propane smell from furnace

I just had my winnebago at the rv service to get th propane system checked for leaks. I just bought it a month ago and have been fixing things so they fixed 2 leaks and i brought it home. they said the furnace worked but i never tried and probably will never. while i was working on the water heater spark box and the fridge spark box, neither worked, i noticed a propane smell by the fridge. the furnace is just below. the valve was off so i just assumed it was in my head. fixed the water heater and turned it on when i got home tonight . went over and started to put the covers back on the fridge and the furnace and noticed the smell is coming from the tubes that stick out of the cover for the furnace.. is that a residual smell or is it leaking?

Spray a soapy water solution on the propane fittings that go to the fridge and furnace with the propane on but not lit. It will bubble where you have a leak.

When the furnace is off, the only way propane can emit from the burner is if the gas valve is faulty.
Obtain an LP detector from a store(or if you have a extra), hold it around everything connected to LP, it is a hundred times more sensitive than the human nose to hydrocarbon gas. When it sounds, spray the area with your soapy solution/kids bubble-maker solution.
Occasionally, when the storage tank is nearly empty the settled odorant in the tank bottom is released in a stronger mixture than normal, and leave a strong smell after everything is turned off. Since the odorant is added at the distribution plant, it is possible for more than the required amount to be added to a tanker.
