it's really easy actually. the blower is really just a motor and a fan. a fan cannot break. so the only thing that broke is the motor. go buy a motor (call around different stores for best pricing). then take out the old one and replace it with the new one. all you need for tools is a wrench. super easy. just make sure your electric power is shut off (from the circuit breaker panel) when you're working on it. $ S) `% w2 b! b) z# W9 B.

find out how many horse power the motor uses (i'm guessing 0.6HP) and the blower type (i'm guessing direct). you can find all those information on a sticker inside the furnace panel. * x+ j$ o# U, Z( Y A0 Y

the motor should cost about $50 to buy a new one. - @" t: T) n2 `( T- [) x3 T& U4 S* E7 H: p0 N
