Trane SFRLY90290 Fan Relay

The Trane SFRLY90290 serves as a reliable 24V switching relay for residential and light commercial HVAC applications, specifically designed to manage high-amperage indoor blower motors. As a heavy-duty SPNO (Single Pole Normally Open) fan relay, it provides a dedicated 14A contact rating to ensure stable electrical connections under constant load. This component is the primary OEM replacement for RLY2764, offering a direct terminal-to-terminal match that eliminates the need for specialized field modifications during a service call.

Built with high-grade silver cadmium oxide alloy contacts and a compact, multi-positional frame, the SFRLY90290 excels in tight control cabinets where 1/4-inch quick connect terminals facilitate efficient wiring. Optimized for 50/60 Hz systems, this relay features Class B insulation and is rated for operational temperatures from -40°F to 149°F. Integrating this Trane replacement relay ensures high-performance fan sequencing and consistent motor control, making it a critical stock item for technicians performing HVAC blower motor repairs or 24V control circuit troubleshooting.

• Direct Manufacturer Replacement: Engineered to replace RLY2764 with identical footprint and electrical capacity.
• High Current Handling: Rated for up to 14A inductive loads, ideal for switching high-static blower motors.
• Versatile Mounting: The multi-positional design allows for standard screw-down mounting in various furnace and air handler enclosures.
• Standard 24V Logic: Compatible with most HVAC control boards and 24VAC thermostat circuits.

• What does SPNO mean for this application? This is a Single Pole Normally Open relay, meaning the circuit stays open until the 24V coil is energized by the thermostat or control board, at which point the 14A contacts close to power the fan.
• Can I use this for non-Trane equipment? While designed as a Trane OEM part, it can be used in any system requiring a 24V coil relay with a 14A/120V or 240V contact rating, provided the mounting dimensions align.
• Is this relay suitable for 50Hz systems? Yes, the SFRLY90290 is rated for both 50Hz and 60Hz frequencies, supporting domestic and international power standards.
