Product Description
The Genie 27095A.S is an OEM limit cam that works within the 7-component limit mechanism of Genie Stealth and ProMax PMX/GPS series residential garage door openers. Installed in pairs on the limit wheel, the limit cams rotate with the wheel and physically actuate the mechanical limit switch (27220A.S) at programmed open and close positions. The cam profile is engineered to provide a reliable, repeatable actuation point that ensures the door stops at the correct fully open and fully closed positions. When the cam loses its profile due to wear, open or close limits may become inconsistent, and replacement of the pair restores accurate limit function.

Frequently Asked Questions
Q: Why are two GE-27095A.S limit cams required per opener?
A: Two limit cams are used per opener - one for the open limit and one for the close limit. Each cam is positioned by its respective limit pinion to actuate the limit switch at the correct door travel endpoint.
Q: How does the limit cam actuate the limit switch?
A: The limit cam is positioned via the limit pinion, which is driven by the limit wheel and worm gear. As the cam rotates to the correct position, it contacts and actuates the limit switch to stop the motor.
Q: Which opener series uses the GE-27095A.S limit cam?
A: The limit cam is compatible with Stealth series openers including PMX and GPS variants equipped with cam-style limit mechanisms.
Q: What are signs of a worn or damaged limit cam?
A: Symptoms include the door over-traveling or under-traveling at open or closed positions, or the door not stopping consistently at the same point.
Q: Should I replace both limit cams at the same time?
A: Yes. When one cam shows wear, it is best practice to replace both cams as a pair since they wear at similar rates and work together to control the full travel cycle.
