My daughter and son-in-law just took possession of a repo home that has a Goodman GMT090-3 furnace. We tried to get it fired up, but the blower doesn't work. I'm leary about just changing out the circuit board, but can't seem to measure any power across the motor. I also have continuity across the start capacitor. It is not the capacitor, but the wiring. Is this normal? The wiring diagram doesn't really help much so I don't know where to check the power across which leads. Any ideas would be much appreciated. We also don't have a manual at all so I have to wait until Goodman can send me something. Thanks.
