### Door Not Opening or Closing:

**Problem:** The door does not respond to the remote control or wall button. **Solution:** Check if the power is on and the wiring is secure. Inspect the remote control and wall button for any damage or loose connections. Replace the batteries in the remote control if necessary.

### Door Stops and Reverses Mid-Cycle:

### Door Opens Partially and Stops:

**Problem:** The door opens only partially and then stops before reaching the fully open position. **Solution:** This issue may be caused by a worn or broken torsion spring or extension spring. Springs provide the tension needed to lift the door. Contact a professional to inspect and replace the springs as necessary.
