Error code 22 happens when there is an electrical surge of some sort that affects the opener. To clear the code and get the opener working again, unplug the motor AND also remove the battery which is located in the unit. You will need to lift the light cover and take out a small screw to get to the battery. Unplug the battery and the motor and then reinstall the battery and plug the unit back in. Everything will be fine!

The problem is NOT a power surge ! It is an issue with assembly , it is a small circuit board that is called the travel modulator board. The connections are loose somewhere on that board.
Disconnect power and battery back up , remove light cover on the side where the circuit board , remove 4 screws that hold cover gentle pull cover with cicuit board out . Travel modulator is located upper right corner . Checked that the slide connections are set correctly on the terminals. There are 5 terminals on the travel modulator board , I have seen different combinations of loose ones.
