White-Rodgers 90-294Q Relay

The White-Rodgers 90-294Q Relay is a heavy-duty, Type 84 enclosed fan relay engineered for versatile switching in multi-speed blower systems, resistive loads, and general-purpose HVACR applications. This SPDT 120V relay features a 115/120 VAC coil with a 2000 Ohm DC resistance, drawing a nominal 25 mA for high-efficiency operation. Designed for rigorous field use, the unit provides a compact, fully enclosed housing that protects internal switching contacts from dust and debris, ensuring reliable performance in both heating and cooling sequences. With a contact rating capable of handling 8 Amps continuous inductive load and up to 25 Amps resistive at 240V, it is a primary choice for contractors replacing worn-out furnace blower relays or upgrading controls for compatibility with modern 120V pilot duty circuits. The 1/4-inch quick-connect terminals simplify integration into existing wiring harnesses, providing clear termination points for normally open (NO) and normally closed (NC) configurations.

• Universal Compatibility: Replaces common 120V SPDT fan relays including Mars 90294, Jard 92294, and Packard PR294Q.
• Quiet Operation: Precision-wound coil and mechanical linkage reduce "relay chatter" in residential and commercial air handlers.
• Technical Reliability: Rated for a mechanical life of 1,000,000 operations, making it a dependable component for high-cycle applications.
• Compact Footprint: Enclosed design allows for mounting in tight control panels and junction boxes without exposure risks.

What is the difference between the 90-294Q and 90-293Q models?
The technical distinction lies in the coil voltage. The 90-294Q is designed for 120V circuits, whereas the 90-293Q is a 24V coil relay. Always verify your control transformer output before installation.

Can this relay control a two-speed fan motor?
Yes, the SPDT (Single Pole Double Throw) action allows you to toggle power between two different fan speed taps or between a humidifier and a blower, depending on your wiring diagram.

Are the terminals compatible with standard HVAC wiring?
The 90-294Q features standard 1/4" male quick-connect terminals, which are the industry standard for most furnace and air handler control boards.
