For some reason my distribution fan isn't turning on after the stove fires up. I'll give you the full backround: Last year in april the stove stopped feeding pellets. I didn't look into it at the time, I just relied on my wood stove for the rest of the year. This past Friday I racked the stove out to fix the feed issue. Racked it back in and ran in test, problem fixed. Exhaust blower, Distribution blower, ingnitor operated as well as the auger fed pellets, problem solved. I then started the stove up but noticed I couldn't start the stove in Room temp, seemed like that entire side of the rheostat/switch was dead. The stove acted like it wanted to turn on when I went from OFF to Stove Temp but just a blip then nothing. I then turned the rheostat/switch to the Stove temp and everything was fine. The exhaust fan started, the auger fed, the ignitor started the fire, the distribution fan turned on as it should and the stove was running great. Then it started making the whoofing/helicopter sound with the flame flickering as so many of us harman owners get. I dealt with it last year so I felt like I should at least try and block a 1/3 of the air intake(no OAK) to maybe get rid of the noise. I shut the stove down to block air intake. So Saturday I racked the stove back out and put the tape on the bottom third of the air intake. Did a little extra cleaning and oiling while I was back there. I then racked the stove back in and noticed that the room temp thermostat had a disconnected lead at one of the connecters. Fixed it. Now I can start the stove in Room or Stove and everything works fine except the Distribution fan doesn't turn on after 5-20 minutes of running. I have a distribution power light but no turnie turnie. I did clean the ESP. Update: Just attempted to run the distribution blower on test and it's not turning. The light is on, I've got 1.5 amps to the distribution blower but it's making a buzzing sound and not turning or turning very slow. The distribution blower is not completely seized, it turns fairly well just not free spin like it should. Is this fixable or am I looking at replacing the distribution blower? Does this explain the rheostat/switch dead spot or would that have been the broken thermostat lead? Thanks for any advice in advance.
