Liftmaster K23-34815, RESET SWITCH
The LiftMaster K23-34815 is a genuine replacement Reset switch / stop-reset button used in professional gate operator service work. This part is used for manual reset switch for select liftmaster commercial slide gate operators. It is the kind of component that can cause confusing field symptoms when it starts to fail because the operator may still have incoming power, but the control input, reset function, alarm circuit, or protective circuit may not respond correctly. A technician normally checks this part after confirming that the gate is mechanically free, the operator has the correct supply voltage, and the control board is not being held in a fault condition by another device.
Correct fitment matters because LiftMaster and Elite operators often use similar-looking switches, relays, alarms, and electrical accessories with different ratings, wire leads, terminals, or mounting layouts. The safest way to order this item is to match the original part number, the operator model number, and the factory parts diagram. For older commercial gate operators, also check the operator generation, control-box revision, voltage, phase, and any previous board upgrade before assuming that a visually similar part will interchange.

Technician Note
Match this part to the original component and the operator wiring diagram before installation. If the original component failed from heat, water intrusion, repeated overload, shorted wiring, or impact damage, correct that condition before installing the replacement.
Before Ordering
- Confirm the operator model number and product family.
- Match the original part number or parts diagram reference.
- Check voltage, amperage, phase, switch function, connector, and mounting style when applicable.
- Inspect the control box for water damage, burned terminals, loose wiring, or previous non-factory repairs.
- For high-voltage wiring or unsafe gate movement, use a qualified gate technician.
Professional Advisory
Electrical and safety-related gate operator parts should not be bypassed to keep a system running. If the operator has an active alarm, repeated reset condition, overload trip, or damaged wiring, diagnose the cause before returning the gate to service.
Product Questions & Answers
What does the K23-34815 reset switch do?
It provides a manual reset or stop/reset function on compatible LiftMaster commercial slide gate operators.
Which models are commonly associated with K23-34815?
Common references include SL575, SL585, SL585U, SL585UL, SL595, SL595U, and SL595UL when the parts diagram specifies this switch.
Is K23-34815 the same as K23-34815-1?
K23-34815-1 appears as a closely related stop/reset button reference. Verify the original part number and harness or mounting details before treating them as interchangeable.
Will this fix a gate that keeps going into alarm?
It may fix a bad reset button, but a repeated alarm condition can also be caused by obstruction sensing, safety-device issues, limits, motor load, or control-board problems.
Should I bypass the reset switch to test the operator?
No. Do not bypass safety or control functions. Use proper troubleshooting procedures or have a qualified gate technician inspect the system.
