Electrolux Dryer Error Code E24
Control thermistor or its wiring is shorted (Control NTC Short Circuit).
Control thermistor or its wiring is shorted (Control NTC Short Circuit).
First step from the service manual
Remove wires from control thermistor. Measure resistance of thermistor. If reading is not 50K (±10%), replace thermistor. If reading is within 50K (±10%), check wiring between thermistor and electronic control. If good, replace electronic control.

What E24 means on a Electrolux dryer
The E24 error code on an Electrolux dryer indicates a short circuit condition in the control thermistor (also called the control NTC, or Negative Temperature Coefficient sensor) or in the wiring that connects it to the electronic control board. The control thermistor is a resistive temperature sensor that monitors temperature at a specific point in the dryer's control system. Under normal operating conditions, the thermistor should measure approximately 50K ohms of resistance. A short circuit causes the resistance to drop far below this expected value, signaling to the control board that a fault exists.
This fault typically originates from one of two sources: a failed thermistor or a wiring problem between the thermistor and the control board. Thermistors can fail internally due to heat exposure, age, or manufacturing defects, causing them to short internally and report artificially low resistance. Wiring faults such as pinched wires, damaged insulation, or corroded connectors can also create a low-resistance path that the control board reads as a short circuit condition.
Diagnosing E24 requires disconnecting the thermistor's wiring and measuring its resistance with a multimeter. A reading within 10 percent of 50K ohms confirms the thermistor itself is functioning correctly, which shifts the investigation to the wiring harness and connectors between the thermistor and the control board. If both the thermistor and wiring check out, the electronic control board may be misreading the signal and will need to be replaced.

Common causes of E24
- 01
Failed control thermistor
Part replacementThe thermistor has internally shorted, causing its resistance to fall well outside the expected 50K ohm range. Disconnect the thermistor wires and measure resistance directly at the sensor terminals to confirm.
- 02
Damaged or shorted wiring harness
Wiring / connectionWires running between the control thermistor and the electronic control board may have pinched, melted, or frayed insulation, creating a short circuit. Inspect the full length of the wiring harness for visible damage, chafing, or contact with hot surfaces.
- 03
Corroded or loose connector
Wiring / connectionMoisture or heat can corrode the connector pins at the thermistor or control board end, causing unintended electrical contact between terminals. Inspect both connectors for corrosion, bent pins, or poor seating.
- 04
Faulty electronic control board
Part replacementIf the thermistor measures within 10 percent of 50K ohms and the wiring is undamaged, the control board itself may be misinterpreting the thermistor signal. Replacing the control board is the next step after ruling out the sensor and wiring.
