How Do You Adjust A Chamberlain Garage Door Opener (Step-by-Step)

Follow these steps carefully to avoid damage or misalignment.

Step 1: Locate Adjustment Screws or Controls

On most Chamberlain units:

• Look for UP/DOWN travel adjustment dials or buttons
• Usually located on the motor housing

👉 Make small changes only (¼ turn at a time).

⚠️ Important: Do not set force too high—it may cause safety risks.

Step 5: Test Safety Sensors

Safety sensors are critical for proper operation.

Check:

• Both sensors are aligned
• LED lights are solid (not blinking)
• No dirt or obstruction blocking them

If misaligned, gently adjust until both lights are steady.
