Your Liftmaster garage door remote will open but not close—what now? While this may seem like an unusual and frustrating problem, it’s surprisingly common. Homeowners across the country report this exact issue, and the good news is: it’s usually easy to fix.
When your Liftmaster garage door opens with the remote but won’t close, it often points to sensor, wiring, or safety system issues. Fortunately, you don’t need to be a garage door technician to figure this out.

In this article, we’ll explain why your Liftmaster garage door remote will open but not close, how to troubleshoot it effectively, and steps to prevent this issue from recurring in the future.
Why Your Liftmaster Garage Door Remote Will Open But Not Close
This problem is most often related to safety sensor misalignment, signal interference, or a faulty wall control setup. Let’s explore the most common reasons for this malfunction.
1. Safety Reversing Sensors Are Blocked or Misaligned
By far the most frequent cause of a garage door that opens but won’t close is a misalignment or obstruction of the photo-eye safety sensors.
These sensors sit on either side of the garage door, near the floor, and shoot an invisible beam across the threshold. If anything blocks that beam—or if the sensors aren’t properly aligned—the garage door opener won’t close the door using the remote.
✅ What to check:
- Ensure nothing (leaves, tools, dirt, spider webs) is blocking the sensor lenses.
- Look at the LED lights on the sensors. If one or both lights are blinking or off, realign them until both are solid.
- Gently clean the sensor lenses with a microfiber cloth.
2. Wiring Issues or Loose Connections
The safety sensor system relies on delicate low-voltage wiring. Over time, especially in damp or high-traffic garages, these wires can become loose or corroded.
✅ Inspect the wires:
- Look for frays, cuts, or signs of wear.
- Make sure all connections at the garage door opener terminals and at each sensor are tight and secure.
3. Wall Control Panel Overrides Remote Operation
If the wall control panel has a lock feature enabled, it might block the garage door from closing via the remote but still allow opening.
✅ Check the wall control:
- Press and hold the “lock” button for a few seconds until the indicator light changes or turns off.
- Try the remote again.
4. Garage Door Opener Force Settings Are Too Low
Sometimes, the “down force” setting on your opener is too low. This causes the opener to think there’s an obstruction when closing—even if nothing is there.
✅ How to adjust:
- Locate the force adjustment dials on the back or side of the opener motor unit.
- Increase the down force slightly and test operation.
- Refer to your Liftmaster user manual for exact steps.
5. Programming or Logic Board Errors
If your Liftmaster opener’s logic board (the internal computer) is malfunctioning, it may not properly respond to the “close” command.
✅ Reset the opener:
- Unplug the garage door opener for 30 seconds.
- Plug it back in and re-test with the remote.
- If the problem persists, the logic board may need replacement.
Step-by-Step Troubleshooting: Liftmaster Garage Door Remote Will Open But Not Close
Follow this simple checklist to identify and resolve the issue:
✅ Step 1: Confirm That the Door Works with the Wall Button
Try using the inside wall control. If the door closes with the wall button but not with the remote, the issue is likely with the sensors, remote, or lock mode.
✅ Step 2: Check Safety Sensor Alignment
- Both sensor LED lights should be lit.
- If not, gently move the sensors until both lights are on.
- Tighten the mounting brackets to secure alignment.
✅ Step 3: Clean the Sensor Lenses
Dust, cobwebs, or condensation can interfere with the sensors. Wipe both lenses clean with a soft cloth.
✅ Step 4: Test the Remote Again
Try closing the door using the remote while watching the sensor LEDs. If the lights blink or go out during the attempt, misalignment is still an issue.
✅ Step 5: Disable the Lock Feature
Press and hold the lock button on the wall control for 5 seconds. The blinking LED light should stop, indicating it’s deactivated.
✅ Step 6: Reset and Reprogram the Remote
If you’re still stuck, try reprogramming your Liftmaster remote:
- Press the “Learn” button on the opener.
- Within 30 seconds, press the remote button.
- Test to see if the issue is resolved.
Tips to Prevent the Problem from Happening Again
Once you’ve fixed the issue, take the following steps to make sure your Liftmaster garage door remote continues to work correctly.
1. Regularly Clean and Align Safety Sensors
Include sensor checks in your seasonal home maintenance. A quick lens wipe and LED check can save hours of frustration later.
2. Protect Sensor Wiring from Damage
Use cable covers or clips to prevent wires from being pulled, pinched, or exposed to moisture.
3. Avoid Remote Battery Drain
Low-voltage remote batteries can cause weak signals. Replace batteries every 6–12 months or sooner if range starts to decrease.
4. Use a Surge Protector for the Opener
Power surges can fry the logic board. Using a surge protector helps safeguard against unexpected failures.
5. Upgrade to Liftmaster Security+ 2.0
If your opener is more than 10 years old, upgrading to Security+ 2.0 technology provides better reliability, security, and fewer false signals.
When to Call a Professional
If you’ve gone through every step and the Liftmaster garage door remote still won’t close the door, it may be time to bring in an expert.
You might need:
- A new circuit or logic board
- Replacement safety sensors
- Or a full opener upgrade, especially if yours is older or lacks rolling code technology
Real-Life Customer Example
Sarah from Dallas, TX, had this exact issue. Her Liftmaster garage door would open just fine but refused to close with the remote. After a week of manually using the wall button, she checked the sensors and found one was barely off alignment. With a quick adjustment, both sensor lights came back on—and the problem vanished.
Moral of the story? Check the simple stuff first!
Final Thoughts
Dealing with a Liftmaster garage door remote that will open but not close can be confusing, but it’s rarely a major issue. In most cases, a misaligned safety sensor or activated wall control lock is to blame. With a few quick adjustments and basic checks, you can restore full functionality to your garage door system.
Remember:
- Start with the sensors.
- Check the lock button.
- Reprogram or reset if necessary.
- Don’t hesitate to call a technician if the issue persists.
A reliable garage door remote adds convenience and security to your daily life. Don’t let a minor glitch keep you stuck. Get it fixed—and enjoy peace of mind.
