My Harmon P68 appears to have had a nervous breakdown

[Chris Kaufman]

My P68 has issues. It has been a dynamo for the four (five?) years that we have had it, but recently it started to fall apart.

A couple of months ago, the blower motor (the one that blows heat from the stove to the room) stopped working. Then the igniter went. We had been using manual ignition and enjoying the warmth of just stove heat up until a couple of days ago when power seemed to give out to the entire stove. We still get lights on the operating panel, and when we put it on TEST there is a faint humming noise, but no augur motion or internal fan activity.

I would have thought the one 6AMP fuse listed on the unit might have blown, but then we ought not be getting any power to the unit at all, right? Any ideas out there?

Hmmm, was the convection blower replaced? If not and the stove was burning like a dynamo without it, you may have overheated something as I believe the convection blower allows for cooling.

No exaust fan= no vacuum and no other stove functions. Will have to clean and check it. Thats where I would start.

Yes, but it is the "faint humming noise" that has me thinking. Unless of course the exhaust fan is just plain plugged up good and not turning: but trying to

Was my thought. I worked on a countryside yesterday with a stuck exaust fan.

circle gets a square...my guess as well.

Take two aspirins, step away from the stove for awhile, catch your breath and clean your stove and vent system. Replace that distribution blower if it isn't just plugged with dust bunnies and spare pets.

X gets the circle and square.

Just to be clear, don't think the faint humming noise is a fan. combustion blower was the one that was working, distribution fan was not. and WOW - thanks for all of these quick responses. have been taking breaths and dutifully cleaning.

Don't rule out the board, if you lost power during one of these recent storms (where are you anyhow?) and do not have unit plugged into a surge suppressor or used a generator you could have compromised the board.
Clean first

Did we knock a wire loose while fiddling with the dead fan???

Had an episode last year when the blower fan sounded off for an hour or so (running slower). In talking with the neighbor computer geek who has monitors to protect his equipment, lower power fluctuation from Ontario Hydro. Wouldn't have figured it out otherwise...
