Okay. Combustion blower is acting spuratic. Random bursts of power then it slows way down. How can I adjust this on the circuit board?

Recent Harman Combustion Blower Upgrade! but why?
Hello After working on a few Harmans, I found the new Harman Combustion blower is now 1.75 Amps and the older blowers are only 1.50 Amps. Harman does change the part # on upgrades and sure enough, the new blower does have a new part number! If anyone has any insight as to why this upgrade was...

in in the process of installing a p68 and before connecting to the vent i thought i wiuld run a few tests on it. I have a draft meter set up and also a harman diognostic to see what the stove is doing. So with the stove in test mode all motors run. However,i noticed something odd with the...

Definitely - and I agree for sure but this time it’s very drastic. Sorry if I’m talking around in circles. I won’t have a fix until tomorrow and that’s okay! My guess is because I ran it on generator that I fried the board and that it is just not responding well. Thanks guys 
What generator were you running it on, maybe make/model ?Definitely - and I agree for sure but this time it’s very drastic. Sorry if I’m talking around in circles.

Okay guys. It was the circuit board!! My amazing dealer came out and replaced it. Our guess is due to the long run of extension cord I was using on my generator it messed the circuit board up and everything was getting low voltage. Glad to have this behind me -

Ty! After spending so much time on the back of the stove I noticed my p68 doesn’t have any leg levelers installed on the back which could certainly be making it louder because it’s steel that sits on tile! Do Harmans have leg levelers or do you have any idea on something soft and non combustible that I could place between the stove and the tile?
Use 12 gauge or lower number for extension cord, depending on length.. Lower number equals the bigger wire for current loads..
Never seen leg levelers. I have mine sitting on a tile pad..
Sitting on tile will not make it loud. It is heavy steel. They all sit on tile, concrete or stone. The tin on these stoves are well secured and typically does not rattle . You must run these on an inverter generator or the board can get damaged. It only pulls max of about 410 watts which is only about 3.5 amps. I would say the generator was the culprit as opposed to the cord.
7-8 years ago I remember emptying a bag into the hopper and seeing something metal sticking out of the pellets as the bag finished emptying. Turned out to be a big bolt. Must have fallen off some machinery at the plant. believe it was Fireside Ultras I was burning at the time, used to be in most Home Depots in southern NH at that time. Those were actually very good pellets at that time.
