A garage door that refuses to close can be frustrating and inconvenient, especially if you rely on your garage as a primary entrance to your home. If you’re facing this problem with your Craftsman garage door opener, there are several troubleshooting steps you can take to identify the cause and resolve it. This article covers common issues and solutions for Craftsman garage door opener troubleshooting when it won’t close. By following these steps, you’ll be able to get your door back in working order.
Craftsman Garage Door Opener Troubleshooting Won’t Close: Common Causes
Garage doors not closing properly is a common problem that often stems from a few key issues, including sensor alignment, remote control interference, motor problems, or wiring issues. Let’s start by exploring some typical reasons behind this issue.
1. Misaligned or Blocked Safety Sensors
The safety sensors are an essential feature for any garage door opener, especially Craftsman models. They prevent the door from closing if there’s an obstruction in its path, ensuring the safety of anyone or anything that might be in the way. However, if these sensors are misaligned or obstructed, they can stop the door from closing even when there’s no actual obstacle.
2. Issues with the Garage Door Opener Settings
Sometimes, the opener’s settings may be incorrect or need resetting. Craftsman garage door openers have a limit switch that determines how far the door closes, and if this setting is off, the door may refuse to close all the way.

3. Malfunctioning Remote Control or Wall Control Panel
If the remote or wall control panel isn’t working correctly, your garage door may not receive the signal to close. This issue could be due to battery problems, damaged buttons, or interference with other devices.
4. Problems with the Tracks or Rollers
If the garage door tracks are misaligned, or if the rollers are worn out, the door may struggle to close or stop mid-way. Regular wear and tear or lack of maintenance often lead to these issues.
5. Issues with the Garage Door Opener Motor
A faulty motor can also be the reason behind your Craftsman garage door opener not closing. Over time, the motor may weaken or malfunction, which prevents the opener from fully closing the door.
Craftsman Garage Door Opener Troubleshooting Won’t Close: Step-by-Step Solutions
In this section, we’ll discuss practical troubleshooting steps for each of the common problems listed above. Let’s explore each step in detail to help you resolve the issue.
Step 1: Check and Align the Safety Sensors
The safety sensors, located near the bottom of each side of the garage door track, play a critical role in preventing the door from closing if something is in its path. Here’s how to ensure they’re working correctly:
- Inspect the sensor lights: Each sensor should have a small light, often red or green. If one or both of these lights are off, it could mean the sensors are misaligned.
- Clear any obstructions: Dirt, cobwebs, or debris can block the sensors, so make sure the path between them is clear.
- Adjust the alignment: Try adjusting the sensors until the lights on both sides are steady. Misalignment often causes one or both lights to blink or go off entirely.
When the sensors are aligned correctly, try closing the door again. If it still won’t close, proceed to the next step.
Step 2: Inspect and Reset the Limit Switch Settings
The limit switch on your Craftsman garage door opener controls how far the door travels when closing. Here’s how to adjust it:
- Locate the limit adjustment screws: On Craftsman models, these screws are usually on the side or back of the motor unit.
- Turn the down limit screw: Turning it slightly to the right will make the door travel farther when closing. Test the door after making small adjustments to ensure it closes completely without reversing.
- Reset the opener if necessary: If the problem persists, reset your Craftsman garage door opener by following the manufacturer’s instructions.
This adjustment can often fix doors that stop before reaching the ground.
Step 3: Check the Remote Control and Wall Panel
A simple problem with the remote or wall panel could be preventing your door from closing. Here’s how to troubleshoot this issue:
- Check the remote batteries: Low batteries are a common cause of remote control failure. Replace them with fresh ones and test the door again.
- Inspect the wall panel: If the wall control panel isn’t working, check for loose wiring or other damage.
- Try the manual button: Use the manual close button on the garage door opener itself. If the door closes when you press this button, the issue likely lies with the remote or wall panel.
If the remote control or wall panel was causing the problem, this should resolve it.
Step 4: Inspect the Tracks and Rollers
Faulty or misaligned tracks and rollers can interfere with smooth operation. Here’s how to check them:
- Inspect the tracks for obstructions: Dirt, rust, or small objects lodged in the track can cause the door to stop closing.
- Check the rollers: Ensure they’re not worn out or misaligned. If the rollers are damaged, replacing them can often resolve the issue.
- Align the tracks: Use a level to check that the tracks are straight. If they’re not, loosen the mounting brackets, adjust the tracks, and retighten the brackets.
This step can help eliminate any physical barriers that may be preventing the door from closing.
Step 5: Examine the Garage Door Opener Motor
If none of the above steps resolve the issue, the problem may lie with the motor. Here’s what to do:
- Listen for unusual sounds: Grinding or humming noises can indicate a motor issue.
- Inspect the motor unit: Look for visible signs of damage, such as frayed wires or a burned-out capacitor.
- Call a professional: If you suspect a motor problem, it’s best to contact a garage door technician to handle repairs, as DIY fixes may void your warranty or cause further damage.
Maintenance Tips for Craftsman Garage Door Openers
Regular maintenance can help prevent issues with your Craftsman garage door opener and keep it functioning smoothly.
Clean the Sensors Regularly
Dust and debris can interfere with the sensor’s function. Cleaning them periodically can prevent many issues related to the door not closing.
Lubricate Moving Parts
Lubricating the hinges, rollers, and tracks can keep your garage door operating smoothly. Make sure to use a lubricant designed for garage doors.
Test the Reversal System
To ensure safety, test the auto-reverse feature every few months. Place a small object, such as a block of wood, under the door. If it doesn’t reverse upon contact, call a technician to adjust the settings.
When to Call a Professional
If you’ve followed all the troubleshooting steps and the door still won’t close, it may be time to call a professional. A qualified garage door technician can accurately diagnose the issue and carry out necessary repairs safely. Additionally, if you notice any of the following, it’s best to seek professional help:
- The motor makes unusual noises or overheats.
- The door opens and closes sporadically.
- Wiring issues are suspected.
