Error Code Er FF
This code is not to be confused with the O FF or demo mode error message. The "Er FF" error code indicates a problem with the unit's freezer fan. The freezer fan controls the temperature in the freezer. The source of this error is most likely ice buildup. As with the Er IF error, allowing the unit to thaw should resolve the issue. Contact customer service if the error code continues to be displayed after having thawed the unit.
Hope helps.
Error Freezer Fan
Remove back wall from inside freezer and clear frost / ice obstuction from freezer fan. If no blockage found, replace fan motor.
SOURCE: error message Er FF
er ff means that the control board is not sensing evap fan motor operation this means either a bad fan motor ice in the fan motor or bad control board. you can verify fan operation by opening freezer door and feeling for old air blowing from back of freezer compartment. you will have to push in the light switch to get fan operation.
for corndo that has same problem you actually have a different problem. er dh means the control board is not sensing defrost heater operation. the most common culprit is a bad defrost sensor. message me back if you need instructions for trouble shooting..thx peyton
SOURCE: What does message: Er FF mean?
That means the freezer fan is blocked, you need to order a new High voltage board, the ice has built up enough from not defrosting that it is interfering with the operation of the evaporator fan.
SOURCE: I have a LG GR-L207DUZA ''er ff''
i dont have the manual however.. this could be your freezer fan is perhaps seized.. you can test this by leaving your freezer door open to raise the temp and wait ti see if your fan comes on.. this may take upto 10 minutes so be patient
