Ryobi opener shows E9 and will not operate; display may be blank or flickering.

Safety first: Turn off power at the breaker before inspecting wiring. Do not open sealed electronic modules unless you are qualified.

• 1. Confirm power source: Plug a known-good device into the opener’s outlet to verify proper voltage. If the outlet is dead or unstable, have an electrician repair it.
• 2. Inspect power cord: Check the Ryobi opener power cord for cuts, kinks, or burn marks. If damaged, the opener should be replaced or professionally rewired.
• 3. Power cycle: Unplug the opener for at least 60 seconds, then plug it back in. Observe the display. If E9 appears immediately, the internal power supply is likely failing.
• 4. Check for overheating: Feel the opener housing (carefully). If it is unusually hot, leave it unplugged and contact Ryobi support or a technician. Overheating indicates internal component failure.
• 5. Replace control board or head: If the outlet and cord are good but E9 persists, the internal transformer or low-voltage power supply on the logic board is defective and the board or entire motor head must be replaced.
