What Does Code LED Steady On Mean?

A steady green status LED on the Ruud UGPH-07EAMGR control board means the UTEC 1012-925 Integrated Furnace Control is receiving power and operating without any fault conditions. The microprocessor has completed its diagnostic checks and found no issues. The furnace is either actively heating your home or standing by, waiting for a thermostat call.

If your furnace is not producing heat despite showing this normal status, the issue lies outside the control board. Verify that your thermostat is set to "Heat" mode and the set temperature is higher than the current room temperature. Check that the thermostat batteries are fresh and that the wiring between the thermostat and furnace is secure.

This LED state requires no service action. It is the expected indication when the furnace is functioning properly.

Contact a licensed HVAC technician if any of these apply:
