Keystoker Coal Stove - Fire Burns out Gear Motor

[Kola]

I awoke to discover my Keystoker coal stove had gone out overnight. The
fire had moved up the chute and burnt out the gear motor - putting itself out.
The pistol motor was still running when I got up. The motor was replaced and
all seemed well only the fire continues to move up the grate threatening the
gear motor again. I am cold and frustrated. The stove has
been thoroughly cleaned (unless I have missed something I don't know about) -
including the chimney pipes, under the grate etc. etc. The chimney itself, appears clean and shows
clear when I hold a mirror up to it. I love this stove - it has totally heated my
home for 16 years and, during my partner's lifetime, was beautifully maintained.
I am trying to keep up the tradition. I would be very grateful if someone would
share some knowledge about this problem. Thanks so much!

I think this Forum is for wood stoves...there's another for coal.

I don't know squat about this stove, but Corie might. You could also try the coal burner's forum at www.nepacrossroads.com.

Just curious, has anything changed. Is there a gasket on the coal feed door that needs replacing? Did you change coal nugget size?

I've found the fire in a coal stoker stove will travel towards the air. Is this an Keystoker with the carpet slide feed mechanism? If there is air leakage anywhere around the feed system, between the hopper and the feed funnel, etc. the fire will try to travel back up the slide and into the hopper. Get some gaskets, furnace cement and a flashlight and do some investigating.

Thanks Corie, that was my thought, fire needs air.
