Description
The Rheem-Ruud RTG20006UU is an OEM replacement flame rod designed to ensure accurate and dependable flame sensing in Rheem and Ruud heating equipment. Flame rods are a critical safety component in gas-fired heating systems — they detect the presence of a burner flame and signal the control board to confirm ignition, preventing unburned gas from accumulating in the heat exchanger.
Key Features
- OEM Rheem-Ruud replacement flame rod for precise fit and function
- Engineered for accurate flame rectification signal output
- Helps prevent nuisance lockouts caused by weak or degraded flame sensing
- Direct drop-in replacement — no modifications required
- Maintains system safety by confirming burner ignition to the control board
Application
- Compatible with select Rheem and Ruud gas-fired furnaces and heating appliances
- Ideal for service and maintenance replacement of worn or failed flame sensing rods
Why Replace Your Flame Rod?
Over time, flame rods accumulate oxidation and carbon deposits that reduce their ability to pass a microamp signal through the burner flame. A degraded flame rod can cause repeated ignition lockouts, system shutdowns, or no-heat calls. Replacing the flame rod with a genuine Rheem-Ruud part restores proper flame sensing and helps extend the life of the control board and ignition system.
