I noticed the 2018 post and I have the same problem and question.
Does anyone know what the blinking LED lights on the Fridgidair FFTR1022QM with main board #5304498695 means.
Everything else on this fridge tests perfect and replacing the main board gave the same blinking lights and no run.
Any ideas. Oh that's right this thread is 2 years old with no takers.
Moderator what is to be done?
