My top mount Freezer is cold enough but I can't get the Refigerator never drops below 40 degree max. It usually runs at 40-50 degrees if we open the door just once. The evap is not frozen and it does go through its defrost cycle just fine. Also, I have removed the damper from the freezer and made sure their are no obstructions on the return vents. I bypassed the thermostat and had it run for over 4 hours and it still never gets lower that 40 degrees. The compressor also runs very hot! Any ideas?

Thanks for the reply.
I did check the door seal and it is in great shape. the defrost system does not run consistantly and does in fact turn off and on correctly. Their is no condensation anywhere and no ice forming around the evap. I might also mention that I always kep my condenser cleaned and all fans work properly. Am I right in thinking that a refigerator temp should be at 33 - 38 degrees if it has been closed for several hours? Also, does a compresor ever just start to go bad or loose it effeciancy?

Unfortunatly this one is 7 years old! The question that I have is can a compressor keep running (mentioned very hot from previous post) and loose its effeciancy?
