Bradford White Water Heater Error Code No LED (WR Electronic)

No LED on a Bradford White water heater with a White Rodgers electronic control means the control board is completely off and both the main burner and pilot burner are not operating. The LED indicator relies on thermocouple-generated voltage from a lit pilot flame to illuminate. Without a lit pilot, the control has no power source and displays nothing. This condition can result from an extinguished pilot, a gas supply issue, or a faulty thermocouple.

In most cases, No LED simply means the water heater is not operating rather than indicating an active hazard. However, if you smell gas near the unit, do not attempt to light the pilot. Leave the area, avoid operating any electrical switches, and contact your gas utility immediately. Only attempt relighting procedures when there is no detectable gas odor.

If the fix is simply relighting the pilot, there is no parts cost involved. If the thermocouple has failed, replacement parts typically range from $15 to $40 depending on the model, with professional labor adding $75 to $150 in most markets. A complete White Rodgers gas valve control assembly replacement, if needed, can range from $150 to $350 for parts, plus labor.

Start by following the pilot lighting instructions printed on the label of your water heater to relight the pilot flame. If the pilot lights and stays lit, the control should power up and the LED will illuminate. If the pilot will not light or goes out after you release the control knob, inspect your gas supply and test the thermocouple for proper millivolt output. A thermocouple that reads significantly below the expected range will need to be replaced.

There is no traditional reset procedure for the No LED condition because it reflects a lack of power to the control rather than a latched fault. The correct approach is to light the pilot according to the unit's instructions, which will restore power to the control. If the pilot cannot be sustained, the underlying cause such as a bad thermocouple must be addressed before the control will power up and the LED will illuminate.
