LiftMaster K23-34815-1 Replacement Reset Switch for Automatic Gate Operators
The LiftMaster K23-34815-1 reset switch is a replacement switch assembly used on select LiftMaster automatic gate operators. In many heavy-duty slide gate operators, the reset or stop/reset control is used after an operator fault, overload, or shutdown condition so the system can be returned to service after the underlying issue is addressed. This is not a universal push button for any gate operator. It is a specific replacement service part for operators whose parts diagram identifies K23-34815-1, K23-34815, or 23-34815. Customers often search for this part after the original reset button is damaged, weathered, sticking, broken at the actuator, or missing from the control enclosure. A failed switch can keep the operator from resetting properly, but repeated reset trips usually point to a deeper issue such as a binding gate, damaged drive hardware, bad limit setup, overload condition, or an electrical fault. For that reason, this part should be replaced as part of a proper diagnosis, not used to bypass the reason the operator stopped.

Technician Note
If the reset switch is being pressed often, look beyond the button. A gate that trips reset can have mechanical drag, failing rollers, incorrect limits, obstruction inputs, overload issues, or control-board faults.
Before Ordering Checklist
- Confirm the old switch is marked or diagrammed as K23-34815-1, K23-34815, or 23-34815.
- Verify the gate operator model and enclosure style.
- Compare the mounting hole, actuator/button style, and wiring terminals.
- Correct any gate binding, obstruction, or overload condition before returning the system to service.
- Do not bypass the reset or stop/reset circuit to keep a gate running.
Professional Advisory
Gate operator control circuits can include line voltage and monitored safety inputs. If the cause of a reset condition is not obvious, use a qualified gate technician rather than bypassing controls or safety devices.
Product Questions and Answers
Is K23-34815-1 the same as 23-34815?
K23-34815-1 is commonly cross-referenced with K23-34815 and 23-34815, but the operator parts diagram should be checked before ordering.
Which gate operators commonly use this reset switch?
It is commonly associated with select LiftMaster slide gate operators, including SL575, SL585, SL585U, SL585UL, SL595, SL595U, and SL595UL references where the diagram lists this switch.
Will this fix a gate that keeps tripping reset?
Only if the switch itself is faulty. A gate that repeatedly trips reset may have mechanical drag, overload, limit, obstruction, or control-board issues.
Can this reset switch be bypassed?
No. Reset and stop/reset controls should not be bypassed. The underlying fault should be diagnosed and corrected.
What should I compare before ordering?
Compare the old switch number, operator model, control enclosure, wiring terminals, and replacement parts diagram.
