That is definitely a Frigidaire built Kenmore refrigerator.
** I am trying to figure out what "E F" fault code means on this unit **
I'm afraid that is too new of refrigerator and I do not know what that error message would indicate. I'd have to look at the 'tech sheet' which should be with the appliance's wiring diagram somewhere on the appliance. You could also try contacting Frigidaire's customer support although I don't know how helpful they'll be being that it's a "Kenmore" product and is suppose to be supported by Sears. Sorry.
If you do find out, maybe you could post the results in case someone else comes looking for the answer.
