Description
The Rheem-Ruud 45-25323-02 is an OEM replacement flame sensor wire designed to restore proper flame detection performance in compatible Rheem and Ruud heating systems. Flame sensor wires are a critical component in gas furnace safety circuits — they carry the signal from the flame sensor rod to the control board, confirming that ignition has occurred and allowing the gas valve to remain open. A damaged, corroded, or broken flame sensor wire can cause nuisance lockouts, no-heat calls, and intermittent ignition failures.
Key Features
- OEM replacement part manufactured to Rheem-Ruud specifications
- Designed for direct, drop-in replacement in compatible Rheem and Ruud furnace models
- Maintains reliable signal transmission between the flame sensor and control board
- Helps prevent nuisance lockouts caused by a faulty or degraded sensor wire
- Supports proper furnace safety circuit operation
Application
- Compatible with select Rheem and Ruud gas furnace models — verify compatibility using your unit’s model and serial number before ordering
- Ideal for use during routine furnace maintenance, tune-ups, or no-heat service calls
Why Replace Your Flame Sensor Wire?
Over time, flame sensor wires can become brittle, cracked, or develop poor connections due to heat cycling and age. Replacing the wire with a genuine OEM part ensures the flame sensing circuit operates as the manufacturer intended, reducing callbacks and ensuring long-term system reliability.
