LiftMaster K94-36531 Reset Switch with ID Resistor Kit
The LiftMaster K94-36531 is a factory reset switch with an integrated ID resistor used in select LiftMaster DC gate operator control systems. This type of switch is more than a simple push button. The ID resistor helps the operator electronics recognize the correct service configuration, so matching the correct kit matters when a reset switch has failed, a cable has been damaged, or an enclosure service has disturbed the original reset wiring. Common replacement reasons include a broken reset button, damaged leads, moisture-damaged switch contacts, or a control system that will not reset properly after a fault. Because similar LiftMaster reset switch kits can look alike, this part should be matched by the exact K94-36531 number and the operator parts diagram.
Compatible With
Select LiftMaster CSL24 gate operator applications; some parts listings also associate this reset switch family with various LiftMaster residential and commercial DC gate operators where the parts diagram calls for K94-36531. Verify the original part number, switch connector, and ID resistor requirement before ordering.

Technician Note
Do not substitute a plain reset switch for a reset switch with an ID resistor. The control board may not recognize the circuit correctly.
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 the ID resistor do on the K94-36531 reset switch?
The ID resistor is part of the operator identification and reset circuit. It helps the LiftMaster control system recognize the correct reset switch assembly instead of reading it as a generic switch.
Is K94-36531 used on every CSL24 operator?
No. It is commonly associated with select CSL24 family operators, but suffix, generation, and parts diagram should be checked before ordering.
Can I replace K94-36531 with a regular push button?
No. A regular push button does not include the correct ID resistor and may create reset or fault recognition problems.
What should be checked before replacing this switch?
Match the original part number, connector style, wire routing, and operator model. Look for water damage or broken wiring around the reset switch location.
Should power be disconnected before replacing this kit?
Yes. Gate operator service should be done with power disconnected, and a qualified gate technician should handle unsafe or unfamiliar electrical work.
