The fridge would get stuck in a reboot until it faulted to the SY CF error code.
I began by replacing the main control board and initially the fridge wouldn't even turn on/start up. After digging into the problem it turns out the newer manufactured control board won't communicate with the older secondary display board above the water/ice dispenser. It would've been extremely helpful and time saving to have had this in

Can you please email me installation instructions for this main control board, part number 5303918498. My order did not come with instructions, and I'm having difficulty installing it. Thank you.Prestonleejones@gmail.com

Hello Preston,
Thanks for your question!
Pull out the freezer drawer and detach the lower grill.
Use a large flat head screwdriver to pull the control board housing down, then pull forward.
Note the orientation of the control board wire connections, then disconnect.
Pry out the test port plug and depress the retaining tab to remove the old board.
Snap-in the new Board and reconnect the old wiring. (You may not need the new wiring)
Replace the test port plug and slide back into place.
We hope this helps!

We have the Frigidaire gallery. We got sy ce code and the first troubleshoot was to unplug the fridge for 15 minutes. When plugged back in the code became sy cf. It has since gone back to sy ce. I know both are communication errors, but what's the difference? With both codes, the frige and freezer are working aside from ice and water dispensing and the user interface cannot be changed. I pulled both the main control board and the user interface board and both have solid connections and neither has any indication of burned or frayed wiring at or around the connections. How would you check the wiring between the 2 units? Both the main control board and the user interface board were replaced about 5 yrs ago, is this a common reoccurring issue on this fridge? Suggestions or solutions? Thanks

Hello David, Thank you for your inquiry. You can check the wiring with a voltmeter. The SY CE error code means there is a communications issue. This communication problem is caused by either a wiring issue, wire harness issue, faulty control board, or a bad user interface board. The SY CF error code typically means that your refrigerator has detected an error between the main control board and the user interface (the control on the Freezer door). If the refrigerator is working other than the ice and water dispenser, it is most likely an issue with the user interface board and we would recommend replacing it part# PS3503319. Good luck with your repair.
