Hey,

I have been trying to solve my climate control problem and discovered the actuator wasn't even plugged in for some reason (no wonder the heat didn't work). I plugged it in and have been playing with it, but I noticed that with the **** in one full direction makes the actuator look like this (below), and in the other full direction hits the casing and binds. Clearly something is off and I'm wondering how to take the motor apart and adjust the peg that moves the door.

Any ideas?

The actuator motor is not a serviceable part, door flap arm is probably broken too.

The door seems to move fine by hand. How would you tell if that's broken?

Try this....

The Blend-Air Door only turns 90 degrees full travel. Viewing the bottom of the actuator, Full Clockwise is COLD (Blue), Full Counter Clockwise is HOT (Red).

When you are going to install an actuator assembly, plug it in to the connector first before attaching it to the Blend-Air Door pivot shaft. Operate the actuator full travel hot then cold, Stopping at Cold (blue), turn the Blend-Air Door pivot shaft fully Clockwise, then install the actuator assembly. Ops check it for full travel Hot and Cold. You should see the Intermediate Drive Shaft turn in the in the appropriate directions.

Makes sense but that doesn't solve the lack of travel of the actuator motor. If it doesn't go full hot and full cold without binding that seems to be the issue.

Thanks!

The door is binding? Replace door.
actuator is binding? Replace actuator, cheap at az.

Have you tried the installation procedures above or are you just speculating that it won't work.

If you think the motor is defective, replace it.
