Hey, My 1 1/2 year old accentra insert stopped working yesterday. The compustion blower had started making noise about a week ago . I pulled the unit out and looked at it s almost seized. Is this common ? I thought these Harmans were durable. It's cleaned once a week ,although I only pulled it out for the seasonal cleaning once after last season. Are the bearings in the combustion blower a sealed unit or do they require some service also. It should be under warranty but i've come to depend on it .
thanks, bill
