Hello,
I have a Keystoker 90 and the combustion blower is acting up. I was wondering if anyone knows how long these blowers last before having to change them? Does anyone keep a spare one on hand? Some tell me that since it runs 24/7 that my electric bill will eat up any savings from using coal.
also is there any way to tell how many BTU's the stove is putting out?
thanks !!!!

What do you mean by acting up? Getting louder and kinda grinding noise?
Or shutting down? If the combustion plate (where the coal burns) gets clogged with ash, it will not perform optimally. You should clean under the burn plate really well at the year end maintenance of the stove.
Have you oiled the motor ? There are 2 small holes for the bearing, use some good small motor oil (3 in 1, etc).
I noticed ours is getting a bit louder, but works fine. (2nd season running) It runs 24/7 from Nov-Mar (Approx). Except for a few times shutting down to vacuum things out. May have to replace next year?
I believe it is a DAYTON blower,Model #7021-3466
#4C440 60CFM 3030RPM 115volts 60/50hz
old # 1C180
0.42 amps

My boiler's blower makes noise, sometimes it gets pretty loud and sometimes it gets quiteter. It's 35 years old too, so I guess it has a right to. A lot of them get loud because they are made of or mounted with rather thin metal and tend to develop a little vibration over time causing a harmonic sound in the metal. Also the bushings wear and the endplay can cause the sound. This in no way effects their longevity or performance. Try holding your hands on it while running in different places. If you hold it firmly with your hand does the noise stop and or change? If so, that is what you have. If it doesn't go away or sounds like a mechanical sound or grinding, start looking for a spare.
They should be lubed with no more than two drops of oil at each end at the start of and 1/2 way through the season.
Oh yeah, for you guys that worry about electricity costs... a good rule of thumb is $2 if your rates are low (maybe $0.05 per KWH) to $3 a day per horsepower on the motor. A 1/5 HP motor would cost around $0.40-0.60 per day. Ready to switch back to oil/gas?

By acting up I mean it was making noise, sometimes squealing! It also would come to a stop. I cannot find any small holes on this particular blower, it is a Dayton 4C761. I took it apart and oiled the end bushings and it has been working so far. Grainger has the blower for around $38.00 so I think I am going to buy one just in case...

That's what mine did, stopped. I'm amazed that they don't burn up when they do that. Mine quit about 3 years ago, I cleaned and oiled it up and it has been running fine since. The coal ash can't be good for it either.
