Refrigerator compartment too warm; display shows FF or flashes FF; freezer may still be cold.

Safety first: Unplug the refrigerator or switch off the dedicated circuit breaker before removing panels or handling wiring. Use insulated tools and avoid working on wet floors.

Step 1 – Verify actual temperature and airflow:

• Place an appliance thermometer in the fresh food (refrigerator) section for at least 20 minutes. Confirm if the temperature is actually high (above 40°F / 4°C).
• Open the fresh food door and listen for the evaporator fan (usually behind the rear interior panel). You should hear a small fan running when the compressor is on and the door switch is held closed.
• Check for strong airflow from the top rear vents; weak or no airflow indicates a fan or damper issue.

Step 2 – Check for blocked vents and overloading:

• Ensure food items are not pushed against the rear wall or covering the top vents.
• Remove any large trays or boxes blocking airflow between freezer and fresh food sections.
• Allow several hours for temperatures to stabilize after rearranging.

Step 3 – Inspect the fresh food evaporator fan (if no airflow):

• Unplug the unit.
• Remove shelves and the rear interior panel of the fresh food section (on many GE Monogram French-door models, the fan is behind this panel).
• Check the fan blades for ice buildup or obstructions. Clear any ice with a hair dryer on low heat, keeping it moving to avoid warping plastic.
• Spin the fan blade by hand; it should move freely. If seized, noisy, or not running when powered, the fresh food evaporator fan motor likely needs replacement.

Step 4 – Check the fresh food thermistor:

• Locate the thermistor (small plastic-encased sensor clipped to the liner or behind a small cover in the fresh food section).
• Inspect the wiring harness for damage or loose connections at the main control board (usually at the top or rear of the unit).
• If you have a multimeter and the tech sheet, test the thermistor resistance at known temperatures. Replace if readings are out of GE specifications.

Step 5 – Inspect the air damper (if equipped):

• Locate the air damper assembly between freezer and fresh food compartments (often behind a cover at the top left or top rear of the fresh food section).
• Check if the damper door is stuck closed by ice or debris. Gently defrost any ice and verify the door can move freely.
• If the damper does not move during operation or is physically broken, replace the air damper assembly.

Step 6 – Control board evaluation:

• If fan, thermistor, and damper test good but FF persists, the main control board may not be reading temperature correctly.
• Inspect the board for burnt components or corrosion. Replacement of the board is typically required if faults are found.

When to call a technician: If you are not comfortable testing thermistors or accessing the control board, or if FF returns after replacing the fan, contact a GE Monogram–qualified technician for advanced diagnostics.
