Most gas ranges are designed with very similar set ups. The information below will help you understand how most gas ranges and ovens work. Before looking at the problems with gas ranges, it is important that you have an understanding of how they work. If you have a gas wall oven, ignore the parts about the cooktop. If you have a separate gas cooktop, ignore the parts about the oven. A range is just a cooktop on top of an oven that shares a gas and power supply.
Gas ranges basically take natural gas or propane and turn it into concentrated heat that you can use for cooking and baking. There are burners on the cooktop and one or two burners in the oven which burn gas that has been ignited by a pilot, spark ignitor, or glow ignitor.
