We carry all replacement parts currently available for the Whitfield Optima 3 pellet stoves. The Optima 3 was first made in 2002. The Whitfield Advantage Optima 3 (AO3) pellet stove is produced in both freestanding and insert models, which both take the same parts unless a part is marked as freestanding or insert only. Most parts are stocked, and any that are not stocked can be ordered in. Due to the large number of Whitfield parts available, not all of them have been added to our website yet. That doesn't mean we can't get them though! Most parts are still available direct from the factory. If you can not find the part you are looking for please call, e-mail or fill out our Parts Request Form and we will be happy to assist you. If you are not sure what parts your pellet stove needs, and would like help trouble shooting your stoves problem, please email or call us and we will be happy to help.
