Center divider strip between doors is extremely hot. Unit cooling fine on both sides but runs almost continually. Cleaned coils per directions in manual best I could, no help.
Did you check that the condenser/compressor fan was running.
And that it is blowing correctly.
I would also check the fan blades as dirty blades can drastically reduce air flow.
Also check that the rear cover vents and the kick plate vents are clean.
