The only electrical garage door I have fixed was about fifteen years
ago. It used a low voltage motor from a trickle charge battery. No
relays were used, the control was all electronic. My involvement was,
despite it being maintenance free, it all stopped working one day. All
I did was tighten up the battery contacts.
