I have an older Genie IS900 garage door opener. When I open or close the garage, it powers off/ dies. After a few minutes, it’ll power back on. Unplugging it and plugging it back in also fixes it temporarily. It does have Safe-T beam sensors. The green light stays lit but red flashes three times and stays solid on the 4th time.
For the experts, could this be a sensor issue or perhaps the Genie system needs to be replaced? Any info is appreciated. Thanks!
