Introduction
Use this guide to diagnose and repair a Frigidaire dryer that shows the E68 error code. E68 means the control is detecting a stuck button on the control panel. A sticky, damaged, or non-clicking button can keep the control from reading the keypad correctly. Screw locations and button layouts may vary slightly between Frigidaire dryer models.
What you need
-
Step 1 Prepare for E68 diagnosis
-
Confirm that the dryer is showing the E68 error code before opening the control panel.

Step 2 Enter function test mode
-
Turn the timer dial to Normal.
-
Hold Select and Cancel together for six seconds.
-
Immediately hold Start and Cancel together for four seconds.
-
-
Step 3 Run the key button test
-
Rotate the timer knob four clicks to the right to enter the key-button test.
-
Press each control-panel button one at a time.
-
A working button turns on the row of indicator lights.
-
Mark any button that does not light the indicators when pressed.
-
-
Step 4 Remove the top control panel screws
-
Unplug the dryer from the wall.
-
Find the top screw on each side of the control panel that threads into the plastic housing.
-
Remove those two top screws with a screwdriver.
-
-
Step 5 Remove the rear control panel screws
-
Locate the two rear control-panel screws, one on each side behind the panel.
-
Remove the first rear screw.
-
Support the control panel with one hand while removing the second rear screw.
-
Rotate the control panel downward to access the control board.
-
-
Step 6 Remove the control board screws
-
Find the three screws securing the control board to the control-panel assembly.
-
Remove all three screws with a screwdriver.
-
-
Step 7 Release the control board
-
Pull the plastic retaining sides of the control-panel assembly away from the board to release the snap clips.
-
Lift the control board and pull it carefully away from the panel.
-
-
Step 8 Inspect and free the buttons
-
Insert a screwdriver into each button opening to press the switch behind it.
-
Listen and feel for a clear click from each switch.
-
Make sure every switch moves freely and springs back after you press it.
-
Work any sticky switch several times until it clicks and returns normally.
-
-
Step 9 Reassemble the control panel
-
Align the control board with the control-panel assembly.
-
Press the board into place until the snap clips hold it.
-
Reinstall the three control-board screws.
-
Rotate the control panel back into position and hold it steady.
-
Reinstall the two rear screws, then the two top screws that thread into the plastic.
-
-
Step 10 Retest the buttons
-
Enter function test mode again with the timer dial set to Normal.
-
Hold Select and Cancel for six seconds, then immediately hold Start and Cancel for four seconds.
-
Rotate the control knob four clicks to the right to enter the key-button test.
-
Press each button and verify that the row of indicator lights turns on every time.
-
The repair is successful if every button passes and E68 does not return.
-
-
Step 11 Decide if the control board needs replacement
-
Run the key-button test again if E68 returns after reassembly.
-
Work any button that still feels sticky or does not click consistently a few more times.
-
If every button clicks, moves freely, and the same button still fails the test, the electronic control board is likely faulty.
-
Replace the electronic control board if the buttons test good but the E68 code keeps returning.
-
Run the key button test after reassembly and confirm the E68 code doesn't return during normal use. Repair didn't go as planned? Ask our Answers community for help.
