First time posting. I have had this Harmon P61a pellet stove for the past 9 - 10 years now. Works great. Until a few days ago, when I discovered that the Distribution Blower will only blow on high, even though it is set on low. After a while in will reduce to low, then back up again, mainly staying on high. I use the Room Temp. mode and a feed rate of 2, which has ALWAYS worked for me in this setting since I started to using the stove. Same pellets as well. I get 3 blinks on the Status light. So, after reading through past forums on this site, I did a through cleaning of the stove today. I found that the ESP probe was covered in ash and made sure that it was cleaned and now everything that can be cleaned and vacuumed had been done, including the two motors at the rear of the stove that had a collection of dust and crap on the fins etc. Stove pipe was cleaned as well. Over the past 10 years or so, I clean all the stove, 2 or more times a season, as I burn 195 bags (50lbs. each) per season. Has anyone had experience with this problem with the Distribution Blower? I read an old posting by a gentleman with this problem but I could not find anyone's reply to it. Thanks
