Customer Questions and Answers for Control Board (Printed Circuit Board) by Frigidaire

This control board is the appliance's primary printed circuit board. It governs cycle timing, options, and power to key components. Replacing a failed PCB can restore responsive controls and consistent operation across all cycles.

• Coordinates inputs from sensors/controls and directs outputs to motors, valves, pumps, and other loads
• Manages cycle sequencing and option selections as designed by the manufacturer
• Symptoms of a failing board can include no start/no response, cycles that won't advance or end early, intermittent/erratic operation, blank or flickering indicators, or recurring error codes

• Disconnect power before servicing; do not work on a live appliance
• Use ESD protection and handle the board by the edges to avoid damage
• Photograph existing wiring; move connectors one at a time to the matching positions on the new board
• Secure the board and any covers before restoring power; run a test cycle/diagnostic per your model's service information
