Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Welcome. My name is ***** ***** would be glad to assist.
Openers do not have any master resets built inside them unfortunately.
There is no actual model number posted, so can provide the standards
Does it have a battery backup?
Have you unplugged the opener for 3-5 minutes and then plug it back in to see if it clears the problem?
Many times a hard reset cures it where the power outage triggered something in the main board.
Do you have a light on your wall button or keypad?
Have you verified the receptacle is powered?
There may be a GFCI receptacle in the garage that tripped out and needs resetting to restore power to the receptacle
Check those and let me know, we can continue to work on the situation.
