I will respond to SEVERAL posts (Frank, Kim,  Shawn),
in this ONE email.  And I will refer to my photos at:

Frank:  I�m not as optimistic about this as you are.
If one looks at my photos one can see all of the CRUD
in the combustion chamber.  If one just blows air in
there, one may disturb the crud.  Now that disturbance
MAY cure the problem temporarily, but it MAY make
things worse as the crud may land in/on the burner
grill or the air hole or piezo lighter stem.  IMHO one
should clean out the chamber and the jet and clean off
the piezo lighter probe and the heat sensor.  This is
a DIY project.  If I can do it, anyone can do it.

Kim: Just be to sure, do you hold the �little button�
in for 10 seconds after the flame lights???  The heat
sensor (in the combustion chamber) needs a few seconds
to heat up to send the signal to the control unit
(Auto shut-off valve) to let it know that the flame in
on.  Also, if the flame lights  with the (by-pass)
button pushed in, why do you suspect the pressure
regulator?  Why not suspect the by-pass switch??

Shawn:  On my fridge, I can hear a definite CLICK,
CLICK, CLICK for the piezo lighter.  Also, just
�hearing� gas does not mean that the combustion grill,
or air holes, are not partially blocked  When I took
my combustion chamber apart, the heat sensor had some
crud on the end that MAY have interfered with the
sensing.  I would not jump to conclusions till after
the assembly is taken apart and cleaned.

I�m not sure about this, but�..  If, on your model,
the LED is tied into the heat sensor, that would
explain why it takes a few seconds to come on after
the propane lights.  Also FWIW if I turn the propane
switch AND the DC switch �on� at the same time, the
fuse melts.
