Make sure the flue vent pipe going up is not crimped or dented. Does the flue go up through the roof? Look carefully for bird/spider/insect nests inside the flue cap on the roof [ladder, flashlight, small tube-cleaning brush/etc.] With the fridge burning propane, that roof cap should get too hot to touch if the exhaust gases are flowing freely IMO.
The performance on electric and propane should be similar IMO.
How about the fresh-air ventilation screen on the exterior access door? Is enough fresh air getting in for proper combustion? Try propping that access door up, and see if that improves things on propane IMO.
