Im having troubles with my '88 VW Vanagon Dometic fridge. I thought I would check with the experts before I dive in. The fridge works fine with 110v and great with 12 v and even lights with 1st or 2nd try on the LP setting and stays lit. However, after being lit the fridge will not cool...nothing. I go check on the cooling after an hour or two and nothing. The Fridge is lit...the flue vent is warm, the LED light is one and the peep hole(in the lower left corner of fridge) is showing the blue flame. Any suggestions on what might be going on?  thanks, tyler
