Video starts at high volume and goes down to a low then right at the end volume goes up again. Will try oiling the exhaust fan today and see if that helps.Listened to it multiple times, can't make it out. You have two fans, room blower and an exhaust combustion blower....
Thanks for the tip.Easiest way to see which motor is noisy on a Harman is to first put it in normal start up and listen. That starts comb blower and not dist blower. If quiet then put in test mode. That starts dist blower. If auger motor is suspect, put in normal start up mode once it starts to feed, open the door that shuts auger off. close the door that starts auger back up.
