Carrier L99H008 Heater Element

The Carrier L99H008 is a high-performance 5KW Heater Element designed for precise thermal regulation in compatible air handling units and heat pump systems. This open-coil nichrome heating element is engineered to meet OEM specifications, ensuring seamless integration with existing terminal blocks and safety limit switches. As a direct replacement for Carrier heater kits, the L99H008 provides the necessary BTU output for auxiliary or emergency heat applications. The heavy-duty ceramic insulators provide superior dielectric strength, while the reinforced frame maintains coil integrity under high-static pressure conditions. Integrating this HVAC electric heater element maintains system airflow velocity and ensures accurate cycling rates to prevent nuisance tripping of the primary limit. Field technicians will find the mounting hole patterns and wire leads facilitate a clean installation in Carrier residential air handlers. Proper kilowatt rating matching is critical for secondary heat performance during low-ambient operation.

• Precision Wound Coil: Features high-grade nichrome resistive wire for consistent heat distribution and longevity.
• OEM Compatibility: Exact dimensional match for Carrier L99H008, reducing field modification time.
• Thermal Safety: Compatible with standard auto-reset thermal limits to protect the heat exchanger from overheating.
• Durable Construction: Corrosion-resistant plated steel frame specifically built for commercial and residential HVAC environments.

What is the typical voltage rating for this 5KW element?
The L99H008 is rated for 208/240V single-phase applications, delivering approximately 17,060 BTUs at the full 240V rating.

Can this element be used in downflow configurations?
Yes, provided the air handler unit is certified for multi-poise installation and the minimum CFM requirements are met to dissipate the 5KW load.

How do I verify if this heating element has failed?
Perform a continuity test across the terminals using a multimeter; an infinite resistance reading indicates an open circuit and the need for replacement.
