The LiftMaster 41A6104 Cable Tension Monitor is a genuine replacement part designed for use with LiftMaster 3800 Garage Door Openers. This component plays a crucial safety role by monitoring cable slack—if excessive slack is detected, the door will automatically reverse, preventing damage and improving operator reliability.
A faulty cable tension monitor may trigger the LED light to flash 9 times and cause the door to reverse even when no obstruction is present. In this case, replacing the part will restore safe, reliable operation.
This replacement part can be installed without removing the opener from the wall, making the process fast and straightforward for homeowners or technicians. Proper installation ensures the garage door opener functions correctly in the down direction.
