Hi I'm Brian and I'm here to help! Can I please get the make and model number of the equipment in question?
Thanks for that model number. The damper motor is available separately, Click Here for the best price I found. The Lennox part number is ***** Before replacing the motor you should remove the motor and ensure the damper assembly moves freely without binding. Carbon and dust deposits can cause the damper to malfunction and not make the full travel therefore not engage the end switch. If the damper is opening fully but you're still getting a damper code, then the end switch is defective and that can be replaced as well.
