Thanks Old-Biscuit for those precisions.
I do some more test yesterday and I leave the fridge running on LP for 2 hours at maximum settings (5) and the fridge almost froze up (ice on heat-sink and -15'C on thermometer). So I would say it work perfectly. But still no movement on the meter, needle is still in the far white zone...
I check carefully my burner and there's not******on it and flame is a nice beautiful blue with no waver.
This morning I remove the heat deflector sheet on the top grille of the fridge (outside) leaving me an unobstructed view on the fridge control panel wiring. The meter seem to be correctly connected, but the wires a thin like a hair!! Blue wire on the meter goes on the gas safety valve (I assume it's the safety valve) and the red wire seem to connect on the temperature controller but I had some difficulties to see were exactly... I'll check later with a flashlight maybe.
I called my Sportsmen dealer earlier today and the guy at the service department was completely confused about my gauge/meter problem... it's like if I'm talking to him in Chinese language!! Very comforting!!
