LiftMaster 575V Commercial Door Operator Brake Solenoid

Replace a failed brake-release solenoid in a compatible 575V LiftMaster commercial door operator with this genuine LiftMaster service component.

Specifications:

• Component type: Brake solenoid

• Rated voltage: 575V

• Application: Compatible LiftMaster commercial door operators

• Related part reference: 22-5751

• Brand: LiftMaster

The brake solenoid electrically releases the operator’s mechanical brake during commanded movement. A failed or incorrectly matched solenoid can prevent normal operation, cause the brake to remain engaged, or interfere with controlled stopping.

This is a voltage-specific electrical component. Confirm that the operator uses a 575V brake circuit and verify the complete operator model, phase, wiring diagram, existing solenoid number, mounting arrangement, and brake assembly before ordering. Do not substitute a 120V, 230V, or 460V solenoid.

A brake problem may also be caused by incorrect voltage, damaged wiring, a failed control component, mechanical binding, contamination, or improper brake adjustment. Diagnose the complete brake circuit before replacing the solenoid.

Installation should be performed by a qualified commercial-door technician or electrician. Disconnect and lock out all operator power before servicing. Secure the door against movement, verify correct wiring and mechanical adjustment, and test brake release, stopping performance, limits, controls, and required safety devices before returning the operator to service.

Order this LiftMaster brake solenoid only when the operator documentation specifically calls for the 575V 225751 component.
