Harman Stove Making Noise/Squealing during feed cycle-
Scott Writes In:
We have a Harman P38 pellet stove installed in 2007 – it’s been working great … until last night. I started it up and when the auger kicks in, it has high pitch squeal. Is there anything we can do to stop the noise, or will we have to have a technician come out?
Mr. Pellethead Replies:
Thanks for contacting us. In most cases with this type of noise on a P38 or any Harman Pellet or Corn model it would be one of the following-
If you would rather schedule a tech to come out then to troubleshoot yourself just let me know and I will get you to the right staffing to get that set-up. Otherwise we’re happy to help troubleshoot and I’m confident we can figure out where the issue is coming from and what we need to do to resolve it.

I have a Harman pc-45 stove. I just recently changed the blower motor (squealing). When I hooked it back up, it would appear that the blower motor wouldn’t shut off(low/high) and it would engage the auger motor. The problem then is the igniter wouldn’t come on. I changed the circuit board(bought from yins), but still the same problem.
Any help would be greatly appreciated

Check your feed rate the stove may not be burning hot enough to prevent buildup around the pellet entry/ end of auger. After professional cleaning I burned 3 or 4 bags and a high pitched squeal begin every time the auger ran. I assumed it was a pellet lodged and ran for 20 minutes hoping it would dislodge. Clearly not the problem. After some searching on threads everyone was pointing at build up. I pump the stove up to max to burn everything clean similar to your oven it should get hot enough to burn anything off. After 20 minutes of my stove running as hot as it could the squealing ceased. When I was turning everything up to attempt this i realized the gentleman that cleaned the stove had the feed set at 2. I suggest running at at least 3 to keep your stove hot enough to prevent buildup. In case your not looking to do that ramp your stove up to wide open once every week or 2 to clean things up. Otherwise u can get in there with a fine wore brush and screwdriver once a month. Your choice. Happy burning hope this helps some people out.

After many attempts to stop the seemingly random squeal I felt hopeless. The sound was causing terrible stress to our house…then I got a tidbit of advice and took it a step further. Here my fiends is how you stop the squeal:
Go buy some dry graphite powder. Run your stove out of pellets. Grab a pint glass or 2 full of pellets and put them in a plastic bag. Add about 2-3 grams of the powder and mix it up until the the pellets are grey. Turn your stove on and dump the graphite coated pellets in the empty hopper. My squeal went away INSTANTLY and has not come back for months. I only used about half the graphite coated pellets. Hope this helps

Idk if you guys are experiencing the squealing even after cleaning or not. I was under the impression I had a pellet caught in the auger but I’ve done some reading on other threads. I have noticed a lot have said it’s carbon or creosote build up at the end of the auger/ pellet entry to burn pot. I tried to clean things out well with my scraper and a screwdriver but the squealing persisted even after rigorous cleaning. I had only went through 3 bags since professional cleaning. When cleaner started stove he had set feed to about 2.5. Assumed the lower feed left the burn temp a little lower allowing build up. If u can handle the heat crank your pellet stove wide open for roughly half an hour. Should get hot enough to burn everything off. I tried this as last ditch effort to avoid taking my stove apart. 15-20 minutes and mine is squeak free. Hope this helps anyonr having squeaking migraines. Happy burning!
I tried the graphite coated pellets in the on my P16 Harman. My squeal went away instantly. Thank you Bill
I read a lot of blogs & videos about how often people clean there stoves. I am shocked at what i see & read 1 to 2 times a year! I have had trouble free and very efficient hot burning stove since my purchase from oct 2014 . I clean my stove during winter every 7 days thoroughly way beyond what is recommended in the manual because i find it a eaiser & faster clean this way because of less build up and trouble free operation with no excessive wear on components.
Thanks for the comment. You are 100% right. The more often it’s cleaned the less time it takes, the more efficient it runs, and the less probability of issues arising. 95% of all of our service and maintenance calls are related to cleaning issues. It’s great to have a set schedule in place like you do – everyone should take note of this. We appreciate your contribution and if there is anything we can do for you please let us know.
My squeal seems to come when the distribution comes on and stops when it turns off. I was able to minimize the squeal by running it on low. I’ve placed the feed rate on 4 that helped a little. I’ve seen internet places suggesting putting 3 and 1 oil into the (so called) oil ports. It is a P61A. Suggestions?
Thanks for contacting us, happy to assist. If you have narrowed it down to be coming from the distribution fan, then the noise is more than likely associated with the motor there itself. The original motor is a sealed bearing fan – there are no ports to accept oil into the motor. We do now offer a replacement motor where you utilize the existing fan housing and squirrel cage. Here is a link to that. Any other questions please let us know. Thanks, Taylor-ESESstoves
Thanks for the quick turnaround. It is the motor, I’ve been a technicians my adult life and I have heard many bearing issues and this was my first thought of the noise.
