    The motor just hums, and it has a 10uf 260vac 2x330v capacitor. The cap has 5 terminals. The up/down rocker switch supplies 120vac to one or the other terminals that share a common neutral. One cap measures good, the other bad. I've had no success locating a replacement cap. Any ideas for sources for replacement caps, or substitution configurations?

    I havethe same problem...what kind of treadmill do you have....mine is a Healthrider 550i (one of many brands made by Icon.....Are there multiple caps in that assembly? I thought there are 2-10 mfd caps but I don't know the configuration either.

    I finally got around to digging a little deeper into the issue of the incline motor humming but not running. I had scrounged an 8uf cap from a junk fan motor, and thought I would connect it just to see what happened. In the process of removing the old cap, (unsoldering from the circuit board), and checking point to point for board integrity with a meter, I discovered a bad connection of one of the motor coils to its solder point on the board. After repairing that, I checked the old cap with my meter (using the Capacitance function). The cap was in fact OK. I reconnected it to the board, applied power, and the motor ran fine in both directions.

    Hello, HiFi Dave,
    The cap on my incline motor was mounted to a circuit board by 5 solder tabs. The markings on the cap made me think it was a double. It was not a double 10uf cap. The markings must have referred to the mounting configuration. It was just a single 10uf 330vac capacitor. The circuit board was physically mounted on the incline motor.
