Having a strange issue with my gas range. Every so often (has probably happened ~3-5 times over a number of months) there will be a loud bank from the oven, at least once even strong enough to push open the door. This is usually during preheat, possibly when the flame was off, but not necessarily prior to the flame igniting the first time at all (unclear about that since we're usually not paying close attention to the flame in advance). Then for the next 5-10 minutes, the flames on the stovetop will be mostly orange, instead of the usual all blue. The first time it happened coincided with gas line work up the block, but based recent re-occurrence it seems like it's more likely an issue with the range (we have other gas appliances - dryer, hot water heater, grill - that appear to have no issues).
Any suggestions that might explain both parts of the issue?
