my sub zero 650 is putting water on the floor. it appears to be a steady drip beside the drainpan under the fridge. it produces quite a bit of water. i've checked all the waterline fittings and drains and all seem to be working properly. what do you think?

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!

My ice maker on the Subzero 650 is up and running again. After checkig the tray and shutoff mechanism thoroughly I checked the display in the fridge aea and noticed a "service icemaker" indicator. I turned the icemaker off and then on again with no change. I then turned the power to the entire refridgerator/freezer unit off, waited ten seconds, and thurned it back on. This apparently must have reset some type of logic because the icemaker immediately began to cycle (ice ejector began to turn slowly) and then I heard the water soelenoid turn on to inject water into the ice trough. It's been 24 hours now and the icemaker tray is filling up nicely. I guess my icemaker just need to be rebooted. The miracles of modern technology. I appreciate the suggestions posted in response to my posting as well as the postings of others with similar issues as well as te corresponding suggestions. All of these together lead me to investigating areas that ultimately lead to resolution. I probably would have called for an expensive repairman if not for this forum. THANKYOU!

Sub-Zero 550 water dripping on right side of freezer forming ice on draw

I have a Sub-Zero 550 and water is dripping onto the freezer draw and freezing making it hard to open the freezer. It seems like water is leaking out of the tray. How do I fix? How do I get to the tray and drain line to see if it is plugged up?

I had a similar issue that started about a year ago with my Sub-Zero 550. My freezer gasket actually tore after several times of freezing closed. I thought that a new gasket would solve it, but a second but related problem developed where I was getting alot of condensation under the left side of the unit, with the water dripping onto the floor...eventually staining the hardwood floor in front of the unit.

I traced the problem to a clogged condensation drain pipe in the refrigerator. It is a corrugated pipe that drains a trough behind the crisper drawers. My pipe was clogged with black sludge and frozen down below. The condensation in the fridge would overflow out of the trough and leak below the crisper drawers, down out through the gasket.

To resolve, I used a piece of solid thin wire folded in half and twisted with a small loop at the end to fish out as much sludge as I could. Then squirted hot water into the pipe until it totally unclogged. I believe this will solve the problem without any need for a heater underneath the unit. The 550 worked fine for 4-5 years before this happened.

Freezer Drawer Stuck

Hi! Our subzero's freezer drawer is closed shut and can not be opened. I have tugged on it and tried to pry it open with several plastic utentils to no avail. I can't help but wonder if it has frozen shut. The ice maker stopped working a few weeks ago. Since we have another freezer, this was not a big "hurry to fix" item. Well, a few nights ago, I noticed that a few cubes had fallen. I haven't reached into the freezer in a couple of days, so I am not aware if the ice maker contined making ice, and somehow overfilled and froze the drawer shut? I turned the freezer off about 6 hours ago, hoping that if it is frozen, the ice will melt and the drawer open. Does anyone have any suggestions? Thank you!

Our 550 bottom freezer drawer froze shut earlier this week and the motor made an unusual sound, like it was working too hard. Two of us eventually were able to open the drawer to find that it had frozen shut due to a leak which filled the ice tray solid and then adhered to the actual door, freezing it shut. We emptied the fridge and freezer, turned the control dials down to 0, but neither the motor nor the light would go off. We finally killed the circuit breaker to get the appliance to shut down. It's cleaned and defrosted and we noticed that the gasket has torn in three places, two on the fridge door and one on the freezer door. The freezer door could be from our tugging, but the refrigerator door is normal wear and tear. We filled the tears with some kind of putty and when it is dry we will start everything up again. This is not the first problem of this nature we have experienced with our subzero 550, but it is the most dramatic. Each previous time we have called a repair man out and he has been unable to fix it.

Sub-Zero 550 Freezer Problem

The freezer on my mid 1990's Sub-Zero 550 just recently stopped working. The fridge still works perfectly though. Here is what happened:

We are remodeling our kitchen and moved the fridge to our living room (so now it is on thick carpet). During the move, my wife pulled the drain pan from the bottom to clean it off as it was filled with liquid and what seemed to be green mold that was very difficult to clear. We just slid the pan back under the fridge, but I don't know if it is in the right place as it is on carpet and hard to fit (not sure if this is a problem).
I first noticed that all the ice melted and food thawed out after we moved it. I looked around a little and found that the compressor switch (under the fridge at the top of the freezer, in the back left) that the drawer hits was a little lose and so the drawer did not always make contact (the result being that the compressor did not turn back on). I actually pushed the switch back in so it was being properly touched/activated. I even just taped the switch down so it does release and turn off the compressor EVER. I know the switch works because you can hear the compressor lightly hum when you push it in. (Note: also, the lights in the freezer work fine as well the light switch.) However, I came back in the morning and the freezer was still not cold. Any ideas? I felt the coils under the freezer and they are not cold or warm...is that how they are supposed to be?

