Liftmaster 041ASWG-0310, KIT,SVC,CAPACITOR,25#F,250V,FLEXABLE
LiftMaster 041ASWG-0310 is a service replacement capacitor used in the motor circuit of select LiftMaster gate operator systems. In the field, this is the type of part a technician looks at when the operator has power but the motor struggles to start, runs weakly, hums, or behaves differently under load than it does with the gate disconnected. A capacitor is not a universal electrical part; the microfarad rating, voltage rating, lead style, and available space inside the operator matter.
This item is identified as a 25uF, 250V flexible capacitor service kit. The flexible style is used where the capacitor must fit into a specific operator housing or service location without stressing the leads. Before ordering, compare the number on the original capacitor and check the LiftMaster parts diagram for the exact operator model. If the original capacitor failed from heat, water intrusion, rodent damage, or a binding gate, the underlying cause should be corrected so the replacement does not fail early.
Compatible With
- Select LiftMaster gate operator systems that use a 25uF, 250V flexible capacitor service kit.
- Various LiftMaster gate operators when the parts diagram calls for 041ASWG-0310 or the original capacitor matches the same rating and style.
- Often associated with LiftMaster swing gate actuator service parts, but not every LA, CSW, RSW, or commercial gate model uses this capacitor.
- Verify the original capacitor label, motor rating, and operator parts diagram before treating it as interchangeable.
Compatibility note: LiftMaster service parts should be matched by model number, original part number, finish, connector style, voltage rating, or the official replacement parts diagram. Similar-looking parts are not always interchangeable.

Technician Note
Before replacing this part, check the surrounding hardware, wiring, enclosure, actuator, or receiver components that could have caused the original failure. On gate and access-control equipment, water intrusion, loose mounting, rodent damage, binding gates, and incorrect previous repairs often create repeat failures.
Before Ordering Checklist
- Confirm the manufacturer part number on the old part or in the parts diagram.
- Match the installed model, series, finish, voltage, cable length, connector, or mechanical style as applicable.
- Inspect nearby wiring, brackets, covers, fasteners, seals, and mounting points for damage.
- Do not substitute a similar-looking LiftMaster part unless the model-specific parts diagram supports it.
- For electrical or moving-gate repairs, disconnect power and use a qualified gate or access-control technician when needed.
Professional Advisory
Gate operators and telephone entry systems can involve moving gates, stored force, low-voltage controls, and line-voltage power sources. Do not bypass safety devices or force a gate system to run with damaged wiring or missing covers. If the system has unsafe movement, repeated faults, or electrical damage, have the installation inspected by a qualified technician.
Product Questions & Answers
What does the LiftMaster 041ASWG-0310 capacitor do?
It helps the motor circuit on select LiftMaster gate operators start and run correctly. A weak capacitor can cause sluggish movement, humming, stalling, or a motor that will not start under load.
Is 041ASWG-0310 used on every LiftMaster swing gate operator?
No. It is listed as a 25uF, 250V flexible capacitor service kit for various LiftMaster gate operators, but the installed operator parts diagram should be checked before ordering.
Can I replace this capacitor with a different microfarad rating?
No. The microfarad and voltage rating should match the original service part or the operator parts list. Using the wrong capacitor can damage the motor or create unreliable operation.
What related part numbers should I search for?
Common related references include 041ASWG-0310, 41ASWG-0310, LM-041ASWG-0310, and descriptions such as 25uF 250V flexible capacitor kit.
Should a technician install this part?
A qualified gate technician is recommended when the repair involves motor wiring, electrical testing, or a gate that moves unpredictably. Power should be disconnected before service work.
