Why does my garage door opener hum but the door does not move? There are several potential reasons for the garage door opener to hum and the door does not move. The trolley may be stuck on the stop bolt or stop tab. There may be stripped gears, a stripped rack, a bad capacitor, or motor. To prevent possible SERIOUS INJURY OR DEATH from electrocution, disconnect ALL electric and battery power (if your opener has the EverCharge standby power) BEFORE performing ANY service or maintenance. To resolve humming issues for a chain or belt drive
If the garage door opener hums twice: Check the trolley and ensure it is not stuck on the stop bolt or stop tab. See How do I get the trolley off the stop bolt or stop tab? Remove the metal cover and inspect the capacitor. Look for oil or swelling, these are telltale signs of a failed capacitor. If the capacitor is replaced and the humming has not been resolved, replace the motor. If the garage door opener hums for about 30 seconds: Ensure the door is connected to the garage door opener. Use the emergency release handle to reconnect the door. See How can I disconnect the garage door opener to manually open or close my garage door? Check the belt or chain to be sure it has not fallen off the sprocket. After re-installing the chain or belt back on to the sprocket, ensure to check your owners manual on setting the tension to the chain or belt. If the belt/chain is connected properly, remove the metal coverto inspect the gears. If you see white plastic shavings inside the unit, or the gears appear to be worn or stripped, replace the gears.
