Rheem RGPH-07EAMGR Error Code Flame LED Rapid Blink: Unexpected Flame Detected
What Does Code Flame LED Rapid Blink Mean?
A rapidly blinking amber flame sense LED on the Rheem RGPH-07EAMGR indicates that the control board is detecting a flame signal when there should be no flame present. This is a serious safety concern because it suggests gas may be flowing to the burners when the gas valve should be closed.
The most likely cause is a gas valve that is stuck open or leaking, allowing gas to flow when the valve is de-energized. The control board detects the unexpected flame through the flame sensor and responds by running the inducer motor to vent any combustion products. However, the root cause — uncontrolled gas flow — requires immediate attention.
In some cases, a short circuit in the flame sensing wiring or a defective flame sensor giving false readings can also trigger this condition without an actual flame being present. However, because the consequences of a real gas leak are severe, you should treat this as a genuine emergency until a technician can verify otherwise. Turn off the gas supply valve immediately and do not attempt to operate the furnace.
Common Causes
When to Call a Professional
Contact a licensed HVAC technician if:
- This requires immediate professional attention — turn off the gas supply right away
- You smell gas near the furnace at any time
- The inducer motor is running continuously without a normal heating cycle
