I have a fairly newer sxs we moved to paint, cleaned cond coil. then it will only hold 44 in ref side, freezer will do -10 if set to it. I changed all parts def bd, thermo fan motor and fan blade, even heater, I noticed where air leaves top of freezer 1/2 seemed to be blowing randomly into freezer I also found small pieces of styro sooo I plugged it with a couple paper towels and now have air flow to ref side. Is that air channel supposed to leak air??? I have just installed fan and blade will ck again in 24-48 hrs No I chaged defrost bd too. Ideas here.
