Had the residential fridge service folks out and they found an issue with the freezer - the drip pan that catches the water from defrosting was full of ice and had run over the catch pan into bottom of freezer such that it too was full of ice. Tech said this is fairly common with these side-by-side fridges and the "fix" was to install a "transfer heater" in the drain line - sounds pretty sophisticated but the heater is actually a copper wire that they run from the heat/defrost coil down into the drain line. So, when the heater turns on to defrost, heat is transmitted via the copper wire down into the drain line. It's been 2 weeks roughly since the fix (clean out all the ice and install the transfer heater) and there is no ice build up in the freezer and the fridge portion seems to be keeping better overall temp (tech said too much ice in freezer can overcool the air going into fridge compartment) - maybe that was what was causing stuff to freeze up in fridge.
Will let you know how next trip goes in a week or so.
