A:Answer Hello - Thanks for your question; we are happy to help! In the event of a power failure, the surface burners may be lit with a match. Using extreme caution, hold a lit match near the ports beneath the surface burner cap, then slowly turn the knob to the LITE position. Once lit, surface burners will continue to operate normally. In the event of a power failure, the ovens are inoperable and no attempt should be made to operate them. Thanks for checking. Olga@GEA
