Electrolux Range Error Code LEDs 1,2

The LEDs 1 and 2 error code on an Electrolux range indicates a runaway temperature condition, meaning the oven has exceeded its safe upper temperature threshold. This is a protective fault triggered by the electronic control board when it detects that the oven cavity temperature has climbed beyond the acceptable operating range. The control board continuously monitors temperature data from the oven temperature probe (also called an RTD sensor) and uses that data to regulate the bake and broil elements. When incoming probe data suggests an out-of-range temperature, the board flags the runaway condition and activates the LED fault indicators.

The oven temperature probe is the first component to evaluate. At room temperature, a properly functioning probe should read between 1050 and 1100 ohms of resistance. A probe that reads significantly outside this range, whether too low due to a short or too high due to an open circuit, will send incorrect temperature data to the control board. If the board receives a signal suggesting the oven is hotter than it actually is, or if the probe is sending erratic readings, it may interpret the condition as a temperature runaway and lock out normal operation.

If the probe resistance tests within the 1050 to 1100 ohm specification, the fault lies with the electronic control board itself. The control board is responsible for interpreting probe data and managing power to the heating elements. A board with failed components can misread accurate probe signals, fail to cycle the elements off at the correct temperature, or incorrectly trigger the runaway fault. In either scenario, continued operation without repair is a fire and safety risk.
