Replacement Harman Fan Blade 5 Inch Double Paddle 3-20-502221
The Harman Combustion/Exhaust blowers require an impeller to aid in keeping air blowing thru the pellets to keep them blazing and to exhaust the smoke out of the stove thru the venting. The impeller can become damaged thru annual cleaning or if they become seized onto the post of the blower and cannot be removed when replacing that part. If the impeller has become warped or otherwise damaged it should be replaced.
