The LiftMaster K41-0048-000 is a reset switch assembly with ID resistor for select LiftMaster heavy-duty gate operators. The reset switch allows the operator to be manually reset after certain fault or entrapment conditions, while the ID resistor helps the control system recognize the correct configuration. Because this is a model-specific HD gate part, the resistor/switch assembly should not be substituted with a generic push button.
Product Details
This part is commonly replaced when the reset button is damaged, stuck, missing, water-intruded, or not being recognized by the operator. A bad reset assembly can keep an operator locked out, make faults difficult to clear, or create intermittent operation. However, repeated reset faults usually point to an underlying safety, obstruction, wiring, or setup problem that must be corrected.

Technician Note
If the operator needs frequent resetting, do not treat the reset switch as the only problem. Check monitored entrapment devices, obstruction history, limit faults, accessory wiring, gate drag, and board fault codes.
Before Ordering Checklist
- Verify the operator parts diagram lists K41-0048-000
- Confirm the existing reset assembly uses an ID resistor style connector
- Inspect reset wiring for corrosion, cuts, or water damage
- Resolve the cause of repeated lockouts before returning the gate to service
- Test reset operation and safety devices after replacement
Professional Advisory
A reset switch should never be used to ignore repeated entrapment or obstruction faults. If faults return, have a qualified gate technician inspect the gate, safety devices, and control system.
Product Questions and Answers
What does the ID resistor do?
The ID resistor helps the HD operator control system recognize the correct reset assembly/configuration.
Can I replace this with a generic push button?
No. A generic push button does not provide the same ID resistor function and may not be recognized correctly.
Which operators use K41-0048-000?
It is commonly associated with select LiftMaster heavy-duty slide and swing gate operators when the parts diagram calls for this part.
Will this clear all gate faults?
It only restores the reset switch function. The cause of the fault, such as obstruction, safety device trouble, or wiring damage, still needs to be corrected.
Is K41-0048-000 the same as K41-0050-000?
No. K41-0050-000 is specifically referenced for HDSW24UL. Match the exact part number before ordering.
