White-Rodgers 90-293Q Relay

The White-Rodgers 90-293Q is a heavy-duty SPDT 24V fan relay engineered for reliable switching in high-demand HVACR applications. As a Type 84 magnetic relay, it is the professional-grade solution for managing single or two-speed fan motors, solenoids, and resistive loads. This unit features a totally enclosed design to ensure quiet operation and protection against environmental contaminants, making it a staple for both heating and cooling system service. With its universal mounting bracket and standard 1/4-inch quick-connect terminals, it allows for seamless installation in tight control cabinets.

Technicians frequently utilize the 90-293Q relay as a direct replacement for 024-18006-700, 90-293, and 90-296Q models. It operates with a 24 VAC coil featuring 90 Ohms DC resistance and a 125 mA nominal current draw. The inductive contact rating handles up to 8 Amps at 125/250 VAC, while the resistive load capacity is rated at 16 Amps. Built for long-term field durability, this switching fan relay is rated for 100,000 electrical cycles, ensuring stable performance in residential and light commercial air handlers or furnace systems.

• Broad Compatibility: Serves as a universal HVAC fan relay replacing multiple legacy White-Rodgers and OEM part numbers.
• Quiet Operation: The enclosed coil design minimizes mechanical hum, essential for residential indoor air handlers.
• Durability: High-quality silver cadmium oxide contacts provide superior arcing resistance and extended cycle life.
• Easy Retrofitting: Compact footprint and universal mounting simplify the replacement of bulkier older-style relays.
• Technical Precision: Maintains SPDT (Single Pole Double Throw) switching logic for flexible normally open or normally closed wiring configurations.

Is the 90-293Q compatible with 208/240V fan motors?
Yes, while the coil requires a 24V control signal, the contacts are rated to switch loads up to 250 VAC, making it suitable for most 120V and 240V fan applications.

Can I use this relay to replace a 90-293 or 90-296Q?
Absolutely. The 90-293Q is the designated direct replacement and provides the same electrical specs and mounting footprint as those discontinued or alternate models.

What is the purpose of the 'Q' suffix in the part number?
The 'Q' typically designates the quick-connect terminal configuration, allowing for faster wiring without the need for specialized tools.
