What F6 means on a Electrolux dryer

The F6 error code on an Electrolux dryer indicates that the control board's AC line cycle detector is not receiving the expected AC line cycle signal. The control monitors the incoming AC power supply for its standard 60 Hz cycling pattern. When this cycling signal is absent for a continuous sample period of one minute, the board registers the F6 fault, displays the code visually without triggering an audible alarm, and automatically resets the control into a non-cook (non-heat) mode as a protective measure.

The AC line cycle detector circuit is an internal function of the control board, but it depends entirely on a stable and properly configured AC power input at the dryer's supply. If the dryer is receiving incomplete power, such as a lost leg on a 240-volt circuit, or if the supply voltage is severely degraded, the control board will fail to detect the normal AC line cycles. Wiring faults at the terminal block, a tripped breaker, or a failed outlet can all prevent the correct AC signal from reaching the board.

Because the code triggers a reset to non-cook mode, the dryer may still appear to power on but will not produce heat. Diagnosis should begin at the AC power supply, confirming that both legs of the 240-volt circuit are present and delivering correct voltage. If supply power is confirmed good, attention shifts to the internal wiring between the terminal block and the control board, and ultimately to the control board itself if no other fault is found.

Common causes of F6

  1. 01

    Lost leg on 240-volt circuit

    Wiring / connection

    Electrolux dryers require a 240-volt supply with two hot legs. If one leg is lost due to a partially tripped breaker or a failed utility connection, the AC line cycle signal can disappear. Check both legs at the outlet with a multimeter for approximately 120 volts each to ground.

  2. 02

    Tripped or faulty circuit breaker

    Wiring / connection

    A breaker that has tripped partially may still show as ON visually but not be delivering full power. Reset the breaker fully by switching it to OFF and then back to ON, and verify voltage at the outlet afterward.

  3. 03

    Faulty power outlet or wall receptacle

    Part replacement

    A worn or damaged 240-volt dryer receptacle can cause intermittent or complete loss of one or both power legs. Inspect the outlet for burn marks, corrosion, or loose connections, and test voltage directly at the receptacle terminals.

  4. 04

    Loose or damaged wiring at the terminal block

    Part replacement

    The terminal block where the dryer's power cord connects internally can develop loose or burned connections that interrupt the AC supply before it reaches the control board. Inspect the terminal block for discoloration, melted insulation, or loose screws.

  5. 05

    Failed control board

    Part replacement

    If AC power supply and all internal wiring are confirmed good, the control board's AC line cycle detector circuit itself may have failed. A faulty board will need to be replaced to resolve the F6 fault.

Frequently asked questions about F6

What does F6 mean on a Electrolux dryer?
The F6 code means the dryer's control board is not detecting AC line cycles from the incoming power supply. When this signal is missing for a full minute, the board displays the code and disables the heating function as a protective reset. The fault points to a problem with the AC power supply, the circuit wiring, or in some cases the control board itself. No audible alarm accompanies this code.
Can I fix the F6 error code myself?
Some causes of F6 are accessible to a knowledgeable DIYer. Checking and resetting the circuit breaker, testing outlet voltage with a multimeter, and inspecting the terminal block for loose connections are reasonable first steps. However, if the fault involves replacing the wall receptacle or the control board, comfort with electrical work and proper safety precautions are essential. When in doubt, contact a qualified appliance technician.
Is it safe to use my Electrolux dryer when F6 is displayed?
The dryer resets to non-cook mode when F6 triggers, meaning it will not produce heat. The underlying cause, a missing or degraded AC supply leg, is an electrical issue that should be diagnosed and corrected before continuing to use the appliance. Operating the dryer with a compromised power supply risks damage to the control board and other components.
Will resetting the dryer clear the F6 code?
A reset may temporarily clear the code, but if the root cause is not corrected, F6 will return after the control samples the AC line cycles for another one-minute period. The fault must be resolved at the source, whether that is restoring proper power at the breaker, outlet, or internal wiring, for the code to stay cleared.
How much does it cost to repair an F6 error on an Electrolux dryer?
Repair costs depend on the cause. Resetting a tripped breaker costs nothing. Replacing a 240-volt wall receptacle typically runs in the range of $75 to $150 for parts and labor. A new control board, if that is the required fix, can range from $150 to $350 or more depending on the specific model and labor rates in your area.
