 12V muffin fans to move air through the compartment, I've done that on many RVs in the past with good results. These were added to the rpod within days of bringing it home |

The thermostat and fans sound like a good idea. Can you show some pictures or explain a bit more. I'm not sure why you would need another thermostat?
I haven't had any probs with the fridge, other than a quick defrost after a couple of weeks on the road. I'm guessing moving air through the box would help. Pictures would be great. thanks, fred |

The specs I found said it will maintain at least 44 degrees up to 90 degrees ambient, but I've seen better than that with mine.
That said, I've posted here how in the last year I've had issues with the gas mode on our fridge. The latest diagnosis is it may be the gas valve which will be very expensive to replace. I'll be messing around with it for a while before I go that route.
