Nordyne 904166 Relay Kit

Ensure reliable sequence control and electrical distribution within your HVAC system with the Nordyne 904166 Relay Kit. This genuine OEM Nordyne part is engineered for seamless integration into FEHA-series and related electric furnace configurations, often serving as a critical component when upgrading units with air conditioning or heat pump systems. By facilitating precise blower speed selection and managing high-voltage transitions, this kit eliminates the common issue of erratic fan cycles and relay chattering often seen with substandard aftermarket alternates.

Constructed for professional-grade durability, the 904166 relay assembly features robust switching points designed to handle the inductive loads of high-static blower motors. Field technicians will appreciate the simplified low-voltage terminal board connections, which expedite the wiring of thermostats and outdoor condensing units. Whether you are performing a furnace relay replacement or a new system integration, this lead-wire-equipped kit provides the exact electrical specifications required to maintain system listing and operational safety without the need for improvised mounting.

Key Benefits for Contractors:

• OEM Compatibility: Specifically designed for Nordyne, Intertherm, and Miller electric furnaces, ensuring a perfect mechanical and electrical fit.
• Enhanced Control: Provides reliable switching for multi-speed blowers, optimizing airflow for both heating and cooling cycles.
• Simplified Installation: Includes pre-configured wiring and terminal points to reduce field labor time and potential wiring errors.
• Durable Construction: Built to withstand the thermal cycling and high-frequency operation typical in residential HVACR environments.

Common Questions:

What are the wiring positions for heating and cooling?
Standard field practice typically involves setting the orange wire on terminal 2 for heating and the violet wire on terminal 4 for cooling, though you should always verify the specific blower speeds against the furnace nameplate data.

Is this kit required when adding a central A/C unit?
Yes, the Nordyne 904166 is often the designated relay kit required to provide the necessary 24V-to-240V switching logic for air conditioning integration in older electric furnace models.

Can this relay handle high-static blower motors?
This kit is rated for the standard motors found in Nordyne residential equipment, providing the necessary ampacity for reliable start-up and continuous operation.
