    It's a horrible design, as soon as the econo gets some dust in it the gears bind against the sheet metal and the actuator dies or the gear hubs strip out. I have made the repair by replacing the gears which, while not a fun job is possible and cheaper than a new econo. Carrier never seems to have a handle on MicroMetl products. Maybe because micrometl changes their design as often as Carrier does. Moving forward, silicone at the inspection keeps the gears from binding.

    Finally. I have a good answer. Good and cheap. I had the same thing happen to me. The white plastic gear splits at the square hub in the middle. I placed a gear clamp (hose clamp) on the hub. It pulls the cracked part back together thereby keeping it from spreading apart again.

    sorry i didn't get back sooner, easiest way with this repair is to drill out old gear install new shaft and clamp for blade. worked out slick:

    Experienced the same problem, for a quick fix I swapped the one with the cracked hub with another since the teeth were fine and only the square drive hub was cracked, I figure I have 9 more to use. Crap Carrier engineering

    What i originally did was drop the actuator down one gear then reversed the action of the actuator. This lasted awhile till that gear broke. It took a long time tracking down the repair kit part numbers for this problem, but all in all it's done and takin care of
