Is your Craftsman garage door opener acting up? If you’ve ever experienced the frustration of your garage door not closing all the way, you know how inconvenient it can be. A garage door opener that won’t lower the door completely can be a sign of an underlying problem, whether it’s a simple fix or a more complex issue. In this article, we’ll discuss the common causes behind why a Craftsman garage door opener won’t go down all the way and how to troubleshoot and fix the issue yourself.
Understanding the Problem: Craftsman Garage Door Opener Won’t Go Down All the Way
If your Craftsman garage door opener won’t go down all the way, it means that there’s an obstruction or malfunction preventing the door from completing its full range of motion. Before diving into troubleshooting steps, it’s important to understand why the door might not be closing fully. Several factors could be at play, ranging from mechanical problems to sensor issues or even settings problems. Let’s look at the most common reasons for this issue.
1. Misaligned or Dirty Safety Sensors
One of the most common reasons for a Craftsman garage door opener to stop working properly is misaligned or dirty safety sensors. Modern garage door openers are equipped with sensors that detect obstacles in the door’s path. These sensors prevent the door from closing if they detect anything in the way, ensuring that the door doesn’t close on a person, car, or object.
If the sensors become misaligned, dirty, or blocked by debris, they may incorrectly signal that something is obstructing the door, causing it to stop before it fully closes.
2. Faulty or Worn-Out Springs
Garage door springs are essential components that assist in the lifting and lowering of the door. If the springs are broken, damaged, or worn out, they can prevent the door from moving correctly. The door may struggle to go down all the way or may get stuck midway through the process. A broken spring can also cause the door to fall abruptly or make an alarming noise during operation.

3. Obstruction in the Track or Door Path
Sometimes, a simple obstruction can cause your Craftsman garage door opener to malfunction. Small objects, debris, or dirt along the track or path can interfere with the movement of the door. This can make the opener stop functioning properly, especially if it encounters something blocking the way.
4. Incorrect Limit Settings
Garage door openers come with adjustable limit settings that control how far the door should travel before stopping. If these settings are off, your door may not close fully. This can happen if the limit switch gets bumped or if the opener is not calibrated correctly. This issue can often be resolved by adjusting the limit settings.
5. Issues with the Door’s Balance
If your garage door isn’t properly balanced, it could affect the opener’s performance. A door that’s too heavy on one side can cause the opener to stop before the door reaches its closed position. This might be caused by uneven spring tension, a misaligned door, or even damaged parts within the door system.
How to Fix the Craftsman Garage Door Opener That Won’t Go Down All the Way
If you’re dealing with a Craftsman garage door opener that won’t go down all the way, there are several troubleshooting steps you can take before calling a professional technician. Here are the steps to follow:
Step 1: Check the Safety Sensors
Safety sensors are located near the bottom of the door track on either side of the garage door. To check the sensors, follow these steps:
- Inspect the Sensors: Make sure the sensors are aligned correctly. The sensors should face each other with no visible obstructions.
- Clean the Sensors: Use a soft cloth to clean the sensors. Dirt and debris can obstruct the sensor’s ability to detect objects, causing the door to malfunction.
- Check for Blockages: Make sure nothing is in the path of the sensors, including leaves, dirt, or other debris. Even small obstacles can prevent the door from closing properly.
If the sensors appear to be misaligned or dirty, this might be the cause of your problem. Once cleaned and realigned, test the door again to see if it closes properly.
Step 2: Inspect the Springs and Tracks
A broken or worn-out spring can significantly impact the performance of your Craftsman garage door opener. Here’s how you can check for issues:
- Visual Inspection: Look for any visible signs of damage, such as broken or stretched springs.
- Test the Springs: Try to lift the door manually. If the door feels heavy or difficult to lift, this could be an indication that the springs are worn out or broken.
- Check the Tracks: Examine the tracks to ensure there’s no debris, rust, or other obstructions that could be causing resistance. Make sure the tracks are straight and aligned properly.
If you discover a broken spring or damaged track, it’s best to call a professional garage door technician, as these repairs can be dangerous and require special tools.
Step 3: Check for Obstructions in the Door Path
Before continuing with troubleshooting, ensure that there is nothing blocking the door’s path. Even small objects or debris can cause the opener to stop prematurely.
- Clear the Path: Remove any objects or debris that may be blocking the tracks or the door’s movement.
- Check the Floor and Tracks: Look for any obstacles that could be interfering with the door’s ability to move down smoothly.
Once you’ve cleared the area, test the door again to see if it will close all the way.
Step 4: Adjust the Limit Settings
If your Craftsman garage door opener still won’t close properly, it could be due to incorrect limit settings. These settings control how far the door travels before stopping. To adjust the limit settings:
- Locate the Limit Screws: These screws are usually located on the side or back of the motor unit of your opener.
- Adjust the Down Limit: Turn the down limit screw in small increments to adjust the door’s travel distance. Clockwise adjustments will increase the distance, while counterclockwise adjustments will decrease it.
- Test the Door: After adjusting the settings, test the door to see if it will now close completely.
Step 5: Check the Door’s Balance
An unbalanced garage door can cause operational issues. To check the balance of the door:
- Manually Lift the Door: Disconnect the opener by pulling the emergency release cord. Try to lift the door manually and observe how it moves.
- Check for Resistance: If the door feels uneven or difficult to lift on one side, it could be a sign of an imbalance.
- Adjust the Springs: If the door is unbalanced, the springs may need to be adjusted. This can be dangerous and should be done by a professional if you’re not experienced.
When to Call a Professional
While many of the issues mentioned above can be resolved by a handy homeowner, some problems, such as broken springs or serious track issues, require professional assistance. If you’ve gone through these troubleshooting steps and your Craftsman garage door opener still won’t go down all the way, it may be time to call a professional technician.
A trained technician will have the right tools and experience to diagnose and fix more complex issues safely.
Conclusion
A Craftsman garage door opener that won’t go down all the way can be a frustrating issue, but it’s usually caused by a misaligned sensor, a broken spring, an obstruction, or an issue with the door’s limit settings. By following the steps outlined in this article, you can troubleshoot and fix the problem yourself, saving time and money. However, if the issue persists or you’re unsure about making repairs, don’t hesitate to call a professional to ensure your garage door opener is functioning properly and safely.
