LiftMaster K94-36894 LA500 Metal Box with Reset Switch
The LiftMaster K94-36894 is a metal box with reset switch assembly used on select LA500 swing gate operator installations. The enclosure protects the reset switch and related wiring from physical damage and weather exposure while keeping the reset function accessible for service. This part is commonly replaced when the metal box is rusted, damaged, missing, or when the reset switch and enclosure assembly need to be restored after service work. Because LA500 operators may vary by package, revision, and control-box layout, the original enclosure style and reset switch routing should be compared before ordering. This is an enclosure/switch service part, not a complete LA500 control board or full control box assembly.
Compatible With
LiftMaster LA500 and LA500PKGUL style swing gate operator applications using the metal box with reset switch assembly. Fitment depends on LA500 control-box generation and layout.

Technician Note
Do not confuse this with a full LA500 control box or plastic enclosure kit. K94-36894 is the metal box with reset switch assembly.
Before Ordering
- Match the manufacturer part number on the original component whenever possible.
- Confirm the operator model, model suffix, and generation before ordering.
- Compare connector style, wire count, battery size, enclosure layout, and harness routing where applicable.
- Use the LiftMaster parts diagram as the final fitment reference when model listings conflict.
- Do not bypass monitored safety devices, reset circuits, interlocks, or fault-protection wiring.
Professional Advisory
Gate operator wiring, battery, reset switch, and enclosure repairs should be completed with power disconnected and with the gate secured from unexpected movement. If the operator has high-voltage wiring, damaged insulation, missing safety devices, water intrusion, or repeated fault conditions, have the system inspected by a qualified gate technician before returning it to service.
Product Q&A
What does K94-36894 include?
It is commonly listed as an LA500 metal box with reset switch assembly. Exact hardware should be verified by the current product listing.
Is this a complete LA500 control box?
No. It is not the complete control board, transformer, batteries, or full control panel assembly.
Which operator is this most commonly used with?
It is most commonly associated with LiftMaster LA500 and LA500PKGUL swing gate operator applications.
Why replace the metal reset switch box?
Replacement is common when the enclosure is damaged, rusted, missing, or the reset switch assembly no longer works correctly.
Can it be used on LA400 or LA412?
Do not assume so. LA400, LA412, and LA500 service enclosures differ and should be checked by parts diagram.
