What are some common garage door motor repairs?

Some common garage door motor repairs include replacing the main gear and replacing the control board. Both repairs are relatively simple, and parts cost between $20 and $80, as of 2016.

If there is power at the outlet, but lights do not illuminate and the motor does not start with the push of the button, a lightening strike could have affected the circuit board. Replacement with a new one takes about 10 minutes. If the unit makes grinding sounds but the door does not open and the carriage does not move, replace the plastic main gear drive. A broken main gear is the most common reason most units fail.
