RV Repair: Fridge Lp problem and AC leak, steady drip, lp problem

Question
Two questions:  I have a 1997 Norcold Model 443 refrigerator that works well on AC but won't seem to light on LP this year.  The book says to try to light for 30 seconds and if it doesn't light, to turn off, wait 5 min and try again.  Should I try longer for the intial lighting of the season?

My dometic AC unit has started leaking inside.  The outside drain tube is clear and some water is leaking off the roof outside, but I am also getting a fairly steady drip inside.  I did take the unit up this winter when I repaired the roof and replaced the rubber roof.  I did install a new roof gasket when I reinstalled the AC unit.

Answer
while the refrigerator is trying to light, tap on the gas valve, if it is stuck this may be the problem and allow gas to flow through.  Also, if the unit has been sitting for a while, retry the procedure several times.

As far as the leak, you may have a warped/ damaged drain pan within the a/c unit or the upper unit may need to be tightened.
