We get error code Er FF
Answer Hello Neil. The FF error code indicates that the freezer fan motor 4681JB1029A is defective.
A loud fan noise is coming from top upper of the freezer which stop when I open either side door.
Answer Hello Rose. Based on the information you provided, you will need to order and replace the fan motor 4681JB1029A in the unit.
I get error CF if I turn it off and turn it on, the unit will work. After 2 or 3 hours I will get the error message again.
Answer Hello Nagi,
The CF error code that you are receiving indicates that the condenser fan motor is not operating. If you pull out unit and pull the lower cover off, which is held on by phillips head screws, you can check the fan motor for something being in the fan blade causing it to not work. You can also test to make sure that the fan motor is getting proper power. The unit should get 12 vdc to the Condenser fan motor. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
