Norcold issue - Freezer Good, Frig Bad
The freezer is freezing thawed food solid but even on 9 the frig is closer to room temperature. Any help would be appreciated. (no food in frig)

residential might not be the best option for the OP TC, in his sig pix
its a matter of battery storage space
LP is very cost efficent
but we full time in a 1995 DP have had a residential compressor fridge for 7 years, and it works great, and we mainly dry camp/boondock
compressor fridge on electric, uses less power than RV fridge on electric
Pretty hard to shoehorn a residential fridge in a TC (the doors aren't that wide) Maybe in a Host Mammoth, maybe...
Certainly a compressor fridge uses less power than an ammonia unit on electric, way less, but on gas, the average ammonia fridge pulls about 2/10ths of an amp. Even with fans, the draw is below 2 amps or just about at the threshold amperage of a Danfoss unit, which is why, my next TC (if there is another) will have a Danfoss compressor fridge. Very efficient but very expensive.
A residential fridge compressor is similar in operation to a roof air conditioner, that is, the compressor runs full tilt until the pre set temperature is reached and then shuts down, waiting for the thermostat to call for cooling again and then it goes full tilt and the cycle repeats itself.
With a Danfoss compressor, the compressor throttles itself down (and draws minimal amperage) once the fridge is cold, why they are so desireable for RV use where power is always a consideration.
The Danfoss and the Dometic Waeco compressors are an offshoot of marine applications.
I believe that Dometic is starting to use the low amp draw Waeco compressors in their RV roof units as well.
