Very interesting reading. I am manually changing the mode switch to AC when parked with shore power, & LP when moving. The Auto position does not appear to work. Bad board?
We rerouted our trip home from Duluth to Elkhart to have the Norcold absorption worked on. From watching the tech, it appears Phoenix did not install insulation above the fridge or install a baffle to direct the heat off the top to the exterior vent. We noticed a very slight increase in performance. On a setting of 9, we barely manage to keep 38°-40° in the lower compartment with outside air temps of 60°-75°.
The only time we use the inverter is power a small crock pot while driving. (Thanks for the tip Mrs Robbins, Earl's wife!)
