If you’ve recently replaced the plastic gear in your Craftsman garage door opener, only to find that it still won’t work, you’re not alone. This is a common issue faced by many homeowners who attempt DIY repairs on their garage door openers. The problem can be frustrating, especially if you’re unsure of what went wrong. In this article, we’ll discuss the possible reasons why your Craftsman garage door opener won’t work after replacing the plastic gear, and provide step-by-step troubleshooting advice to help you get your garage door opener back in working order.
Understanding the Problem: Craftsman Garage Door Opener Won’t Work After Replacing Plastic Gear
When you replace the plastic gear in a Craftsman garage door opener, it’s typically because the original gear has worn out or stripped, a common issue with older or frequently used openers. However, if after completing the replacement, the opener still doesn’t work, there could be a variety of reasons behind the malfunction. Below are the most common causes of failure after replacing the gear.

1. Incorrect Gear Installation
One of the most common mistakes during DIY repairs is improper installation. Even though replacing the plastic gear seems simple, there are several steps that need to be done correctly to ensure that the new gear works as intended. If the gear isn’t installed correctly, it can cause the opener to fail.
2. Damaged or Worn Components
It’s possible that other components within your Craftsman garage door opener were also damaged or worn out during the replacement process. For example, a broken sprocket, motor, or even the chain could be preventing the opener from working properly. If these components were overlooked during the gear replacement, they might now be the cause of the malfunction.
3. Misalignment of the Gear Assembly
Another common reason for your Craftsman garage door opener not working after replacing the plastic gear is the misalignment of the gear assembly. If the new gear is not properly aligned with the motor or other moving parts, it can cause friction, which will prevent the system from functioning correctly.
4. Electrical Issues
After replacing the plastic gear, electrical issues could arise, preventing the opener from working. If the wiring was disturbed during the repair, or if the motor has issues, it may not provide the necessary power to operate the garage door.
5. Failure to Lubricate the Gear
Lubrication is crucial for the proper functioning of the gear system. If the plastic gear was replaced but not properly lubricated, it could create friction that hinders the opener from working. Lubrication helps the gear to move smoothly and prevents excessive wear.
How to Fix the Problem: Craftsman Garage Door Opener Won’t Work After Replacing Plastic Gear
If your Craftsman garage door opener is still not functioning after replacing the plastic gear, don’t worry! Below are the steps you can follow to troubleshoot and resolve the issue.
Step 1: Double-Check the Gear Installation
The first thing you should do is ensure that the gear was installed properly. To do this, follow these steps:
- Disconnect the Power: Always start by disconnecting the power to your garage door opener before performing any work.
- Remove the Cover: Take off the cover of the garage door opener to access the gear assembly.
- Inspect the Gear Alignment: Ensure that the new plastic gear is aligned correctly with the motor and other components, such as the chain and sprocket. Any misalignment can cause friction and prevent the system from working.
- Reassemble the Opener: Once the gear is properly aligned, reassemble the opener and test the operation.
Step 2: Check for Damaged Components
If the gear installation seems correct but the opener still won’t work, it’s time to inspect the other components for damage. Here’s what you should look for:
- Check the Sprocket: The sprocket is responsible for transferring the motor’s power to the gear system. If the sprocket is damaged or stripped, it could prevent the new gear from functioning properly.
- Inspect the Chain: Check the chain for wear and tear. If the chain is broken or too loose, it could prevent the opener from operating.
- Examine the Motor: The motor should be operating smoothly. If you hear unusual sounds or if the motor seems weak, it could be faulty and may need to be replaced.
If you discover any damaged components, you’ll need to replace them. These parts are usually available from hardware stores or online retailers that sell garage door opener parts.
Step 3: Realign the Gear Assembly
If you suspect that the gear assembly is misaligned, you can try to adjust it. Follow these steps:
- Loosen the Screws: Locate the screws or bolts that secure the gear assembly in place and loosen them slightly.
- Adjust the Gear: Shift the gear slightly so that it is properly aligned with the sprocket and the motor.
- Tighten the Screws: Once the gear is correctly aligned, tighten the screws and reassemble the opener.
Realigning the gear assembly ensures that the new plastic gear can mesh properly with the other components, allowing the opener to function smoothly.
Step 4: Check for Electrical Issues
Electrical issues can sometimes be overlooked during a repair. To check for electrical problems, follow these steps:
- Inspect the Wiring: Look for any loose or frayed wires that might have been disturbed during the repair process. Ensure that all connections are secure.
- Test the Power: Ensure that the opener is receiving power. Check the circuit breaker to ensure it hasn’t tripped, and confirm that the opener is plugged in properly.
- Test the Motor: If the motor doesn’t run or seems weak, it could be faulty. Test the motor by activating the opener and observing if it moves at all.
If you discover any electrical issues, you may need to call a professional to repair or replace the motor or wiring.
Step 5: Lubricate the New Gear
Proper lubrication is essential for the smooth functioning of the gear system. Without lubrication, the gears can experience excessive friction, which can hinder the operation of the opener. To lubricate the plastic gear:
- Use the Right Lubricant: Use a garage door lubricant or silicone-based spray. Avoid using grease or oil-based products, as they can attract dirt and grime.
- Apply Lubricant: Apply the lubricant to the gear, ensuring that it covers all moving parts. Be sure to lubricate the chain, sprocket, and any other moving components as well.
- Test the Opener: After lubricating, test the opener to see if it operates more smoothly.
Lubrication helps reduce wear on the new gear and improves the overall efficiency of the opener.
When to Call a Professional
If you’ve followed all the steps above and your Craftsman garage door opener still won’t work after replacing the plastic gear, it may be time to call a professional. A trained technician can diagnose more complex issues, such as motor failure, electrical problems, or other internal component issues that may be causing the malfunction.
While DIY repairs can save money, garage door openers are intricate systems that sometimes require professional expertise to fix. If you feel uncomfortable with the repair or can’t identify the problem, don’t hesitate to seek help.
Conclusion
Replacing the plastic gear in a Craftsman garage door opener is a common repair, but when the opener doesn’t work afterward, it can be frustrating. By carefully following the troubleshooting steps outlined in this article—checking the installation, inspecting damaged components, realigning the gear, checking for electrical issues, and lubricating the parts—you can often resolve the issue yourself. However, if the problem persists, don’t hesitate to consult a professional to ensure your opener is functioning safely and properly.
