Otherwise I’ll have to have the dealer in.
Never ever give money to a Harman dealer - it's a matter of pride. Let's work this through. In/out vents clear or not? If you have money to fritter way try the Salvation Army or one of the many good manufacturers here. Then there is the Charles Manson memorial fund and finally throwing dollar bills into the ocean. All these options come before giving anything to Harman or it's dealers.
I can appreciate this in a way. My dealer is the only one on Long Island and they know it but they serve a purpose. Im a " if someone else can do, so can I" kind of guy.....unless we're talking about surgery
so trust me I dont want to have to call them in.
The combustion fan is clean. It is making a high pitch rotational type of noise from time to time, this is new. I question whether its thus not spinning at the right speed? Worn out?
Im going to double check the venting tonight.
Im fixated on the feeder assembly as I took the whole thing apart last season. I didnt realize it possibly controlled airflow in this unit. It looked like it bolted back in only one way. It seemed odd to me the limited travel of the pusher block though. Perhpas Ill post a picture of what I have back there tonight.
Thank guys for the support...
