Hey guys,
I have the Keystoker 70K BTU direct vent in the attached picture. I think my stoker motor is dead. My stove was out the other night. I confirmed the thermostat was calling for heat but the small fan on the bottom of the stoker motor wasn't spinning. I gave it a manual turn and it came to life. I restarted the stove and it died again in the morning. I don't know if this was caused or worsened by fines under the "coal pusher." I heard some noise coming from the stoker motor also in recent days.
The only marking on the motor is "280-9". I don't know if this is part #, serial #, or none of the above. I need to know where to get one of these babies as soon as possible.
Thanks in advance for your help,
Joe

You can take it apart carefully and clean it, it might come back to life, also, if you have a DV, make sure your Flume Switch didn't trip, sometimes it will trip off the stoker. Check the wiring, etc....sometimes the fines get into the windings. SOmetimes hard to find, except from a dealer.

I looked around to find a spare motor in case mine pooped out with little luck. I found the company who makes the motor, but I couldn't find the exact model listed. It might be a custom OEM motor for Keystoker.
However, based on the spare parts I've already bought from Keystoker, I doubt you'll do much better on price anywhere else. They are VERY fair in the price of spare parts. Just call them for a new motor and be done with it!
There's not much else you can do with these little motors - try to clean it, give it some 20w electric motor oil, and hope for the best. Usually, when they go, they're done.

take the motor apart and clean it......sometimes that works
I can't figure out how to get the motor off. I took out the two screws from underneath which hold the whole motor to the chassis. The whole motor including the plastic cam is now loose, but I can't pull it backwards and out. It runs into part of the metal stoker chassis. How do I disassemble this thing?
Thanks
Thanks
You need to empty the hopper. Mine has 2 screws. Take them out and pull the unit out. There my be some small pcs of coal on top and the sides jamming it. I use a flat blade screw drive and pryed the push block out little by little. Take your time. As far as the motor goes , my guess is the crappy spacer sleve and the 2 thrust washers are shot. Take the motor off the gear box and they have a real nice nylon spacer and 4 thrust washers at the top , why I have no idea. go figure. Grind the nylon spacer to fit the bottom part and use the 4 thrust washers. 2 at the top , 2 at the bottom. Take couple times putting the motor back on the make sure you have a littlle free play. Mine did the same thing. Would jam up , spin the plastic fan. Worked fine till the unit stopped the motor. Then had to spin it again. Found the bottom part of the armature was tore up and jamming the motor. Or just call Keystoker for a new motor and cam. It's only thier motor. Made just for them.
I got the motor off and stuck powered it up by itself last night. Motor seemed to work. I found that the stoker mechanism was indeed jammed with small pieces of coal along the sides. I pried it out and cleaned up the stove. Tonight after work I decided to re-light it. Before filling the hopper, I watched the stoker mechanism to see how it traveled. There was a lot of play from side to side in the stoker mechanism and when it withdrew, it cocked to one side inside of pulling straight back. I pulled the stoker back out and adjusted the 4 nylon screws until I had used up some of slop between the stoker pusher bar and the stoker chassis. I powered the stove back on and the pusher bar pulled straight back. So, I filled the hopper back up and fired it up. Once the load of the weight of the coal was on the motor, it failed again. The shaft going up from the motor would sometimes catch and sometimes spin freely. I think I need a new motor. Calling Keystoker in the morning unless anyone knows where else to get one.

jburke, how old is your Keystoker? I have one just like it and it has started to make some periodic squeaking noises that I think may be from coal jamming the pusher bar. Is that the kind of sound yours was making?

I think my Keystoker is approx. 10 years old. Yes, there is a squeaking sound. I noticed it last year but it was getting more pronounced. I think a combination of things added up to the motor finally giving. After re-installing last night and watching it try to push coal, I noticed that the squeaking sound coincides with the cooling fan moving up and down slightly. Looking closer, I noticed the reason for the fan moving up and down is that a nylon "bushing" (not sure what the right word is) around the shaft of the motor is rotating freely some of the time. In other words, the squeaking sound seems to be the motor trying to spin the shaft and sometimes not getting the grip it needs. I am ordering a motor or driving somewhere to buy one today. I will tear the old one apart once I get the stove going again and let you know what I learn.
