Teal how old is your trailer/fridge?
As Charles suggests cleaning the jet can help.
As a side note if my fridge
has not been run on propane
for some time - i.e. its been in storage for the winter - it can be hard to start the first time.
I always make sure the propane tank is fully open. I light
the stove in the trailer first to fill propane into the lines. When starting the fridge
I need to hold the knob in pilot/lighting position for a fairly long time after clicking the starter and getting a flame - sometimes as long as 30 to 40 seconds before the flame will stay on. Mine is an older fridge
though which may or may not make a difference.
The little flame is hard to see sometimes particularly in bright light
so it may be lighting
but you just can not see it. It helps if you can block the sun from the little window to actually see that there is a flame. If you have someone with you that can stand behind you to block the sun that helps. I actually keep a small bit of aluminum sheeting I leave in the outside fridge compartment to create a sun shield to help me see the flame in bright light
. Putting your hand on the stack to feel if its warming up is one way to tell it is light for sure as well.
