Garage door opens fine but will not close unless you hold the wall button down continuously.

Safety first: This mode is a safety fallback. Do not continue to use constant pressure as a workaround; fix the underlying sensor issue.

Steps to fix:

• Verify sensors: Confirm both safety sensors are installed, aligned, and their LEDs are solid.
• Check wiring: Repair any open or shorted sensor wires.
• Use correct sensors: Ensure you are using Chamberlain-compatible sensors for your opener model.
• Reset opener: Power cycle the opener after correcting sensor issues and test normal close operation.
