My sub-zero 650 fridge beeps when the door is open for awhile

SOURCE: leaking sub zero 650

I fixed my leaking problem by pulling out the vegetable drawer and checking the condensation drain hose. Sure enough, it was clogged and the condensation had nowhere to go but move out toward the front of the fridge, down the left side and onto the floor. Once that drain hose was cleared (with a bendable straw), no more leak!

Most likely you have a leak in the evaporator. Subzero warranties the parts for 12 years. Call them to find out what they will cover. They are agreat company and will be fair with you.

There are different handles depending on serial number. The older of the two is at the top of the door. The screws are covered with a magnetic trim piece. You can remove this by putting tape on the chrome and pull up. You can then tighten the nuber two phillips head screws. The newer model is on the door itself. These are held on with small set screws accessed from the bottom of the handle. You may get by just tightening the set screws. If not you need to remove the handle by removing the set screws. You can then tighten the standoff and reatach the handle. For the 632 same procedure except it will be on the side.

It went into self protection mode. Just leave it closed and when the compressor cools down enough, it will start. Once the ref starts to cool, the lights and such will come back on.

All of this assumes that no failure was caused by the long run times when the door was open

I have the Sub Zero 650. I am not sure if yours iworks same but what you do is use a 3/32 Allen wrench; as you push the handle into the screw on the door so that it is flush, you insert the Allen wrench in the hole at the bottom of the short vertical connector at top and tighten; repeat for upper or lower part of handle.
