How To Ajust Craftsman 1 2 Hp Garage Door Opener – Full Step-by-Step Guide
Step 1: Identify the Adjustment Screws
Locate the adjustment screws on your Craftsman opener. Most units will have two labeled dials:
- “Up Force” and “Down Force”: Controls how much force is applied during opening and closing.
- “Up Travel” and “Down Travel”: Controls how far the door travels before stopping.
These dials are usually located on the back or side panel of the opener’s motor unit.
Step 2: Ajusting the Travel Limits
Travel limits control how far the door moves when opening and closing.
To Ajust the Up Travel (Open Limit):
- Plug in the opener and press the remote.
- If the door doesn’t open fully, turn the Up Travel screw clockwise in small increments.
- Test the door after each adjustment until it opens fully.
To Ajust the Down Travel (Close Limit):
- If the door doesn’t close all the way, turn the Down Travel screw clockwise.
- Test after each small adjustment.
- If the door reverses when hitting the floor, the down limit might be set too far. Turn it counter-clockwise slightly.
Step 3: Ajusting the Force Settings
If your door stops unexpectedly or reverses, adjusting the force settings may solve the issue.
To Increase Upward Force:
- Turn the Up Force dial clockwise if the door struggles to lift.
To Increase Downward Force:
- Turn the Down Force dial clockwise if the door stops or reverses when lowering.
⚠️ Important: Do not set the force too high, as this can create a safety hazard and possibly damage the system.
Step 4: Test the Safety Reversal System
The safety reversal system is crucial in preventing accidents. After making adjustments, test it as follows:
- Place a 2×4 board flat on the garage floor beneath the door.
- Close the door.
- The door should reverse automatically when it hits the object.
If it doesn’t, recheck the force and travel settings, or consult a technician.
Step 5: Ajust the Sensor Alignment (If Necessary)
Craftsman openers come with infrared safety sensors near the bottom of each side of the door.
- Make sure both sensors are clean and aligned.
- A blinking sensor light indicates misalignment.
- Adjust until both lights are solid.
Maintaining Your Craftsman Garage Door Opener After Ajustment
Once you’ve completed the adjustments, follow these maintenance tips to keep things running smoothly:
- Lubricate moving parts like rollers, hinges, and the chain drive every 6 months.
- Check the chain tension and tighten if it’s sagging.

- Inspect the weather seal and replace it if it’s worn.

- Reset to factory settings and start over.
