LiftMaster K180A0357 Reset Switch — Compatible CSL24 / CSW24 Gate Operators

The LiftMaster K180A0357 is the reset-switch service reference identified in supported CSL24 and CSW24 gate-operator diagrams. It is a separate control input component from the operator’s AC power switch, main board and alarm assembly. Select it by the exact model drawing and installed switch arrangement before ordering. A replacement reset switch restores the specified control function when that component is faulty; it does not correct the mechanical, wiring or protection-device problem that caused an operator to stop or enter a fault condition.

Compatibility — Models, Versions and Exclusions

Separate a Switch Fault from the Reason a Reset Is Needed

A gate may stop because of an obstruction, a protection-device fault or another condition requiring diagnosis. Repeatedly resetting the system without correcting that cause can leave the entrance unsafe or unreliable. Have the technician inspect the fault information and the switch circuit before concluding that the switch itself is defective.

Match the physical mounting and wiring to the documented replacement. Do not substitute a general-purpose button based solely on appearance, and do not bridge the circuit to conceal a damaged switch. After replacement, verify the intended reset behavior under controlled conditions and confirm that all required safety devices still stop or reverse movement as specified.

Specifications and Product Identification

Before Ordering

• Record the full operator model and existing switch identification.
• Locate K180A0357 in the matching service drawing.
• Inspect mounting, connector and wiring condition.
• Diagnose the condition that prompted the reset before returning the gate to service.

Package Contents and Separate Requirements

This offer identifies the reset switch. Confirm the current kit for any supplied lead, connector or mounting hardware. The AC switch assembly, alarm, main board and complete wiring harness are not promised as included. A diagram showing the switch near other electronics describes its installed location rather than a bundled replacement package.

Safety Warnings — Read Before Installation or Service

• WARNING: A reset can restore the ability of a gate to move. Keep people clear and use a qualified gate technician for diagnosis and replacement.
• Disconnect AC, battery and any solar power as applicable before switch or wiring service. The reset control is not a power-isolation device.
• Do not bypass safety inputs or repeatedly reset an unresolved fault to keep the entrance operating.
• Verify reset behavior, travel endpoints, reversal and every required protection device before allowing normal traffic.

Related Products and Important Differences

• LMRRUL monitored photo eye — a separate protection option only where the exact operator and control revision approve it; not a universal legacy retrofit.
• LMWEKITU monitored wireless edge kit — a separate edge communication system for approved controls and resistive edges; not a replacement for this mechanical or electrical service part.

Frequently Asked Questions

Is this the operator’s AC on/off switch?

No. Manufacturer drawings identify the reset switch separately from the AC power-switch assembly.

Will replacing it clear any gate fault permanently?

No. The cause of a fault must be diagnosed and corrected independently.

Can I use any similar-looking push button?

No. Confirm the specified switch, wiring and mounting arrangement.

Does pressing Reset make it safe to work inside?

No. Isolate all applicable power sources using the manufacturer’s service procedure before working on the equipment.
