Refrigerator displays EC or an error indicator without clear description; unit may not cool properly.

Safety first: Disconnect power before accessing the control board.

Step 1: Power cycle

• Unplug the refrigerator for 10 minutes, then restore power.
• If the EC code returns, proceed to inspection.

Step 2: Inspect main control board

• Remove the rear access cover to expose the board.
• Look for burnt components, discoloration, or bulging capacitors.

Step 3: Check connectors

• Reseat all connectors, ensuring they are fully engaged and not corroded.

Step 4: Replace control board

• If visible damage is present or the error persists after reseating connectors, replace the main control board with a Frigidaire Gallery-compatible part.

When to call a technician: Board-level diagnosis and replacement are best handled by a professional if you are not experienced with electronics.
