I have a Frigidaire refrigerator. The error codes messages are EF and SY. The part # is: 241509402 and model # is: LGHS2634KP0
ANSWER Hello D. W.
The error code that you are getting indicates a Evaporator fan 241509402 failure. You want to check the wiring at the fan motor and at the control board. Check for 12vdc to fan between red and brown wires. Check for variant voltage (depending on high or low speed) between yellow and brown. If it checks ok then replace the Evaporator fan. If error code still exists then replace main control board 5303918514. 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
