Well thanks guys. the thermo sensor is working and the fan too.

Touching the 2 wires that connect to the thermo sensor was not so good,
after a few sparks (I know, logically it should work)!!! I tried a
different approach, heat gun on the sensor. The fan started right away. The
fan sound like a 35-year-old lawnmower but she blow air like hell.

Well it's to cold up here!!!

The fridge went too -5C (23F) on propane after 4 hours at 65F outside. I
think its good enough (my beer was cold).

I wonder how many hours I can get on 1 propane tank!!!
