Refigarator star up with gas.
After coming out of winterization my Dometic refrigerator would not start on gas. It worked fine on electricity. I could not see the burner ignite. So, I tried the stove burners. No luck. When I tried lighting the stove using a match, the 3 burners all lit. I the tried the refrigerator again and low and behold the line had purged itself and immediately lit. So, after turning everything off in Winter, the gas line needs purging. Try liting the stove burners first and then turn the gas on.
