Rheem RGPH-07EAMGR Error Code LED Steady On: Normal Operation
What Does Code LED Steady On Mean?
The UTEC 1012-925 IFC lights its "OK" status LED steadily whenever the microprocessor is powered and has detected no external fault. On the RGPH-07EAMGR this steady glow is the healthy baseline — the board is watching the pressure switch, limit switch, and flame-sense circuit and finding everything in range.
Because this board reports faults by blinking (one to four blinks with a 2-second pause) rather than by a steady light, a solid LED is simply the absence of those fault patterns. A separate amber flame-sense LED indicates flame current during a heat cycle: steady means good flame current, while a flash warns the current is marginal. During normal firing you may see the "OK" LED solid and the amber LED solid together.
If the furnace is not heating even though the "OK" LED is steady, the control board itself is fine — look instead at the thermostat (setting, batteries, wiring) or a call-for-heat that is not reaching the board. A steady LED rules the control out as the problem.
What You'll Notice
- The "OK" status LED glows steadily with no blinking pattern.
- The furnace runs normally on a call for heat, or sits quietly in standby with the LED lit.
Common Causes

How This Is Diagnosed
No diagnosis is required — a steady "OK" LED is the normal, no-fault indication. To confirm the furnace is otherwise healthy, verify that a call for heat produces the normal sequence (inducer, igniter, burners, then blower) and that warm air reaches the registers. If it does not heat despite the steady LED, check the thermostat rather than the control board.
- The status LED is steady but the furnace never starts a heating cycle on a call for heat, pointing to a thermostat or wiring issue rather than the board
- The LED changes from steady to a blinking pattern, which identifies a specific fault to look up
Frequently Asked Questions
Is a steady LED on my Rheem furnace good or bad?
It is good. A steady "OK" LED means the control board is powered and has found no faults. Faults are shown by blinking, not by a steady light.
The LED is steady but I have no heat — what now?
The control board is fine, so check the thermostat first: confirm it is set to heat, the batteries are good, and the temperature is set above room temperature. If the thermostat is fine and there is still no heat, have a technician trace the call-for-heat signal.
What is the amber LED next to the "OK" light?
That is the flame-sense indicator. Steady means the flame current is good during a heat cycle; a flashing amber LED warns of a marginal flame signal that may need the flame sensor cleaned.
