What one needs to remember when = lighting the fridge is that once the air you pump into the firebox is burned (as evidenced = by a pop) there is no more air and the gas by itself will not burn down = there.  The only way air gets in is to go down the air shaft which comes out the = same place the burned gas exits (two tubes next to each other).  Fresh air is = pulled in by the draft that is created by the pilot burning.  Unless the = pilot light is burning burning, no air will be pulled in; the burner box is = completely sealed up.  The pop is caused by having too much gas and not enough = oxygen (air) in the burner box when you start clicking.
 
I have found that I can unscrew the = water drain cap inside the van, beneath the fridge, and then blow air in through the = drain hole using a plastic air pump; the kind that is used to inflate baloons and such.  This beats pumping and pumping and pumping the little built = in pump.
 
. Here is the procedure = -
1.  Turn on the gas.  Set the = knob to the light position, and hold in the button to purge air out of the gas line = and get the gas going into the burner.
2.  Let go of the = button.
3.  Pump air in through the drain = hole using the plastic pump to blow out the gas that entered when you were purging = the lines of air.
4.  Start clicking the clicker, = and keep clicking it rapidly as you press and hold in the button again.  = This results in more oxygen and less gas in the burner so the pilot lights.
5.  Keep holding in the button for = about a minute after the pilot lights.
Works for = me!
