How do I troubleshoot my Genie garage door opener?

To troubleshoot your Genie garage door opener, follow systematic steps checking power, remote, sensors, door balance, and mechanical parts. First, check power, ensure opener is plugged in, outlet has power, breaker not tripped, and power outage not affecting, power cycle by unplugging for 30 seconds. Second, check remote battery, replace battery and try wall button, if wall button works but remote doesn't, remote battery or programming issue, reprogram using Learn button. Third, check safety sensors at bottom of door tracks, ensure LED lights steady, not blinking, clean lenses and align sensors, as misaligned sensors prevent closing. Fourth, check if door is locked or in lock mode, manual lock engaged or vacation lock on wall control activated. Fifth, check for broken torsion spring, pull emergency release cord and try lifting door manually, if heavy or won't lift, spring broken needs professional repair. Sixth, check travel limits and force settings, adjust using Set and Limit buttons on motor unit if door does not open or close fully. Seventh, check for stripped gears or broken belt/chain, motor hums but door doesn't move indicates drive failure. Eighth, check for interference from LED bulbs, replace with garage door rated LEDs. Ninth, check diagnostic codes, Genie LED blinks indicate error, count blinks and check manual. Consult manual for your Genie model for specific troubleshooting.
