Possible Causes

Force settings too low, Door binding at multiple points, Weak motor capacitor, Voltage drop during operation

Safety first: Keep clear of the door while testing. Do not repeatedly force the opener against a jam.

Check door manually: Move the door by hand to ensure it travels smoothly. Correct any binding or hardware issues first.
Adjust force: Slightly increase the open and close force settings on the Mighty Mule opener per the manual.
Inspect capacitor: If the motor seems weak or slows quickly, test or replace the motor start capacitor.
Check power circuit: Avoid using long extension cords or shared circuits that may cause voltage drop.
