Norcold cooling problem

[Thumper13]

I have a 2019 Norcold NA8LX that after 12-24 hours cools great on gas, freezer and refrigerator. On electric power, after
24 hours the freezer works great but the
refrigerator will only get down to about 65F. Whats's going on?

So Why does the freezer work perfectly on electric power?

There are more btu's from the propane than from the 120 volt heater.

The heater may not be "seated" correctly.

Check to see how many watts it is drawing--it ought to be around about 325 watt.

It is also possible that the 120 voltage is on the low side. Power varies by the square of the voltage so:

120 x 120 = 14400

and

110 x 110 = 12100

That's 16% less power, so only 273 watts.
