Electrolux Dryer Error Code F2

Bake/Broil/Clean Temperature Runaway Alarm

Electrolux codesElectrolux dryer codes

Bake/Broil/Clean Temperature Runaway Alarm: Alarm sounds and resets control to non-cook mode when Bake/Broil/Clean temperature exceeds programmed limits (625°F, 640°F, 900°F respectively).

First step from the service manual

Press the CANCEL key to reset display code and audible for 16 seconds; alarm repeats if fault persists. Temperature must drop below programmed limit and/or power must be removed until serviced.

What F2 means on a Electrolux dryer

The F2 error code on an Electrolux dryer signals a Temperature Runaway condition, meaning the appliance has detected internal temperatures exceeding programmed safety thresholds. Specifically, the control board monitors cavity temperature against fixed upper limits: 625°F for Bake mode, 640°F for Broil mode, and 900°F for Clean mode. When any of these limits is breached, the control system triggers an audible alarm and automatically resets the unit to a non-cook state to prevent damage or a fire hazard. This protective response is built into the control logic and is not a nuisance alarm; it indicates a genuine thermal excursion that must be investigated.

The temperature monitoring system relies on one or more temperature sensors, typically a thermistor or thermostat, to relay real-time cavity readings back to the control board. If a sensor is malfunctioning and sending incorrect high-temperature readings, the board may trigger F2 even when actual temperatures are within safe ranges. Conversely, a faulty heating element, a stuck relay on the control board, or a failed safety thermostat can allow actual temperatures to rise unchecked until the runaway threshold is reached.

Resetting the error requires pressing the CANCEL key, which clears the display and silences the alarm for 16 seconds. However, if the underlying fault persists, the alarm will repeat. The temperature must drop below the applicable programmed limit before normal operation can resume, and in some cases the unit must be fully de-energized until the root cause is identified and corrected. Simply resetting without diagnosis is not a permanent solution.

Common causes of F2

  1. 01

    Faulty Temperature Sensor or Thermistor

    Part replacement

    A failing thermistor can send inaccurate high-temperature readings to the control board, triggering the F2 alarm even when actual cavity temperatures are normal. Resistance values outside the expected range for the sensor confirm this diagnosis.

  2. 02

    Stuck or Shorted Heating Element Relay

    Part replacement

    If the relay on the control board that governs the heating element sticks in the closed position, the element runs continuously without cycling off, causing temperatures to climb past the programmed limits. This requires inspection of the control board relay contacts.

  3. 03

    Failed Safety Thermostat

    Part replacement

    The high-limit safety thermostat is designed to cut power to the heating circuit if temperatures exceed safe levels. A thermostat that has failed in the open or closed position can either cause runaway heating or prevent the system from self-correcting.

  4. 04

    Defective Control Board

    Part replacement

    The control board manages all temperature thresholds and heating cycles. If the board itself is malfunctioning, it may misread sensor inputs or fail to cut power to the heating element at the appropriate time, resulting in a temperature runaway condition.

  5. 05

    Restricted Airflow or Clogged Exhaust

    Wiring / connection

    Blocked venting or a severely clogged lint trap can trap heat inside the drum, causing temperatures to rise beyond normal operating ranges. Inspect and clear the exhaust duct and lint filter as part of initial diagnostics.

Frequently asked questions about F2

What does F2 mean on a Electrolux dryer?
The F2 code on an Electrolux dryer indicates a Temperature Runaway Alarm. The control system has detected that the internal temperature exceeded the programmed safety limit for the active mode: 625°F for Bake, 640°F for Broil, or 900°F for Clean. When this occurs, the control resets to a non-cook state and sounds an alarm to prevent damage or fire.
Will pressing Cancel fix the F2 error on my Electrolux dryer?
Pressing the CANCEL key will clear the display code and silence the audible alarm for 16 seconds, but it does not fix the underlying problem. If the fault condition persists, the alarm will repeat. The temperature must drop below the applicable limit and the root cause must be corrected before the dryer will operate normally again.
Is it safe to use my Electrolux dryer while the F2 code is active?
No, you should not continue using the dryer while an F2 code is present. The error indicates a potentially dangerous overheating condition, and the control system has already shut the appliance down as a safety measure. Continued use before the cause is diagnosed and repaired could result in damage to components or a fire risk.
What does it cost to repair an F2 temperature runaway error on an Electrolux dryer?
Repair costs vary depending on the faulty component. Replacing a thermistor or thermostat typically falls in a lower cost range, while a control board replacement is considerably more expensive. Including labor, total repair costs can range from around $100 to $400 or more depending on the part required and local service rates.
Can I diagnose the F2 error myself on an Electrolux dryer?
Knowledgeable DIYers can begin by checking for restricted airflow and clearing the exhaust duct and lint filter, which requires no special tools. Testing the thermistor or thermostat for correct resistance values and inspecting the heating element circuit requires a multimeter and comfort working with appliance wiring. Control board diagnosis and replacement is generally best left to a qualified technician.
