Rheem-Ruud AS-61164-83 Heat Cell

The Rheem-Ruud AS-61164-83 Heat Cell is a precision-engineered OEM secondary heat exchanger replacement designed to restore high-efficiency thermal transfer in compatible gas furnaces. Constructed from heavy-gauge aluminized steel, this 13.13 lb component is built to withstand the corrosive condensate and thermal cycling stresses common in modern residential and commercial HVAC applications. As an identical replacement for AS6116483, it ensures direct fitment, maintaining the factory-specified airflow and combustion pressure required for safe operation. For technicians diagnosing failing condensing furnace heat cells—often indicated by rollout switch trips or visible stress fractures—swapping with this genuine Rheem-Ruud furnace part is the standard for long-term reliability. Its internal channel geometry is optimized for maximum heat extraction, supporting the system's SEER and AFUE ratings. Professional replacement of the aluminized heat exchanger using this factory-grade cell is critical for preventing carbon monoxide leakage and ensuring consistent manifold pressure during peak heating loads.

• Corrosion Resistance: High-grade aluminized steel construction protects the heat cell against the acidic condensate produced during the combustion process.
• OEM Compatibility: This genuine Rheem-Ruud part is the exact replacement for AS-61164-83, eliminating the need for field modifications or bracket adjustments.
• Thermal Efficiency: Maximizes heat transfer from burner gases to the airstream, preserving the system's original fuel efficiency standards.
• Reliable Performance: Engineered to meet strict factory tolerances for expansion and contraction, reducing the risk of premature structural fatigue.

Common Questions

Is the AS-61164-83 compatible with my specific Rheem furnace?
This individual heat cell is used across several Rheem and Ruud furnace platforms. To verify fitment, compare the AS-61164-83 or AS6116483 part number against your unit’s service manual or check for a 13.13 lb aluminized steel specification in the secondary heat exchanger assembly.

Can this heat cell be installed without specialty tools?
Installing a furnace heat exchanger requires a complete disassembly of the burner and blower decks. While standard technician tools are used, precise alignment and new gaskets are often required to maintain a gas-tight seal on the heat cells.

What are the symptoms of a cracked heat exchanger cell?
Common indicators for replacing the aluminized heat exchanger include soot buildup, a strange "formaldehyde" smell, or the furnace burner flame wavering when the blower fan kicks on, which suggests air is pushing through cracks in the cell.
