How to Adjust a Craftsman Garage Door Opener
A garage door opener is a handy device that makes entering and leaving your garage much easier.
But what happens when it’s not working as it should be? To help ensure your garage door’s safe and smooth operation, it’s important to adjust it periodically.
Here, we’ll take you through the process step by step.
Setting the Door’s Travel Limits
The first step in adjusting your Craftsman garage door opener is ensuring the travel limits are set properly. To do this, simply run your garage door through a complete cycle of opening and closing.
If you notice any issues, use the limit adjustment screws on the garage door monitor to make adjustments. Remember that one turn of the screw usually equates to about 2 inches of door travel.
Adjust the Force
The next step is to adjust the upward and downward force of the garage door. Fine-tune the power using the screws on the garage door monitor until the door opens and closes correctly.
Once you’ve set the force, test the door by opening and closing it. If you can stop the door with your hands while it’s in operation, you’re good to go. If not, continue adjusting the force until the door stops when you interrupt it with your hands.
Why is adjusting the force so important? The door may crush anything while closing if the downward force is too strong.
On the other hand, if the upward force is too weak, the door won’t open all the way, trapping your vehicle inside.
Test the Safety Reversal System
- Start with adjusting the door.
- Once that is done, place a flat two-by-four under the open door.
- Close the door to see if it reverses when it comes into contact with the board. If it stops without reversing, increase the down limit until it passes the test.
Test the Protector System
Finally, it’s time to test the Protector System. If the system works properly, the door should move less than an inch before stopping, and the opener lights will flash.
While the door is in the up position, place a box in the door’s path to block the eye sensor. Then, use your remote to close the door.
Maintaining Your Craftsman Garage Door Opener: Step-by-Step Guide
Do you want your garage door opener to work smoothly and reliably? Then, it’s important to take care of it properly. With these five easy steps, you’ll keep your Craftsman garage door opener in tip-top shape.
Step 1: Sensor Check-Up
The first step to maintaining your opener is to inspect the sensors. These sensors are located at the bottom of the opener and help prevent the door from hitting anything.
To see if they’re working, shine a flashlight on them and observe if the lights turn on. The sensors may be dirty or poorly aligned if the lights don’t turn on. To fix this, clean the sensors and adjust their position until the lights activate.
Step 2: Lubricate the Moving Parts
Next, it’s time to give the moving parts of your opener a little love. This includes the chain, gears, and bearings. Simply apply a few drops of oil to these parts and run the door up and down a few times to spread the oil evenly.
Step 3: Check the Door’s Balance
Step three is about checking the door’s balance. If the door is off balance, it can put extra stress on the opener and make it wear out faster. To check the balance, disconnect the opener and try lifting the door halfway up by hand.
If the door stays put, it’s balanced. But if it starts to fall, it’s time to make some adjustments.
Step 4: Tighten Any Loose Screws
In step four, we’ll be tightening any screws that have become loose over time. Loose screws can cause the opener to work less efficiently, so tightening them up is important. Use a screwdriver to tighten any screws that have become loose.
Step 5: Replace the Remote’s Battery
Finally, it’s time to replace the battery in the remote. Over time, the battery can lose its charge and stop the opener from working. To replace the battery, simply remove the old one and add a fresh one.
