How to program travel limits on a B4505TC
You can check through the manual on Chamberlain website.
Setting travel limits on your Chamberlain garage door opener ensures safe and efficient functionality. Here’s how to do it:
1. Locate the travel limit dials on the side or rear flap of the motor unit.
2. Begin with the door closed. Press and hold the ‘Up’ button until the door reaches the desired open position, then release.
3. After the desire position, press the black button to set the limit and start the down position.
4. Next, press and hold the ‘Down’ button until the door reaches the desired closed position, then release.
5. Press the black button to set the limit. In the new models, just wait until you hear 10 clicks and the door will open and close automatically to set the force. Make sure that nothing passes through the sensors during the force learning phase.
6. Test the door to ensure it opens and closes correctly.
If you face issues, check for obstructions, ensure sensors are aligned, and confirm the motor functions correctly. For persistent problems, consult the user manual or contact Chamberlain support. Properly programmed travel limits help maintain the safe and efficient operation of your garage door opener.
