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. 7 u6 w( D/ I7 E4 |$ L2 c& J: O* M

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. 7 N, ^7 Y0 ?2 X4 d( t. H; j2 C# n* R' a1 B
the motor should cost about $50 to buy a new one. 2 ~ M) K0 T6 h- f Y$ P# U1 ^( u) J
