Garage door openers like the Genie G3T-Dx provide convenience and security, but sometimes they can malfunction. A common issue users face is when the Genie G3T-Dx opens the garage door but will not close it. This problem can be frustrating, especially if you’re unsure what’s causing it.
In this article, we’ll explore why your Genie G3T-Dx opens the garage door but will not close it, how to troubleshoot the issue, and steps to fix it. We’ll also provide some expert tips to ensure your garage door opener operates smoothly.
Common Reasons Why Genie G3T-Dx Opens Garage Door But Will Not Close It
Several factors can cause this issue, ranging from sensor problems to misaligned settings. Below are the most common reasons:
1. Faulty Safety Sensors
Modern garage door openers, including the Genie G3T-Dx, come with built-in safety sensors that prevent accidents. These sensors, located near the base of the garage door tracks, detect obstacles. If the door opens but doesn’t close, a sensor issue is a likely cause.
How to Fix:
- Check for dirt, dust, or debris on the sensors and clean them.
- Ensure the sensors are properly aligned—both should have a steady LED light.
- If one sensor light is blinking, adjust its position until the light remains steady.
2. Remote Control Malfunction
The Genie G3T-Dx remote control might send inconsistent signals, causing the opener to work only in one direction.
Troubleshooting Steps:
- Replace the remote batteries.
- Reprogram the remote following the Genie G3T-Dx manual.
- Try using the wall-mounted control panel instead of the remote. If the door closes using the wall panel, the remote is likely the issue.
3. Obstruction in the Garage Door Path
If your Genie G3T-Dx opens the garage door but will not close it, an object might be blocking the path. Even small items like leaves or dirt can trigger the safety mechanism.
Solution:
- Check the garage door track and clear any debris.
- Ensure there are no loose objects near the bottom of the door.
- Inspect the rollers for obstructions or damage.
4. Limit Settings Misalignment
The Genie G3T-Dx uses limit settings to determine how far the door should open and close. If the closing limit is set incorrectly, the opener might think the door has hit the ground before it actually has.
Fixing the Limit Settings:
- Locate the limit adjustment screws on the opener unit.
- Turn the “close” limit screw slightly in the direction needed.
- Test the garage door to see if the problem is resolved.
5. Malfunctioning Garage Door Opener Motor
A worn-out motor can prevent the Genie G3T-Dx from closing the garage door, even though it opens without issue.
Signs of a Bad Motor:
- Unusual noises when operating the garage door.
- The motor stops working intermittently.
- A burning smell from the opener unit.
Solution:
- If the motor is overheating, unplug the opener and let it cool down.
- Check the power connections and ensure they are secure.
- If the motor is faulty, it may need to be replaced.
6. Issues with the Trolley or Drive System
The trolley system, which moves the door up and down, may be stuck or disengaged. If your Genie G3T-Dx opens the garage door but will not close it, the trolley may not be engaging properly.
Troubleshooting Steps:
- Inspect the trolley to see if it’s stuck or off-track.
- If your opener has a manual release cord, make sure it hasn’t been pulled accidentally.
- Lubricate the drive system to ensure smooth operation.
How to Reset Your Genie G3T-Dx Garage Door Opener
If none of the above solutions work, resetting the opener can help. Here’s how to do it:
- Unplug the garage door opener from the power source.
- Wait for about 30 seconds before plugging it back in.
- Press and hold the “Learn” button on the opener until the LED light blinks.
- Reprogram your remote and wall-mounted control panel following the Genie manual instructions.
Preventing Future Issues with the Genie G3T-Dx
To avoid running into this issue again, follow these maintenance tips:
- Regularly clean the sensors to prevent obstructions.
- Check the garage door track for debris and clear it when necessary.
- Lubricate the moving parts to reduce wear and tear.
- Test the garage door balance to ensure smooth operation.
When to Call a Professional
If you’ve tried all the troubleshooting steps and your Genie G3T-Dx still opens the garage door but will not close it, it may be time to call a professional. Seek help if:
- The motor is making loud grinding noises.
- The opener stops working altogether.
- You notice frayed or broken cables.

If your Genie G3T-Dx still won’t close the garage door after trying these steps, consider resetting the opener or contacting a professional for further assistance. Keeping your garage door opener in good condition with regular maintenance will also help prevent similar issues in the future.
