pilot not lighting on NG Coleman mobile home


Bought old trailer. Furnace is natural gas Coleman 7656B, series 856. Got new thermostat, wired correctly (talked to honeywell). Bought new thermocouple, tried adjusting several times. MY PILOT WILL NOT LIGHT! Holding the PILOT position and providing a match I get a blue flame that comes out fan-like, will not seem to affect the thermocouple and dies when I release the button. Any help would be appreciated. much thanks to all.

The usual problem is that the pilot burner orifice is dirty and needs to be cleaned. That involves removing the brass ferrule that holds the pilot tubing in the pilot burner with a 7/16" wrench, which allows the pilot orifice to be removed. Some pilot orifices can be cleaned with a wire from a wire brush, others may need to be blown out with some compressed air or replaced if the holes are too small and can't be cleaned properly.

Am going to try to clean pilot orifice right now. My unit is small and tight and I don't have much room at all. That's why this whole ordeal has taken way too long and been painful. Will update later. thanks again friends

And if that does not work you replace the whole pilot burner as those orifices are very difficult to clean or get out.
