I don’t have many of these and this is the first time i had this (#8) error. Tried a learn run command and now instead of re-opening four inches form close it is reopening 1 inch from close. Any recommendations (or documentation…could not find what I was looking for on the Unitec site).
Repeated tries closing the door. Sensor is fine. Buttons not stuck. Closes 90% then re-opens a dozen times then beeps non-stop. Fault code (blinks light) is #8 motor overstress.

Any recommendations would be appreciated.
