1. The ONLY thing that I can think of that would turn the refer OFF and ON power wise is the safety thermal disc on the burner flue, but they do NOT auto reset themselves
2. The Refer will NOT freeze or have operational problems until the outside ambient drops BELOW 20 degrees, then will not cool well and once below 10 degrees will not cool at all. BUT NO DAMAGE to the cooling unit at all
3. Yes, using a 60 watt bulb will help cooling, but DO NOT use those Styrofoam panels to block the rear air circulation. YOU MUST HAVE REAR AIR CIRCULATION. As I stated, if the rear area overheats, you will "cook" the cooling unit and once that happens the CU is destroyed and useless.
4. Is this unit in a slide out and is the upper vent a side door or a roof top vent?
5. If you have blocked off the rear air circulation in the past, you may have partially destroyed the CU from optimum cooling performance.
6. Your model should also have the rear cooling fans and even in cold weather, those fans need to operate for optimal cooling performance, especially if the refer is in a slide room. Doug
