Understanding Liftmaster Error 1-6

If your Liftmaster garage door opener is flashing or blinking 1-6 times in a sequence, it's indicating a specific issue that needs attention. This error code specifically means that your garage door is coasting after coming to a complete stop, which can potentially cause safety issues and damage to your door system.

Symptoms

  • Door continues to move slightly after the opener stops
  • LED light flashes 1-6 times in sequence
  • Inconsistent stopping positions

How to Fix Error 1-6

Step 1: Program Travel Limits

The first step in resolving this issue is to reprogram the travel limits for your garage door:

  1. Press and hold the Program button until the UP button starts flashing
  2. Adjust the UP limit using the UP and DOWN buttons
  3. Once the door is in the desired up position, press Program to confirm
  4. Repeat the process for the down position

Step 2: Adjust Travel Limits

If programming alone doesn't solve the issue, you may need to fine-tune the travel limits:

  1. Check if the door is stopping exactly at floor level
  2. Make small adjustments to prevent over-travel
  3. Test the door several times to ensure consistent stopping

Step 3: Professional Balance Check

If the issue persists after trying the above steps, it's likely that your door needs professional balancing. An unbalanced door can cause:

  • Inconsistent operation
  • Strain on the opener system
  • Premature wear of components

⚠️ Important Safety Note

While the first two steps can be performed by homeowners, door balancing requires professional expertise. Attempting to balance a garage door without proper training can be dangerous and may result in serious injury.

Prevention Tips

To prevent this error from recurring:

  • Schedule regular maintenance checks
  • Listen for unusual noises during operation
  • Keep tracks clean and properly lubricated
  • Check for loose hardware monthly
