White Rodgers 124-114111 Solenoid
The White Rodgers 124-114111 is a 24 VDC solenoid built for HVAC control systems requiring reliable switching. Its SPNO configuration and isolated coil suit contractors and maintenance technicians who need a dependable continuous-duty contactor for heating or cooling equipment.
100 Amp continuous rating with 400 Amp inrush
The contact rating of 100 Amps handles sustained loads in compressor or fan circuits, while the 400 Amp inrush capacity absorbs motor starting surges. A coil resistance of 53 ohms defines the control current draw, and the unit operates from -40 to +149 degrees F in water-resistant and dust-resistant conditions.
Replaces failed contactors in existing 24 VDC HVAC
This solenoid serves as a direct replacement when an original contactor fails or shows pitted contacts, restoring switching function without rewiring. The upgrade is worthwhile when the existing coil voltage matches 24 VDC and the application demands continuous duty with high inrush tolerance.

Questions about this item
Will this 24 VDC solenoid work with my existing 24 V control board?
Yes, it operates on 24 VDC with a 53 ohm coil, so it draws the expected current from a standard 24 V control circuit.
How can I confirm the 124-114111 is functioning after installation?
Apply 24 VDC to the coil terminals; you should hear a firm click and measure continuity across the power contacts, indicating the 100 A continuous circuit is closed.
Does the 124-114111 package include mounting brackets or wiring connectors?
The solenoid is supplied as the standalone unit; mounting hardware and wire terminals are not included and must be sourced separately.
