Carrier HN61KP003 Relay

The Carrier HN61KP003 Power Duty Relay is a specialized electrical switching component engineered for high-reliability in residential and commercial HVAC applications. As a direct replacement for the HN61KX010, this OEM Carrier replacement part ensures exact structural and electrical compatibility within your control circuit, eliminating the guesswork associated with "universal" alternatives. Featuring a 208/240V 50/60Hz coil and a robust contact arrangement including SPDT and SPST configurations, this switching relay is designed to manage inductive loads like fan motors and resistive loads such as electric heaters with precision. The unit is rated for 8 FLA / 48 LRA at 240V, providing the high-torque handling required for motor startups while maintaining long-term contact integrity. Whether you are performing a Carrier furnace repair or maintaining a complex air handler, this relay delivers the fast, consistent switching response necessary to protect expensive system components from erratic power cycles.

• Direct Cross-Reference: Engineered specifically as the evolution of the HN61KX010, ensuring zero-modification installation.
• Multi-Voltage Coil: Optimized for 208V/240V operation, making it versatile for diverse power configurations.
• Industrial Build Quality: High-grade contact materials designed to resist pitting and carbon buildup under heavy power duty cycles.
• Precise Control: Supports signals from thermostats and advanced logic boards for efficient heating and cooling transitions.

Is the HN61KP003 compatible with older Carrier units using the HN61KX010?

Yes, the HN61KP003 is the current OEM replacement specifically designated to replace the discontinued HN61KX010 without requiring any wiring harness modifications.

What are the symptoms of a failing power duty relay in an HVAC system?

Common field indicators include a humming noise from the coil, visual pitting on the contacts, or a "stuck" condition where the motor fails to engage or stays energized after the thermostat call terminates. Technicians should verify 240V across the contacts and check coil resistance with a multimeter to confirm failure.

Can I use this relay for both fan motors and electric heat strips?

This HVAC relay is rated for both inductive and resistive loads. It handles up to 12 FLA for 120V applications and is purpose-built for the demands of 240V fan switching and power duty sequences in Carrier-branded equipment.
