LiftMaster K180A0357 Replacement Reset Switch
The K180A0357 reset switch is a service component used in select LiftMaster gate operators to restore reset-switch function at the operator. When the switch is damaged or worn, the operator may not respond properly after a reset command, or the switch may feel loose, stuck, or unreliable. This part is not a fix for every fault condition; it only replaces the physical reset switch assembly.
Compatibility is commonly associated with the CSL24, CSW24, RSL12, and RSW12 families. Those families include several suffixes and UL generations, so the safest method is to match the switch by parts diagram and original harness style. If the operator continues to trip or fault after switch replacement, the underlying cause should be diagnosed instead of repeatedly resetting the system.

Technician Note
If the reset switch is being replaced because the operator repeatedly faults, diagnose the cause of the fault. Entrapment device issues, gate binding, battery problems, motor load, or board faults can all create reset complaints.
Before Ordering
- Confirm the operator family and suffix
- Verify K180A0357 in the parts diagram
- Compare the mounting and wiring style to the original switch
- Disconnect power before service
- Do not bypass fault or entrapment circuits to keep the gate running
Professional Advisory
Disconnect power before servicing the operator. For high-voltage wiring, three-phase equipment, moving gate hardware, or uncertain diagnosis, use a qualified gate technician. Do not bypass entrapment protection or safety devices to make an operator run.
Product Questions & Answers
What does the K180A0357 reset switch do?
It replaces the physical reset switch used on select LiftMaster gate operators to restore reset-switch function.
Which model families use this reset switch?
Common references include CSL24, CSW24, RSL12, and RSW12 slide and swing gate operator families, but exact suffixes should be verified by diagram.
Will this fix an operator that keeps tripping?
Only if the reset switch itself is faulty. Repeated tripping usually requires diagnosis of the operator, gate movement, accessories, batteries, or safety devices.
Can I bypass the reset switch?
No. Bypassing switches or safety-related circuits is not recommended and can create unsafe operation.
Is this a high-voltage repair?
The switch is an electrical component. Power should be disconnected, and a qualified technician should handle wiring or uncertain fault diagnosis.
