How to convert a gas range to operate on LP gas

This DIY repair guide gives step-by-step instructions on how to convert a natural gas range to operate on liquid propane (LP) gas. Gas ranges typically come equipped to operate on natural gas. Install the LP conversion kit if you want to use LP gas. This guide is for reference only; carefully follow the instructions included with the manufacturer-approved LP kit to convert your range.

This guide shows how to convert some Kenmore, Frigidaire and Electrolux ranges to operate on LP gas.
