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. ; l* r8 T( o7 ?- Q$ w

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. # p. R: G4 b" R% S5 I# b+ n# ]3 o4 E( k6 Y4 x# A2 q+ R2 p
the motor should cost about $50 to buy a new one. R' a; [7 f0 i4 U- q$ p4 c/ F P- K
