Power surge- garage door opener

A power surge, possibly from lightning, has knocked out my garage door opener. The safety beam no longer works but the door will open and close if you keep your finger on the button. Is there a way to test the safety beam light to rule that as the damaged part? Any other suggestions on what to look for? Thanks

You don't need to test it. It is by design that the door works if you hold the button in when the safety beam is not working properly.

In your case, the beam is not working. Either the wires have come undone or the transmitter or receiver is broken. Do the lights on the transmitter and receiver work? If one light is out then that unit is damaged.

neither light works. What voltage should I read at the transmitter?
