Frigidaire Dryer Error Code E24

Control NTC short circuit

Frigidaire codesFrigidaire dryer codes

Control NTC short circuit — the control thermistor or its wiring is shorted.

First step from the service manual

Remove wires from control thermistor. Measure resistance of thermistor. If reading is not 50K ohms (±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 Frigidaire dryer

The E24 error code on a Frigidaire dryer indicates a short circuit condition in the control NTC (Negative Temperature Coefficient) thermistor circuit. The control thermistor is a temperature-sensing component that changes its electrical resistance in response to temperature. The electronic control board reads this resistance to monitor temperatures during the drying cycle. When the control detects resistance that is too low (consistent with a shorted circuit), it triggers E24 and typically halts operation to prevent overheating or damage.

The control thermistor should measure approximately 50,000 ohms (50K ohms) at room temperature, with an acceptable tolerance of plus or minus 10%. A shorted thermistor will read significantly below this range, sometimes near zero ohms. A short can occur within the thermistor component itself due to internal failure, or it can result from damaged wiring in the harness connecting the thermistor to the control board, where two conductors make unintended contact.

Diagnosing E24 requires disconnecting the wires from the thermistor and measuring its resistance with a multimeter. If the reading falls outside the 50K ohm range, the thermistor has failed and must be replaced. If the thermistor reads correctly, the wiring harness between the thermistor and the electronic control board should be inspected for pinched, chafed, or melted insulation that could be causing a short. If the wiring checks out, the electronic control board itself may be interpreting the signal incorrectly and would need replacement.

Common causes of E24

  1. 01

    Failed control thermistor

    Part replacement

    The thermistor itself has shorted internally, causing its resistance to fall well outside the required 50K ohm range. This is the most common cause and is confirmed by measuring resistance directly at the thermistor terminals after disconnecting the wiring.

  2. 02

    Shorted wiring harness

    Wiring / connection

    The wiring between the thermistor and the control board has been pinched, chafed, or heat-damaged, causing two conductors to contact each other and create a short. Inspect the full length of the harness for any visible damage or points where wires may be rubbing against the dryer cabinet.

  3. 03

    Loose or corroded thermistor connector

    Wiring / connection

    A connector that has worked loose or developed corrosion can create abnormal resistance readings that the control interprets as a short. Check connector terminals at both the thermistor and the control board for moisture damage, corrosion, or pins that have backed out of the housing.

  4. 04

    Faulty electronic control board

    Part replacement

    If the thermistor measures correctly at 50K ohms and the wiring harness shows no faults, the control board itself may be misreading the thermistor signal due to a failed input circuit on the board. Replacement of the electronic control is the next step in this scenario.

Frequently asked questions about E24

What does E24 mean on a Frigidaire dryer?
E24 on a Frigidaire dryer indicates a short circuit in the control NTC thermistor circuit. The control thermistor is a temperature sensor that should measure approximately 50K ohms of resistance. When the electronic control detects resistance far below that value, it registers a short and displays E24. The fault can originate in the thermistor itself, the wiring harness, or the control board.
Can I fix the E24 error myself?
A knowledgeable DIYer can diagnose E24 with a basic digital multimeter. Start by disconnecting the thermistor wires and measuring resistance at the thermistor terminals. A reading outside the 50K ohm range (plus or minus 10%) means the thermistor needs replacement. If the thermistor reads correctly, inspecting the wiring harness for damage is the next step, but replacing the electronic control board is more involved and may be better handled by a technician.
Is it safe to use my Frigidaire dryer while E24 is displayed?
You should not continue using the dryer while E24 is active. The control thermistor is a critical safety component that helps the dryer monitor temperatures during operation. A shorted or failed thermistor means the control cannot accurately track heat levels, which creates a potential overheating risk. Stop using the dryer until the fault is diagnosed and repaired.
Will resetting the dryer clear the E24 error code?
A power reset may temporarily clear the E24 code, but it will return if the underlying fault is still present. Because E24 points to an active electrical short in the thermistor circuit, the code will reappear as soon as the control reads the abnormal resistance again. A reset is not a fix and does not address the root cause.
How much does it cost to repair an E24 error on a Frigidaire dryer?
Repair costs depend on which component has failed. A replacement control thermistor is generally an inexpensive part, typically in the range of $15 to $40. If the wiring harness requires repair or replacement, costs can vary based on the extent of the damage. Replacing the electronic control board is the most expensive scenario, with parts alone often ranging from $100 to $250 or more, plus labor if a technician is involved.
