I have a sub-zero stand type freezer model 501F , the top portion of the door is not closing all the way causing the food on the top shelf not to freeze however the bottom shelves are good. How do I troubleshoot this issue? Thanks

Fridge and freezer cabinets aren't anywhere near as rigid as they look - it is important they stand on firm level ground and using a spirit level and any adjustable feet the cabinet should stand level and four-square. This is good for the compressor too.
Once level and square the door will remain in whatever position it is placed.

There isn't usually much or any adjustment available at the door hinges but if there is the door should be adjusted for the best fit and the magnetic door seal should close to the metal of the cabinet and create an almost airtight seal.

If after this process the door doesn't fit and an almost even gap between the door and cabinet isn't achievable, the door might be warped - the door also isn't rigid; very flimsy and flexible without the plastic liner and so any warp in the door is likely to be caused by a badly fitted liner or a poor quality liner...

Hi there, We haven't a 756TC Sub-Zero that has lots of condensation under the crispy shelf. I'm pretty sure it's clogged up and also we need to get all door gaskets from the fridge and freezer drawer replaced since they are all cracked. Also my oldest son broke the arm of the ice dispenser when he abruptly opened the freezer drawer ?? I have 3 questions: 1- How can get the drainage system unplugged? 2- Where can I buy the gaskets from and what is the part number for me to order it ? 3- What is the part number for the ice dispenser arm? Can I buy it separately or I will need to replace the entire ice dispenser? I need this urgently done because I don't want my fridge to get damaged because it's condensation and gaskets problem.

Suggest first add up the costs to fix everything needed on your unit verses its age. My guess would be more cost effective to buy a new fridge.

Sub-zero refer.611/s is working fine but the freezer compressor has been running 24/7 for the last 2 weeks. Sometimes the freezer drops from it's setting of zero to 16-. Coils are clean and fan works.

I think it isn't fine because if a fridge/freezer that is otherwise healthy runs continuously (due to a thermostat fault), it would be colder than you could imagine with lower than arctic temperatures in the freezer compartment, minus 30-40 C for example.

The conclusion must be your fridge isn't fine.
Proper freezer temperature, incidentally, is minus 25-27 C for food to have a reasonable lifespan with minimal deterioration. There is no benefit from being colder but significantly warmer would mean the freezer contents should be replaced much more often - the freezer compartment of an old fashioned fridge (about minus 5) was reckoned to give fish, meat and dairy up to one month safe lifespan.

A fridge that runs continuously (where the thermostat is good) could have a refrigerant loss resulting in a huge drop in efficiency, the insulation could be failing, the compressor could be failing or the de-icing panel could be permanently switched on - or any combination of these things.

I note you say the coils are clean. If the refrigeration system is good with the compressor running continuously the coils will be hand-hot.

Many times a freezer and/or refrigerator do not work right because of a dirty condenser coil...there are also many other things that can go wrong.

If you are hearing a clicking or buzzing then check out the last two tips.

If your refrigerator is running but warm, then…

Check out this tip that I wrote about that... it is a great place to start trouble shooting your unit...and something that you can do rather then calling a repair person to do a simple thing for you...

Our Sub Zero 736TC has

The drain at the rear of the fridge is possibly clogged. To check: Remove all the shelves and crisper in fridge, remove the lighting diffuser panel you will then see 3 screws at the top of the back panel. Undo these screws and lift the panel up and out. This will expose the drain trough at the rear base of the fridge compartment. There is a small drain hole right in the middle of the trough. I found mine to be completely clogged and the trough was overflowing into the fridge compartment.Use a small wire (I used a twist tie wire) to poke into the hole and open up the drain.This should stop the problem, as any water will now drain to the tray in the base and evaporate.
I also found that the door was really hard to open immediately after it was closed and after I cleared the drain this problem wnet away (I think the clogged drain was allowing a vacuuum to be created in the fridge when the door closed.

Why is my sub zero fridge model 590 warming up?

Hi fridges will warm up on the outside as they remove heat from the inside. excessive heat with not extreme cooling inside the fridge indicates a possible degridation of coolant fluid or a leak. as the motor tries to cool the fridge the thermostat inside stays on as the tempreture inside has not been reached. if you hear the motor/ pump continually running this will indicate a cooling problem.

I have a sub zero

It is possible to replace the connector but might be hard to find the exact match. Maybe consider going to Fry's or a local electronic hobby store and replace both sides of the connector. You might even be able to find one that does a better job at moisture sealing...maybe an auto parts store that has replacement connectors for the engine compartment.

Do you still have a manual or can tell me the watts power consumption of the 532?

I'll look into your question. Sounds like a sticking icemaker water valve, but I'll have a look.

How do remove the wood panels from a sub-zero 561 refrigerator

When you open the door, you will see screws holding the handle in place. It would be best to have an extra set of hands to support the handle as you remove the screws. Once all the screws are out then the handle will come off and the panel will slide out. Sometimes you will need to remove the top trim as well.

My sub zero 601r no cooling

How soon did you start it up after you moved it & put it in its place?
If you plugged it in to soon after moving. Oil may have still been up in the wrong place of the compressor. Unplug it for about an hour. Then plug it back in. By plugging it in to early after moving you could have burnt up the compressor. This happens often.

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!

Sub-zero Refregrator 352 Freeze cooling properly, but Refregrator only cools to ~50f. Stays off until ~70f, when set at lowest temp (10).

Fans working and air flowing thru the cooling coils?
The inside fan warms the evaporator, or cooling coil. If this coil does not go thru a defrost cycle or if there is ice build up to the point no air gets across it, that could be the scenario.Then it would need defrosting, or inspection to make sure there is free air flow both inside and outside the fridge, including the defrost timer if present. If all this checks out ok, then the refrigeration circuit is to be looked at by a technician.

Sub Zero fridge. Door has too much suction. If

This "problem" may not be a problem at all. When you open the door of a cold space you admit warm air. The colder the space is before you open the door the more quickly the warm air you admitted by opening the door shrinks (contracts) as it meets the cold surfaces. This effect causes a short term vacuum in the space. The vacuum prevents the door opening until the internal and external pressures equalize again. This can take several seconds. There is a drain for draining defrost water from the compartment that has a water "trap" in it which is intended to minimize the effect. In some models a gurgling sound can be heard when door is closed as the vacuum tries to **** the water trap back into the compartment.

If you haven't noticed this happening in the past there can be several reasons.

Possibly you just never noticed the effect before.
If your refrigerator has less stored in it than usual the air exchange when you open the door can be larger than normal and the volume of warm air admitted may take longer to "shrink".
The thermostat for the compartment has been turned down without your knowledge or has failed making the compartment colder than usual.Take temperatures. Refrigerators should be 36-42 degrees while freezers should normally be close to zero.
The drain for that compartment is clogged and needs to be cleared. A turkey baster with hot water can usually clear the drain.

Except for a faulty control and the clogged drain the other issues are no "problem" and merely a function of the "tightness" of the insulation of the refrigerator
