This listing is for a Viking oven bottom pan assembly. The oven bottom pan sits above the flames in the bottom section on specific models of Viking gas ovens. Their intended use is for stopping grease and other food byproducts from stoking the fire from the gas igniter. This model of Viking gas seems to have a few specific indicators that could signal a damaged bottom pan. There could be a possible gas smell coming from the oven and a sound of popping flames. This is because the pan is moving, allowing more gas fumes to exit the appliance. The flames popping are most likely from liquid spilling onto the igniter area. Always unplug the range from any electrical outlet and gas sources before beginning repairs. Wear gloves when working around the range area and look out for sharp edges.This is a genuine OEM part and is sourced individually from the original manufacturer. This part is compatible with Viking, KitchenAid, and Whirlpool appliances.
