I'm thinkin the refer is good. Was worried about a damaged cooling unit.
At 8 this AM I moved the selector from MAX to 7 .. the temp has stayed at 26 or below with inside RV temps as high as 101. RV parked in full sun with back of fridge to the sun.
Been measuring the the temp of the tube above the evaporator. Some advertisement for a product to protect from overheating says fans on this tube should start at 139 degrees and shut off at 109. Mine has done on its own without fans but I can lower the temp with a small fan.
I've tried all kinds of fans, locations and baffles... nothing seemed to help the
This tube never got very hot on gas. Gonna let the thing run until this evening and switch it back to LP with no other changes and let it run for 24 hrs. Maybe now that it is hot the LP mode can keep it hot.
Earlier while messing with all this the refer was empty. Sometime yesterday I put 2 gallons of water (room temp)in. That was there through the night and was not frozen this AM even though the box temp was 23. Around 8 this AM i opened the box and added 2 frozen blue packs and 5 small palm sized cold packs. The temp went to 25 but was back down to 23 shortly. . have maintained temps within 3 degrees while interior RV temps have increased almost 30 degrees.
Been interesting --- will report tomorrow.
