This upgraded double paddle blade fits many Harman models. 5" diameter. These new blades have rivets in each petal to prevent any separations.
Old blades may be welded on from the heat, if so the blower shaft can be cut from the back of the stove with a sawzall using a long metal blade. Then a new blower and blade can be installed. Needs a T-20 Torx bit to properly tighten the double paddle fan blade on the motor shaft. They can be purchased at your local hardware store.
