this subzero freezer compartment did not free, but stayed cool. The problem was that defrost limit switch went bad, so when it was going to defrost cycle heater never came on, so it builded up snow and ice on evaporator coils and air stopped circulate. I replaced that little thermostat, and melted down ice.

remove all the drawers and unscrew the frame that holds the drawers. Free the the drain tube (need to unscrew the clamps that hold the tube to the back wall). Pull it up from the bottom hole where it drains into the pan and free it from the top drain pan. Most likely it's plugged with **** and fungus and yecchy stuff. Clean it out and reinstall it.

It's a big door. You should check the refr drain. If that's blocked it will be harder to open than normal.

Just frost or a puddle? If it's a puddle cause by melting frost with no where to go then you had my problem. A clogged drain. First defrost the drain, a hair dryer works well, blow or snake it out then install the factory drain heater fix. Plugs right in and works like a charm. I've had my sub zero 550 for more years than I can remember. I'd buy another one in a minute. Good luck!

yeah vacuuming behind the fridge is a good start this will help the fridge preform better as when dust builds up on the condenser it will cause the discharge to be hotter than it should be making the cooling in the case not as efficient. i would start by removing the pannel in the fridge and seeing if any ice is on the evaporator

Most likely would be a failed defrost heater. Call an authorized servicer.

Is this on the 315I unit? The only way is to remove the cabinet, not easy but very possible and time consuming. If you have never done this, I would seek assistance by calling someone out. This job takes less than 2 hours to complete assuming there is no other issue with this unit at the time of service.

I hope this helps.

This job is difficult to walk someone through on the computer and the phone. No simple access.
