Ensure your customer's electric furnace or air handler returns to peak thermal output with the Carrier 330064-703 Element Assembly. This OEM Factory Authorized Part is a critical 5kW electric heating element designed specifically for 240V HVAC systems. Engineered for a precise fit in specific Carrier, Bryant, and Payne air handlers—including the FB4 series models like the FB4BNL and FB4CNF—this resistive heating element converts electrical energy into forced-air heat with high efficiency. For technicians troubleshooting a failed heater bank or a "no heat" call, this 12-inch open coil element provides a direct, drop-in replacement that eliminates the clearance and sequencing issues common with generic aftermarket kits. Its robust construction minimizes mechanical fatigue during thermal expansion cycles, ensuring the HVAC heating assembly maintains consistent amperage draw and BTU delivery throughout the heating season.

Common Questions

Is the 330064-703 compatible with 208V systems?
Yes, but note that operating at 208V will result in a lower watt density and reduced BTU output compared to the 240V rating.

What causes this element assembly to fail?
Frequent failures are typically caused by restricted airflow, often from dirty filters or undersized ducting, which leads to high-limit tripping and eventual element burnout.

Can I use this in an air handler from another brand?
This is a Factory Authorized Part specifically dimensioned for Carrier-made cabinets. Using it in non-compatible brands may cause safety hazards or improper heating.
