Refridgerator question

[PopUpMomma]

Why would a refridgrator run colder on propaine than on 110?  Some friends of ours can't cool when hooked to 110.  however, we seem to cool just fine with 110.  Any ideas?  They have a 1999 Niagra with a Domanic (sp?) fridge.

On our Jayco the propane cools more than 110v. I can adjust the cooling with propane, but not on 110. In hot weather propane cools better than 110v.Moose

On most PU refrigerators the 110 setting can not be adjusted by the user.  It is set at the factory and the unit turns itself off and on as needed.  With propane you can adjust the temperature and it is on, all of the time.  My unit works better on 110 than it does on propane.

There is a small advantage of using propane over 120 volt AC. Your average small fridge has a BTU capacity of 700 BTU on propane and 650 BTU on 120 volt AC.

If there is a big difference in the cooling or it doesn't cool on 120 volt most likely the 120 volt heater element has a problem.
Also make sure they are comparing apples to apples and not oranges. Our fridges do not have a thermostat so the inside temp varies with the outside temp.
Most fridges will cool great on either when the outside temp is 70 degrees and not work as well with temps in the 90's.
We've had a friend complain that on propane it wouldn't cool but on 120 volt it worked fine. After some questioning when I couldn't find a problem it seems they were dry camping in 100+ degrees in the desert on propane and at 70 degrees in their driveway on 120 volt.
