i installed an amish cooling unit in 2014. last july, it went to no co.
i did all the resets on the circuit board, and the recall boxes.
still had no co. the norcold board had several very dark spots on it from overheating so, i replaced the circuit board with a dinosaur board, it worked, but it still didnt cool enough on lp.
i talked to the guys at pine refrigeration, and they recommended replacing the orifice and burner. they said it had enough corrosion inside the tube to cause the gas to not flow properly.
that worked. i now have 36 degrees with a 4 thermostat setting in the fresh food part of my frig. temp outside was in the 80's.
also for hot weather, make sure the fans are in working order. i now have two fans that are thermostatically controlled. when i pulled the refrig the first time, one of the fans was mounted upside down,
doug is right, clean burner and orifice are critical.and you cant adjust the burner. it only fits one way.
