An ER-FF Code is almost ALWAYS caused by frozen condensation build around the evaporator fan motor. Typically this is caused by the defrost controller telling the PCB to start the cooling cycle too soon after defrost. The condensation / steam from defrost gets frozen and builds up. If the fan is stopping ( or slowing down ) because of ice b.u. you should hear a chopping / scraping sound until the door is opened. If it is a frost only issue, defrost the box and wipe out any condensation / water. If it is persistent change the defrost controller.

The fan motor could be bad but it is unlikely. We have only come across 1 bad one in hundreds on ff codes. Suspect the frost / ice.
