York S1-3500-405P/A Heater Element

The York S1-3500-405P/A Heater Element is a heavy-duty, field-proven 4.8KW 240V heater element assy designed for precise heat transfer in York, Coleman, and Luxaire electric furnaces and air handlers. Built for the rigors of commercial and residential HVAC maintenance, this OEM replacement heating element ensures the system maintains specified discharge temperatures without overtaxing the sequencer or limit controls. This assembly is engineered specifically for compatibility with EB15A, EB15B, EB17A, and EB17B series units, providing a direct-fit solution that eliminates the need for field modifications during HVAC furnace repair.

For service technicians, the S1-3500-405P/A is the correct resistive heating element choice to resolve "no heat" calls or open element faults in electric furnace assemblies. Operating at 240 volts, it draws approximately 20 amps, requiring proper inspection of the wiring harness and terminal block for signs of thermal stress during installation. Replacing a compromised or grounded element with this 4.8KW HVAC part restores full system capacity and ensures balanced airflow across the coil bank for optimal thermal efficiency.

Key Benefits:

• Direct OEM Compatibility: Verified fit for popular EB and EHA series air handlers, ensuring consistent electrical resistance and mechanical alignment.
• 4.8KW Power Rating: Provides 16,380 BTU/hr of supplemental or primary heat for medium-sized residential and light commercial zones.
• Rugged Build Quality: High-grade resistive wire construction resists oxidation and premature sagging under high-temperature cycles.
• Simplified Installation: Pre-assembled bracket and terminal configuration reduce labor time during heating element replacement.
• Optimized Efficiency: Engineered to match original equipment specifications for airflow resistance, preventing localized hot spots.

Common Questions:

Does this heater element replace the S1-3500-4051?
Yes, the S1-3500-405P/A is the current manufacturer-specified replacement for the legacy S1-3500-4051 and 3500-405P models.

How do I confirm if my furnace requires a 4.8KW or a 5.6KW element?
Check the data plate on the furnace cabinet or the existing element’s stamped rating. Installing a 4.8KW element in a system wired for a larger load will result in insufficient heat output, while the reverse may trip the HVAC circuit breaker.

Are the thermal limit switches included with this assembly?
This specific assembly focuses on the 4.8KW element and bridge. It is best practice to inspect your existing limit switches for continuity and replace them separately if they have been subjected to multiple trip events.
