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

This electronic control board is the appliance's main PCB that manages functions and the user interface. Replacing a failed board can restore normal operation when the unit is unresponsive, erratic, or displaying control-related errors.

• Directs operation of key components based on user settings and sensor feedback
• Powers and communicates with the display/interface and control pads
• Coordinates timing through relays and interfaces with safety/protection circuits
• Common symptoms: no response to buttons, dead/blank display, unexpected cycling or beeping, control error codes, or visible damage on the old board

• Disconnect power before servicing and verify no voltage is present
• Use ESD precautions; handle the PCB by the edges and avoid flexing it
• Photograph/label connectors; transfer each to the same location on the new board, matching any jumpers or DIP-switch settings if present
• After installation, restore power and run the model's test/diagnostic or a cycle to confirm proper operation
