Report "I am cleaning the condenser on my 600 series Sub zero (48 wide). I removed the outside grill on the top. Inside is another black mesh type grill with 6 screws that is over the condenser fins. I have removed the six screws but it still will not pull off to access the fins so I can vacuum. I tried vacumming through this grill and it doesn't do anything as the holes are too small to really do anything to the dust covering the condenser fins. Help!"
