Genie 27092A.S LIMIT WORM DRIVE
The Genie 27092A.S is a genuine OEM limit worm drive used in the limit mechanism of select Genie residential garage door openers. It drives the limit worm gear (GE-27091A.S), which in turn rotates the limit cam assembly to set the door travel limits. The worm drive is one of 7 interrelated limit mechanism components; the remaining parts - limit wheel, limit pinion, limit cam, limit plate, and limit switch - complete the assembly. Compatible Genie models include PMX300-IC, PMX500-IC, PMX700 through PMX1200, GPS700IC, and GPS1200IC. Verify your specific model before ordering service parts for the limit mechanism.

Frequently Asked Questions
Q: What is the function of the limit worm drive?
A: The limit worm drive meshes with the limit worm gear (GE-27091A.S) to transmit rotational motion to the limit cam assembly, which sets the door's open and close travel stop positions.

Q: How many components are in the limit mechanism assembly?
A: The limit worm drive is one of seven components in the limit mechanism sub-assembly used in PMX and GPS series openers.
Q: What symptoms suggest the limit worm drive needs replacement?
A: Symptoms include the door not stopping at the correct open or closed position, the opener continuing to run after the door has reached its limit, or erratic door travel behavior.
Q: Are there any alternate or legacy part numbers for GE-27092A.S?
