Troubleshooting Common Issues
Now that you're equipped with the necessary safety precautions, let's explore some common problems you might encounter with your older Craftsman opener and how to fix them.
1. The Garage Door Opener Won't Engage
Problem: You press the button on your remote or wall switch, but nothing happens. The opener doesn't make any noise, and the door remains stationary.
Possible Causes:
- Power Supply: The most common reason for a non-functioning opener is a power outage.
- Circuit Breaker: Check if the circuit breaker controlling the opener has tripped.
- Fuses: Older openers may use fuses. If you have a fuse box, inspect the fuses for any that have blown.

3. The Garage Door Opens but Doesn't Close
Problem: Your door opens smoothly but fails to close completely, leaving a gap at the bottom.
Possible Causes:
- Faulty Limit Switch: The limit switch is responsible for telling the opener when the door is fully open and closed. A faulty switch can prevent the door from closing properly.
- Jammed Door: Something might be obstructing the door's path, preventing it from closing completely.
- Safety Sensors: The safety sensors are designed to prevent the door from closing if an object is in its path. If the sensors are misaligned or dirty, they might prevent the door from closing.
Solutions:
- Adjust the Limit Switch: Locate the limit switch on the opener's motor unit. There are usually two switches – one for the open limit and one for the closed limit. Adjust the screws on the switches to ensure the door opens and closes completely.
- Clear Any Obstructions: Check for any obstructions in the door's path, such as debris or toys. Remove any obstructions.
- Clean and Align Safety Sensors: Clean the lenses of the safety sensors with a damp cloth. Ensure the sensors are aligned properly, facing each other directly.
4. The Garage Door Opener Doesn't Respond to the Remote
Problem: You press the button on your remote, but the opener doesn't react.
Possible Causes:
- Dead Battery: The most common culprit for a non-responsive remote is a dead battery.
- Malfunctioning Receiver: The receiver unit on the opener might be faulty, preventing it from picking up the signal from the remote.
- Interference: Other electronic devices, such as cordless phones, microwaves, or Wi-Fi routers, can interfere with the signal from the remote.
Solutions:
- Replace Battery in Remote: Replace the battery in your remote with a fresh one.

- Minimize Interference: Try moving the opener's receiver unit away from other electronic devices or temporarily disabling the devices to see if it resolves the issue.
5. The Garage Door Opener Doesn't Stop at the Top or Bottom
Problem: The door continues to open or close past the desired point, potentially causing damage or injury.
Possible Causes:
- Faulty Limit Switches: As mentioned earlier, the limit switches control the door's travel distance. Faulty switches can cause the door to overextend.
- Worn-out Springs: The torsion springs above the door are responsible for counterbalancing the door's weight. Worn-out springs can cause the door to travel too far.
- Track Alignment: Misaligned tracks can also contribute to the door not stopping at the correct position.
Solutions:
- Adjust Limit Switches: Locate the limit switches and carefully adjust them to ensure the door stops at the desired height.
- Inspect and Replace Springs (Professional Assistance Recommended): If the springs are worn, it's best to have a professional replace them, as they are under high tension and pose a safety risk.
- Align Tracks: Check for any bent, damaged, or loose tracks. If necessary, have a professional repair or replace the tracks.
