Frigidare Freezer and fridge 60 inch

Selling my Frigidaire gallery Freezer and Fridge build in 11/2015 Freezer is in perfectly working order! I paid around $7000 for the set up both units and the trim kit! The fridge is cooling to only 50 degrees! I am not sure what is wrong with it I never had a tech look at it! Model number Mod FGRU19F6QFA and MOD. FGFU19F6QFA. they are each 30 inch wide so 60 inch in total! I want to sell them as a package but willing to separate them if it makes sense! Call or text Jeff for more info show contact info
