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!
