I struggled with the same issue at our home for years. Sometimes I thought the sensor was inadvertently bumped while wheeling out the garbage bins. Sometimes the sensor would work after a few cycles. I would unwrap and rewrap the wire connections, try turning the mount, turning power on and off--all of these would work for periods of hours or months.
Eventually I replaced the sensors. The were less than $17 on Amazon (which surprised me) and have not had a reoccurrence in several years. Worked right away.
These were for a Chamberlain opener--but you can probably locate the sensors for your unit for the same price?
Good luck--it was real frustrating...
