Introduction
Use this guide to fix an F11 error code on a Frigidaire Gallery stove by cleaning the control module contacts. The control module, also called the control panel or electronic oven control, reads the keypad buttons. Grease, moisture, or grime behind the keypad can cause the stove to beep and show F11. This guide was written using a Frigidaire Gallery stove, so screw types and connector layouts may differ on other Frigidaire models.

Step 2 Remove the rear panel
-
Use a 1/4 inch nut driver and a #6 Robertson screwdriver to remove the six screws from the rear panel.
-
Leave the top middle screw in place until the other screws are out.
-
Lift off the rear panel to expose the back of the control module.
-
-
Step 3 Free the control module
-
Use a Phillips screwdriver to remove the four screws securing the control module.
-
Pull the loosened control module out just enough to reach the wire plugs.
-
-
Step 4 Disconnect the control module wires
-
Release any retaining clips before pulling the connectors off.
-
Unplug every connector, including the grounding wire fourth from the left.
-
Set the control module on a clean, dry work surface.
-
-
Step 5 Peel off the front face
-
Peel the black plastic front face off the control module.
-
Work slowly around sticky areas until the contact surface is exposed.
-
Inspect the exposed contacts for grease, moisture, dirt, or dark spots.
-
-
Step 6 Clean the circuit board contacts
-
Pour a small amount of isopropyl alcohol into a clean small dish.
-
Dip a cotton swab in the alcohol and scrub one exposed contact at a time.
-
Rewet the cotton swab as needed and clean every bit of the contact surface.
-
Switch to a fresh cotton swab when the swab becomes dirty.
-
-
Step 7 Clean the plastic face contacts
-
Use isopropyl alcohol and cotton swabs to clean the matching contact areas on the back of the plastic front face.
-
Clean the spots where the plastic face lines up with the circuit board contacts.
-
Keep cleaning each spot until the contact area looks clean.
-
-
Step 8 Reattach the front face
-
Place the plastic front face back onto the circuit board.
-
Line it up carefully so the buttons sit in the correct places.
-
Press the face down across the surface so it sticks to the board.
-
-
Step 9 Reconnect the wires
-
Push each plug in until it is fully seated.
-
Give each connector a gentle tug to confirm it is snug, but don't pull hard.
-
Slide the ground wire back onto its contact unless the contact is badly corroded.
-
-
Step 10 Reinstall the control module
-
Set the control module back into position and line up the screw holes.
-
Use a Phillips screwdriver to reinstall the four control module screws.
-
Tighten the screws until the module is secure, but don't overtighten them.
-
-
Step 11 Reinstall the rear panel
-
Set the rear panel against the back of the stove and line up the holes.
-
Use the 1/4 inch nut driver and #6 Robertson screwdriver to reinstall the remaining five screws in their original locations.
-
Confirm the rear panel is secure before moving the stove.
-
-
Step 12 Restore power and test
-
Plug the power cord back in.
-
Turn the breaker on.
-
Check the display and listen for the beeping.
-
If the F11 error returns, disconnect power and recheck the cleaned contacts and wire plugs before considering a replacement control module. Repair didn't go as planned? Ask our Answers community for help.