HELP!

Hi have you checked that the pipes on the back havnt been damaged in anyway and also when you move anything like a fridge or a freezer you are supposed to leave it off for a couple of hours so that the gases can settle you could give this a try just leave it off for a couple of hours if you done this after moving it then that wont be the problem because if the gases didnt settle it could cause the frezzer to stop working properly.
Are you confident in taking the back off at all thats if it is able to come off on your model if it does come off check that none of the pipes are frozen if they are switch it off leave for about an hour then use an hair dryer to melt the ice.
If ice is the case then melting it will get your frezzer working again but make sure all the ice is melted.
Make sure you check none of the gas pipes on the back became damaged if this is the case you can get them regassed for a small fee.
Let me know how you get on and ill look up your model number then i should be able to assist you further ok let us know what you do speak soon

Pull the drawer all the way out until it stops. Then lift the front of the freezer drawer (a couple of inches), and pull out further (4-6"). The front will then lower to the floor. Lift the back of the drawer upward and slid the entire drawer forward. You may want to protect your floor. I did the above with the freezer drawer full and scratched my floor a little...

Ice in Refrigerator Section

I accumulate ice in the left rear section behind the produce draw. Also, water drips on the floor in the left front corner under the pull out freezer draw. The ice forms in the refrig and needs to be chopped out with a knife after a few weeks time. This cycle keeps repeating

there are 2 possibilities. first the drain is blocked causing water to overflow from the defrost water gulley at the bottom rear of the inside of the fridge. this can form ice as it is close to the division between fridge and freezer. second, the .fault of ice growth can be caused by breakdown of the cabinet insulation. of the two, the first is the moree likely. to test drain is cloear, pour a little water down the drain. if it does'nt flow freely, push something flexible down the drain hole till blockage is clear

vacuum condenser light of sub zero 650 is on - how to clean it

How to vacuum the condenser

Posted by on

Answer

  • Most Helpful of 1 Answers

We recommend vacuuming your condenser every 3 - 6 months. Cleaning the condenser is important for the overall operations of the unit including cooling functions. A dirty condenser may lead to warm temperatures in the refrigerator and freezer. It may also cause the unit to run excessively. It may contribute to condensation or frost inside of the compartments. If the condenser is not cleaned properly it may even cause premature failure of mechanical components in the unit. Condenser Cleaning - All Models Before cleaning the unit, shut the electricity off at the control panel. When you clean the condenser, wear gloves to avoid injury from the sharp condenser fins. Use a soft bristle brush and vacuum to remove dust and lint from the condenser. To avoid bending the condenser fins, be sure to vacuum in the direction of the fins, up and down. Clean the condenser every three to six months or sooner if you have pets. 600 Series Framed and Stainless Steel louvered grilles: First remove the grille screws located at the bottom of the grille. Tilt the top of the grille forward and release the springs from behind the grille, then lift off. Overlay Panel Grille: To remove, lift up then pull out at the bottom and down to release from its mounting bracket. Remove the two black screws in the lowest louver of the grille. Tilt the bottom of the grille out and away. It will release from the top of the grille. Model 601RG Stainless Steel Grille: Remove in a similar fashion as the overlay grille panel. 700 Series All Units: At the bottom of the unit, remove the four screws holding the kick plate/grille in place. It will then slide forward, giving you access to the condenser area. 400 Series 424/424FS At the bottom of the unit, remove the screws holding the kick plate. The condenser is located behind. 427/427R: Remove the four screws holding the kick plate/grille in place. It will then slide forward, giving you access to the condenser area. 430: First remove the screws located at the bottom of the grille. NOTE: These screws (Phillips head) are accessed with the door open. Tilt the top of the grille forward and release the springs from behind the grille, then lift off. 200 Series 245, 249, 315W Remove the kick plate at the bottom of the unit, giving you access to the condenser area.
