Frigidaire FRS6R5ESBC new parts but still not cooling

I have side by side Frigidaire and I ordered the defrost/temp sensor, start sensor and capacitor.
Fan works inside, underneath also. lights come on and I can use the door switch to make it go into defrost.
Compressor vibrates and lines get cold underneath but the coils insode are not cooling AT ALL! Like the compressor is not on. Could it be the Defrost board? Freon/leak?
It just happened all of a sudden.
