When you're out in the field and the heat pump can’t keep up with the winter design temperature, the Carrier 320074-702 5KW Heat Strip is the standard solution for supplemental or emergency electric heat. As a high-performance electric heater kit, this 5kW resistance element integrates directly into compatible air handlers to provide an additional 17,000+ BTU/hr of heating capacity. Engineered for 208/240V single-phase electrical systems, it draws approximately 20.8 Amps at 240V, making it a reliable choice for common residential and light commercial HVAC replacement parts. The Carrier heating element features a durable, corrosion-resistant construction designed for high-airflow environments, ensuring it can withstand the thermal cycling typical of ducted forced-air systems. Whether you are performing a Carrier 320074-702 installation to fix a failing auxiliary heat circuit or upgrading a system for better cold-weather performance, this OEM component ensures factory-spec compatibility and reliable thermal protection through its integrated high-limit safety switches.

• Precise 5kW Output: Provides consistent supplemental heating to assist heat pumps during defrost cycles or extreme outdoor temperatures.
• OEM Integration: Specifically designed to fit the internal mounting rails of compatible air handling units for a secure, rattle-free installation.
• Dual-Voltage Versatility: Fully operational on both 208V and 240V 50/60 Hz power supplies, catering to various site-specific electrical requirements.
• Enhanced Durability: Constructed with heavy-duty galvanized steel and premium resistance wire to maximize service life in high-demand environments.

Is the Carrier 320074-702 compatible with all air handlers?
No, while this 5kW electric heating kit fits many common units, you must verify the cabinet size and mounting configuration of your specific air handler model to ensure a proper fit.

Does this heater kit include the circuit breaker?
This model is the heating element assembly. Always check your specific unit’s parts list to determine if an additional single-point power box or specific breaker kit is required for your installation.

What is the primary cause of heat strip failure?
The most common issues are restricted airflow due to dirty filters or undersized ductwork, which causes the thermal limit switches to trip frequently, eventually leading to element burnout.
