Actually two questions...
We got flooded out of our house by Imelda, and will be living in our 5th wheel for the foreseeable future.
We have a brand new Dometic fridge that is running almost cool enough on max setting. I know moving the slide up or down the fins changes the temp, but I can't remember which way is which.
question 2 - I know it cools faster on propane, but should it maintain the temp I want on AC? Outside temps 80s to low 90s.

You talking about your refrigerator or the a/c : air conditioner? I have yet to hear of running the a/c on propane. I understand that if you put a sun blocking shield over the side of the RV where the fridge vents that will help. Reflextrix should work well and you can get that at Lowes or Home Depot. Some people install a fan inside the fridge and/or behind it.
For the a/c pull the cover off and clean the coils. Clean the filter inside.

Generally most people think that the fridge cools down faster on electricity.

Down = colder. Yes, should maintain on electric. Electric should take it down and hold it too.

Although we no longer have a gas-electric refer, on all my 3 past TT's, electric always brought the freezer to -2 and the refer to about 36-38 when outside temps were in the 80's and 90's. I moved the temperature slide all the way to be bottom, as far as it would reach and just left it there. Never had a problem, and any time of year, under any conditions, the freezer was always -2.

hmmm.....we were always told that sliding it up meant colder. Inquiring minds sure would like to know. Would it matter what kind of rv refrigerator it is?

OK, you are correct. I looked up a couple YouTube videos and "UP" is colder. Sorry, my bad.

I guess I had the wire stretched to the max with the slide going up.

A new fridge should have the proper fin setting printed on the wall next to it.

Up is colder, down warmer

Get a snip the tip, and then you don’t have to worry about moving it

My experience is Dometic fridges do better at 7-8, instead of max.

Try going down a bump with the outside setting, wait 24 hours, then readjust as needed with the thermostat inside

Yes, it should maintain temp on electric.

Moving the thermistor can affect the overall fridge temps by 4*F-6*F on the Models that have 'AUTO TEMP CONTROLS' (NO temp adjustment settings)
UP on the Fin....COLDER
DOWN on the Fin..WARMER

[image]

Models WITH Temp Setting controls (1-5 & 1-9) should have the thermistor left in the OEM position (mid FIN on fin specified by RV MFG.----far right/far left/10th fin etc)
Fridge Thermostat is factory calibrated to control temp based on feed back from thermistor on specific position on fin


Propane will START the cooling process quicker then Electric due to the initial heat transfer by the hot flame
Electric and propane are sized to produce roughly the SAME heat required to boil the ammonia into a sufficient quanity of vapor for the cooling process


Is it time for your medication or mine?
