Garage Door Openers - FAQs & Troubleshooting

This usually indicates a safety sensor issue. The photo eyes at the bottom of the door tracks must be aligned and free from dirt or obstructions. If they are misaligned or blocked, the opener will only close the door when you hold the wall button down continuously.

• Check that both sensors face each other directly.
• Clean the lenses with a soft cloth.
• Look for loose or damaged wires.

If the sensors are defective, replacement infrared safety sensors may be required.

See our Wall Button troubleshooting guide for more help.

If your remote control doesn’t operate the opener, common causes include:

• Dead or weak batteries — replace with a fresh set.
• Remote lost programming — reprogram using the “Learn” button on the opener.
• Blocked signal — ensure nothing is interfering with the antenna wire on the opener.
• Defective remote — replacement garage door remotes are available.

Limited range can be caused by radio interference or a weak signal:

• Replace the battery in your remote.
• Check the opener’s antenna wire — it should be hanging down freely.
• Move or unplug nearby electronics (like WiFi routers, LED lights, or chargers) that can cause interference.
• If range is still poor, a replacement remote control may be needed.

If the opener doesn’t respond to keypad entry:

• Check the keypad batteries and replace if necessary.
• Ensure you’re entering the correct PIN.
• Reprogram the keypad using the opener’s “Learn” button.
• If issues continue, a replacement garage door keypad may be required.

This can be caused by mechanical or setting issues:

• Check for broken or weak springs — the door should be balanced manually.
• Inspect the tracks for obstructions or damage.
• Adjust the opener’s travel limits and force settings per the manufacturer’s instructions.
• Lubricate moving parts like rollers and hinges to reduce friction.

The flashing light is a warning from the opener’s safety system. It usually means:

• The safety sensors are blocked, dirty, or misaligned.
• The wiring to the sensors is loose or damaged.
• In rare cases, the logic/control board may be failing and need replacement.

Start by cleaning and realigning the sensors before considering replacement parts.

Compatibility depends on your opener’s brand, model, and frequency. Check the label on your opener for the model number and match it with the correct remote. Unsure? A universal garage door remote may also work.

Programming instructions vary by model. Most require pressing the “Learn” button on the opener and then pressing the button on your remote. For full instructions, view the product page for your specific remote control.

Weak batteries or radio interference are the most common causes:

• Replace the remote’s battery.
• Move or unplug nearby electronics (LED lights, routers, chargers) that may interfere.

Yes, most universal garage door remotes work with major brands. Always check the product listing or packaging to confirm compatibility with your opener’s model and frequency. Shop universal remotes here.

Most keypads can be reset by holding the Program button until the light blinks, then entering a new PIN. Some require reprogramming through the opener’s “Learn” button. For model-specific instructions, see the product page for your keypad.

Unplug the opener for 30 seconds, then plug it back in. For a full reset, hold the Learn button until the memory clears, then reprogram all remotes and keypads.

This often means the trolley is disengaged — check the red release cord. If it is engaged, possible causes include a stripped gear, broken chain, or belt issue. Replacement garage door opener parts & gear kits may be required.

This usually indicates an issue with the safety sensors:

• Ensure both sensors are aligned and the indicator lights are solid.
• If the lights are blinking or off, realign or replace the sensors.
