RE: When I try to light it, the little red display at upper
right glows briefly, then goes out.
BTDT with my '90.  Usually happens after the gas has been turned off at the
tank for some time.  When this has happened in the past it has always lit
when tried again in a few minutes, one occasion tried again after a few
hours and it lit.  The only conclusion I was able to come to was that the
system was sensing 'no gas' until enough gas worked into the system.  I know
that doesn't make sense, I don't think the fridge can sense whether or not
there is gas present or not.
