If your gas oven is not lighting, takes too long to ignite, or you smell gas before ignition, the safety valve may be failing. The EvertechPRO replacement for Frigidaire 5303210798 gas oven safety valve is designed to restore proper gas control on select Frigidaire, Kenmore, Tappan, and Electrolux gas ranges and wall ovens. This valve works together with the igniter to ensure that no gas is released until the igniter is hot enough to burn it safely, improving ignition reliability and reducing the risk of unburned gas in the oven cavity.
