LiftMaster 41A4373A Safety Sensor Kit

Product Overview

LiftMaster 41A4373 safety sensors are replacement infrared safety sensor eyes for compatible older LiftMaster and Chamberlain garage door openers with an existing safety sensor option. The kit is used to detect obstruction across the door opening and support safer automatic door operation. It is mainly associated with 1993 to late 1990s operators and fail-safe infrared eye systems. For Abu Dhabi customers, this product is suitable for maintenance, repair, and replacement where the existing garage door opener still uses the correct older safety sensor style.

Compatibility and Installation Notes

The LiftMaster 41A4373A safety sensor kit should only be used with compatible older garage door openers that already support infrared safety sensors. It is not a universal replacement for every LiftMaster opener, and it should not be confused with newer post-1997 safety sensor kits unless compatibility has been confirmed. The supplied sensors are designed to splice into existing wiring, but brackets are not included, so the existing mounting setup must be checked before installation. For safer product matching, review LiftMaster’s official replacement parts guidance and confirm the opener manual or parts diagram before fitting. Professional installation is recommended because incorrect sensor alignment or wiring can stop the opener from closing safely.
