We just bought a house with a Harman P 61-2. Wouldn’t start so we replaced the combustion blower and distribution motor. Our issue is when we opened up the back of the stove it had a different combustion blower than what was on the manual. It had a 3-21-00945 installed but the manual calls for a 3-21-22647. I confirmed with a local pellet stove place and they said to stick with the one in the manual and not the one that’s already in the stove. Now it’s making an awful noise but not sure if that’s normal since we’ve never heard a pellet stove run before! Thanks!
