Ryobi opener display shows E5 and the motor hums briefly but the door does not move.

Safety first: Disconnect power immediately if the motor hums without movement to avoid overheating. Do not continue to run a stalled opener.

• 1. Disengage the opener: Pull the emergency release cord to disconnect the trolley from the door. Try to operate the opener with no load. If the motor runs smoothly and the chain/belt moves, the problem is with the door, not the opener.
• 2. Check door movement: With the opener disengaged, manually open and close the door. If it is heavy, jerky, or stuck, contact a garage door professional to service springs, cables, and tracks.
• 3. Inspect drive system: Remove the Ryobi opener cover (with power disconnected). Check the internal drive gear and sprocket for stripped teeth or broken parts. Replace the gear kit if damaged.
• 4. Check motor capacitor (if present): Some Ryobi models use a start capacitor mounted inside the head. Look for bulging, leaking, or burned components. Replace the capacitor with an identical Ryobi-rated part if defective.
• 5. Test after reassembly: Reassemble the opener, restore power, and test with the door reconnected. If E5 returns and the door moves freely by hand, the motor or control board may require replacement by a qualified technician.
