Re: Recirculation door thwack sound

I am a bit puzzled with the actuator motor. I've bought a new enforced actuator ( like the one shown above) but yesterday when i was trying to replace the broken part i've noticed that the actuator motor is turning a full circle onwards (when recirc is off) and a full circle backwards when recirc is on. My understanding is that actuator turning range (actuator movement) must be a quarter of a circle when recirc is off and the same backwards when recirc is on; although i am sure. Anyone can enlight me on the turning range of the actuator motor ??? Is my assumption correct ??? Maybe the unrestricted motor turning broke the actuator. Please assist

Re: Recirculation door thwack sound

Mine would also turn a full circle in each direction when I simply plugged the actuator motor in without it fully connected. Once I installed the assembly back together it would only turn a quarter circle and stop when the flap closed and turn the opposite direction a quarter circle to open the flap. The motor must sense the tension on the gear once the flap is fully open/closed and stop the rotation of the motor.

If yours is turning a full circle after you've reinstalled everything then you must not have the gears lined up or in the proper position to actuate the door properly. There is a flat part on the mating gear that needs to line up with the groove on the gear. I had to press the Recirculation button a couple of quick times to line the gears up properly.
