Nordyne 902820 Heat Strip

The Nordyne 902820 is a 5kW electric heat strip designed for field installation in Nordyne, Broan, Intertherm, and Miller electric furnaces and air handler units. This auxiliary heating element provides 17,000 BTUs of supplemental heat, serving as a reliable backup or primary heat source for E2, E3, and FE Series cabinets. The assembly features high-grade nichrome heating coils and integrated limit switches for thermal protection, ensuring the unit cuts power if airflow is restricted. Contractors should note that this 5 kilowatt heater kit utilizes a 4-pin plug-in connector for quick integration with the existing control board and wiring harness, eliminating the need for complex field modifications. Proper static pressure and CFM delivery must be verified to ensure optimal heat dissipation across the elements and to prevent premature cycling of the thermal limiters.

Key Technical Benefits:

• OEM Compatibility: Exact drop-in replacement for Nordyne 902820 and 05KW-01 heater kits.
• Integrated Safety: Features primary and secondary auto-reset thermal limits to protect the heat exchanger and blower motor.
• Simple Installation: Utilizes a specialized wiring harness and mounting plate compatible with standard HVAC air handlers.
• Reliable Heat Transfer: Open-coil design allows for maximum airflow contact and rapid thermal response during a defrost cycle or heating demand.

Common Contractor Questions:

Does this 5kW heat strip require a dedicated circuit breaker?
Yes, typical HVAC installation standards require a 30-amp breaker for a 5kW load, depending on local electrical codes and the specific furnace nameplate data.

Is the 902820 compatible with E3EB series furnaces?
Yes, this Nordyne heater kit is the standard 5kW option for E3EB electric furnaces, provided the cabinet size supports the 5kW configuration.

What causes these heating elements to fail prematurely?
The most common causes are restricted air filters or undersized ductwork, which lead to high static pressure and cause the limit switches to cycle frequently, eventually burning out the nichrome coils.
