Customer Questions and Answers for Controller (Electronic Control Board) by Frigidaire

This electronic controller manages an appliance's user interface and core cycle functions so your unit responds to settings and runs programmed cycles. Replacing a faulty controller restores control responsiveness and cycle management. What it does:

• Receives inputs from buttons/knobs and runs the appliance's cycle logic
• Powers and updates the display and indicator lights
• Regulates timing, relays, and other outputs that start motors, heaters, or valves
• Faulty controller symptoms: unresponsive controls, incorrect or stuck cycles, no display or intermittent power, or visible error codes

• Disconnect power to the appliance before beginning any work to avoid shock or damage
• Handle the board by its edges and avoid static discharge; use a grounded wrist strap if available
• After installing, power up and test functions before fully reassembling the appliance
