I have had, in the past, similar prolems. But on recent trip where temps ranged the mid 30's during day and 2 C at night (yes, cold but very dry mornings) and up to 5,000 ft alt. the fridge worked like a champ, staying lit and working very well in those conditions.
I can't explain why it is working so well now.. I had cleaned every part of the system a few times over the years, the last time was last summer.
