How to remove blower motor for relacement
Turn off your power, remover both the upper and lower doors. You may have to disconnect some ''molex' plug connectors and you may have to remove some thermostat wires to gain access. If you remove any wires, WRITE them down as to what terminals they go back on. The molded plugs can only go on one way so don't be too concerned about their replacement UNLESS they are individual plastic plug ins for each wire. If so...WRITE down the location and proceed.
There should be either 5/16" or 1/4" headed screws securing the blower assembly in place. The assembly itself is probably slid into position on sheet metal rails or into slots. When the proper two (usually) screws are removed, it will merely slide out the front of the furnace.
Place it on the ground and look into the side of the assembly OPPOSITE of the motor. In there you will find a 5/16" square headed set screw. Remove that screw because it secures the blower wheel to the blower motor shaft. Clean rust, dirt and debris off the exposed shaft because that will inhibit the sliding of the shaft OUT of the wheels hub. Turn it over to the motor side up. There will be three bolts or scews securing the blower motor to the blower housing by means of a three legged 'spyder' mount. Remove them and work the motor and shaft OUT OF the blower wheel hub.
You are now home free... the motor is removed. Reinstall in basically reverse of the removal procedure. Hopefully you have an IDENTICAL replacement, so there will be no wiring adaptions to figure out.

If this is a split system, look on the side of the furnace, no luck? remove the front panel. look for a little plate or sticker label inside there somewhere. If you are in California, there is a Goodman (A.K.A.) Janitrol, in Ontario CA. They may be able to help. (sorry don't remember phone #)
