The FF error code indicates that the freezer fan motor is defective. You can also get this code if ice is preventing the fan from turning. -For LG French Door refrigerators, check the gaskets around the doors for damage or possibly the gasket is coming off the fridge door

Hello, Petra -

You have not stated the make and model of your refrigerator. Therefore, I have to guess what the error code FF means.

It MAY mean there is a problem with the freezer fan. The fan could be defective and need to be replaced. Or, there is ice built up causing the fan not to operate.

Or, the FF error code could mean the temperature control in the freezer has failed and the freezer temperature is rising.

Depending upon the manufacturer and model number of your refrigerator, the FF error code may mean something else.

Best wishes.

For LG A FF error code indicates that the unit has detected an issue with the freezer fan. This can sometimes be caused by frost buildup.

Might need a freon top up. If the compressor is functioning there may be in sufficient freon . This can be topped up. A repairman/technician can diagnose this fairly quickly

FF is usually a Freezer Fan error code. A qualified service tech needs to look at the unit, checking for iced over fan motor, loose plug connection, ect. Pleazer Appliance...
