The Amana-Goodman HKR-03 is a 3kW electric heat strip engineered for field installation in compatible air handlers and modular blowers. Designed to provide supplemental or emergency heating, this downflow and horizontal discharge heater kit features a nichrome heating element for consistent thermal transfer and durability. This 230V single-phase heater integrates seamlessly into the air handler cabinet, utilizing a plug-in wiring harness to reduce installation time and ensure secure electrical connections. Technicians should note the built-in overcurrent protection and thermal limit switches that prevent overheating. This auxiliary heat kit is essential for heat pump systems requiring a defrost cycle supplement or primary heat in smaller residential applications. Ensure your breaker size and wire gauge meet the 15.6 minimum circuit ampacity requirements. The HKR-03 heat kit is compatible with various Amana, Goodman, and Direct Comfort units, providing a reliable 10,236 BTU output for precise climate control. Key Benefits Direct Integration: Features a factory-tested plug-in wiring harness for simplified field installation. Thermal Safety: Equipped with primary and secondary thermal limit protection to prevent sequential overheating. Corrosion Resistance: Utilizes rust-resistant nickel-chromium heating coils for extended operational life in high-airflow environments. Versatile Mounting: Qualified for multiple positions, including upflow, downflow, and horizontal configurations. Common Questions What is the maximum CFM required for the HKR-03? Standard installations require a minimum airflow threshold—typically around 500-600 CFM—to ensure the thermal sequencers do not trip during operation. Can this be used as the sole heat source? While the 3kW output provides approximately 10,230 BTUs, it is frequently used as emergency heat or for supplementary heating in smaller zones or warmer climates. Is a separate circuit breaker included? The HKR-03 provides high-voltage terminal blocks; however, technicians must verify if the specific air handler model requires an additional pull-out disconnect or external breaker based on local NEC codes.
