I have a similar problem if I have not used the gas for a while. Even when the stove lights, sometimes the fridge will not. Have learned that I must turn the fridge OFF for a few seconds, then restart using manual LP mode, not the AU automatic. Sometimes this takes a couple of times, but it always starts. Then I switch it back to AU mode, and all is well.
