LiftMaster K71-33445 Reset Switch - CSW200 and SL3000 Omni Board Operators
The LiftMaster K71-33445 is a manual reset switch used on select CSW200 and SL3000 gate operators equipped with an Omni board upgrade. In these systems, the reset switch provides a manual interface for clearing certain operator fault or alarm states after the underlying condition has been corrected. It is a small part, but it is important because the operator may not return to normal operation if the reset switch is damaged, disconnected, or not communicating properly with the control system.
This switch should be replaced only after confirming the operator model, board type, and wiring connection. Reset switches used on other LiftMaster gate operators can look similar but may have different connectors, mounting styles, or control functions. If the operator repeatedly needs resetting, inspect safety devices, entrapment conditions, accessory wiring, and control-board fault history before assuming the switch is the only issue.

Technician Note
Repeated reset events usually mean the operator is responding to a fault, entrapment alarm, accessory issue, or wiring problem. Replacing the switch without correcting the fault may not solve the problem.
Before Ordering
- Confirm the operator is CSW200 or SL3000 series with Omni board upgrade.
- Match the original switch and connector style.
- Inspect switch wiring for corrosion, loose terminals, or cabinet damage.
- Review the operator fault or alarm condition before replacing parts.
- Do not bypass the reset circuit or safety inputs to force operation.
Professional Advisory
Reset switches are tied to operator safety and control functions. If the gate will not reset or repeatedly faults, have the system inspected by a qualified gate technician.
Product Questions and Answers
What operators use the K71-33445 reset switch?
It is commonly used on LiftMaster CSW200 and SL3000 series gate operators with an Omni board upgrade.
Is this a limit switch?
No. K71-33445 is a manual reset switch, not an open or close limit switch.
Can I bypass the reset switch if it fails?
No. Bypassing reset or safety-related controls can create unsafe gate operation and should not be done.
Why does my operator keep needing reset?
Repeated reset conditions can be caused by safety device issues, obstruction events, accessory wiring problems, or control-board faults.
Is this switch used on LA400 or RSW12 operators?
No confirmed LA400 or RSW12 compatibility should be assumed; those operators use different service parts.
