Rheem RGPH-07EAMGR Error Code LED Steady On: Normal Operation
What Does Code LED Steady On Mean?
A steady (non-blinking) OK LED on the Rheem RGPH-07EAMGR means the microprocessor and control board are powered up and operating normally. No fault conditions are detected by the system.
The UTEC 1012-925 Integrated Furnace Control uses the OK LED to communicate system status. When the LED is on solid without any blinking patterns, it confirms that the board has power, the microprocessor is running its program correctly, and no safety switches or sensors are reporting problems.
If your furnace is not heating despite showing a steady OK LED, the issue is likely outside the control board — check your thermostat settings (make sure it is set to HEAT and the temperature is set above the current room temperature), verify the gas supply valve is turned on, and make sure the furnace access panel is fully closed to engage the door safety switch.
