Hi everyone, I've searched the forum and found a couple of loosely related but nothing definitive. Hope you have some experience to share! With this 2016 cold snap my Harman PF100 (since 2005) isn't working and I need some help.
Whats Happening: It will try and cycle through a burn process and won't ignite the burn. If I do a manual burn it will establish for a short while (3hr), not quite get up to temp and a good many pellets are "charred" but not fully burned. The air distribution blower (supply to air ducts) will cycle intermittently, but not sustained - as if the burn is not up to temp.
What I've done so far:
- I had the burn-pot bubble problem and fixed this with a patch of perforated stainless steel, as well as a new igniter. Seems to get scalding hot.
- I've had the dealer thoroughly cleaned all the outbound exhaust pipes, ESP probe (looked good), as well as the combustion fan.
What i've noticed. Seems like the combustion fan motor is making a squealing sound as if the bearings starting to fail.
So with this cold I need to keep my family warm, and while my hearthstone wood stove belts out the heat - just not enough
.
Does anyone have any idea on potential sources for incomplete pellet burn? The dealer I bought from is no longer with Harman and I don't want to burn through money try to trouble-shoot this.
