Atwood Helium fridge is no different then a Dometic/Norcold fridge except for the use of helium vs hydrogen gases.
Freezer section and food compartment section have separate evap coils for cooling
Freezer coil is first in process and has to get cold before food section coil can have capacity to absorb heat.
Freezer cold...food compartment NOT getting cool
Could be door gasket/seals leaking
Could be obstruction/blockage in food compartment coil/tubing
Could be dirty burner/flue/flue baffle if using LP
Could be faulty AC Element
Could be bad thermistor
Could be bad circuit board
Biggest issue.....
Atwood Helium Fridges (HE601/801) were first produced in late 2011 and GONE by 2016 (Dometic purchased the Atwood Fridge division in 2014??? and discontinued the HE Series in 2016)
Replacements parts...not available unless some vendor has something sitting on a back shelf (NOS --- new old stock)
Very little info available for the HE Series
Here is the only manual for them...not much info
