Thanks for the video. 2 questions: Do you have to take out the Actuator from it's position to test it ( i.e lots of manual work taking apart the door) Can you use a Multimeter or Continuity Tester to test?
No you don't have to take the actuator out. You just have to make sure you can get power to both leads. As far as your second question with the multimeter I'm not 100% sure on how to do that one.
Short answer is probably not. An actuator is a small relay (coil of wire) that moves a magnetic slug when power is applied. A standard multimeter doesn't apply power (voltage) to operate the actuator. If you knew the expected resistance of the coil you could check that, but otherwise you're limited to whether or not it's a short (0.1 ohms) or open (overload OL or extremely high resistance typically in the megaohms) (both of which would indicate it is bad).
I would imagine if you left it on for hours it would do something but it really doesn’t have that many moving parts so I think it will take a real long time.
