230VAC Relay

This listing is specifically for the 230VAC version.

LiftMaster commercial operators may use different relays depending on their electrical configuration, including:

• 24VAC relays

• 115VAC relays

• 230VAC relays

These are not interchangeable simply because the relays appear physically similar.

Always match the original relay part number and coil voltage before ordering.

Important Compatibility Information

Before purchasing, verify:

• LiftMaster operator model

• Operator voltage

• Single-phase or three-phase configuration

• Existing relay part number

• Coil voltage

• Relay contact configuration

For this product, the replacement part should correspond to:

K24-230-5 / 24-230-5 / 242305

Do not select an electrical relay based only on its appearance or socket configuration.

When a Relay May Need Replacement

A failed or damaged operator relay may contribute to symptoms such as:

• Operator does not run

• Motor fails to activate

• Intermittent operator operation

• Relay does not energize

• Contacts fail to switch properly

• Audible relay activation without proper motor response

• Visible heat or electrical damage

These symptoms can also be caused by transformers, contactors, wiring, control circuits, overloads, motors, or other electrical components. Proper electrical diagnosis is recommended before replacing the relay.

Installation & Safety

Disconnect and lock out electrical power before servicing a commercial door or gate operator.

This component is used in high-voltage commercial equipment. Installation and electrical troubleshooting should be performed by a qualified technician familiar with LiftMaster commercial operator systems.

After replacement, verify proper operator function, travel limits, control stations, safety devices, and entrapment-protection systems before returning the equipment to service.
