Carrier HN680067 Heater Relay

The Carrier HN680067 Heater Relay is a specialized OEM component designed for high-reliability switching in residential and commercial HVAC systems. This 24V coil relay features a Double Pole Double Throw (DPDT) configuration, allowing for precise control of multiple circuits or heater elements. As a veteran-grade switching relay, it manages substantial loads with an 18 Amp contact rating, making it a rugged alternative for managing furnace blower motors and electric heat sequences without premature contact pitting.

Engineered as the direct replacement for HN61KQ120, the HN680067 is also compatible with a wide range of legacy part numbers, including HN84HA066 and P283-1203. Its compact White Rodgers design ensures a drop-in fit for existing mounts, operating efficiently at 50/60Hz. When diagnosing a failed HVAC heater relay—typically indicated by "stuck on" blower wheels or heating elements that fail to energize—this genuine Carrier HN680067 provides the exact electrical specifications required to maintain system safety and performance standards.

• Universal Compatibility: Serves as a direct OEM replacement for HN61KQ120, HN61KJ250, and dozens of legacy Carrier/Bryant/Payne part numbers.
• Heavy-Duty Switching: Rated for up to 18 Amps at 120V or 240V, providing robust handling for high-draw heating components.
• Standardized Control Logic: Features a 24V low-voltage coil that integrates seamlessly with standard HVAC control boards and thermostats.
• Versatile Configuration: The DPDT circuit design enables simultaneous switching of two independent power circuits, ideal for complex sequencing.
• Field-Proven Durability: Manufactured by White Rodgers to meet stringent factory specs for cycle life and thermal resistance.

Is the HN680067 compatible with my older HN61KQ120 relay?
Yes, the HN680067 is the direct replacement for HN61KQ120. It maintains the same footprint and terminal locations for a straightforward field replacement.

Why is my blower motor running constantly even when the thermostat is off?
This often indicates a "welded" or stuck contact inside the heater relay. Replacing the old unit with a new Carrier HN680067 restores proper circuit interruption and control.

Does this relay support both 120V and 240V heater circuits?
Yes, the DPDT configuration and 18A rating allow it to switch loads for both 120V and 240V applications, provided the control coil is energized by a 24V signal.
