    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 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. NOTE: These screws (Phillips head) are accessed with the doors open. 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. Models 601R, 601RG and 601F Louvered Grille: 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.

How do i shut off and reset sub=zero 690 fridge?

Its not necessary when "Vacuum Condenser" light is blinking means That condenser is dirty. That light will come on if compressor running too long. Most common problem is that Evaporator coil in fresh food section is leaking freon. It still might keep temps ok, but compressor need to run much more to keep temperature you set. check back wall in fresh food section on left side at the middle, behind drawers. if you see moisture in one spot or a little bit of ice build up, then You will need to call people who can replace evaporator. It is pretty expensive fix. I made video how it looks to repair this problem. Thanks.

My refridgerator is a 550 sub zero and it will not freeze in the freezer and the temperature in the fridge is off as well. What do I do?

It is likely the condenser fan is not functioning or the condenser is plugged with dirt. You may need to open the compressor access panel to check. If you can hear the compressor running, and the condenser feels warm, the fan should be running. If it isn't, it probably needs to be replaced.

Sub-zero 550 refrigerator is too cold--icing at boottom near vegetable bins. Temperature is eratic--a lot of variation between top shelf and bottom and frequently shifting and changing.

It is very common for this refrigerator to have a freon leak in the evaporator.
Since you need a EPA license, This is usually beyond the scope for the home owner to repair.

Can you assist with this problem? The freezer of my Sub Zero model #690 is not freezing hard enough and a light blinks that says "service" next to the temperature control button. I don't have a...

Dear claymier,

I'm sorry to hear that your unit has a 'Service' indicator flashing. This message is displayed when the unit has had to run for an excessive period of time. This means that your unit is having difficulty cooling and as a result is running more often than normal.

My first suggestion would be that you turn off your unit and clean your condenser. Cleaning your condenser on a regular basis will help keep your unit running efficiently. While your compressors run, air is drawn through the condenser area where dust and/or pet hair can collect. Our recommendation is to vacuum this area at a minimum twice a year. Failure to do so could result in temperature loss, mechanical failure, or damage. Turn off the unit when you clean the condenser. This will reset the 'Service' indicator.

You will find instructions on how to vacuum your condenser in your Use & Care Manual. We also offer a video that provides clear instructions on our website, which you can view by following the enclosed link:

After trying this, if your unit is still having problems keeping temperature or if the service light has come back on, I would recommend that you contact a Factory Certified Service company.

I have a 690 subzero refrig that runs almost continually and temps jump around from 38-46..any ideas

I had the vacuum condenser message on my sub zero for about five years. I vacuumed it every six months (as per the owners manual) and the message would go out for about a day and then come back. I figured it was just a bad code.

Recently, my frigerator temp went from the normal 38 to 40 deg F to about 53 to 55 deg F. My freezer temperature was normal (0 deg to -2 deg F). My unit is under warranty (parts only) -- Model 560 -- so I called an authorized service company. They found that my evaporator coil was bad and replaced. I had to pay for labor and freon so my bill was about $300.

Since then -- my warning message is gone and my frig temp is at 38 deg F. Constant. No waivering.

So - for those of you with a Sub Zero with a wandering frig temp and with the "vacuum condenser" message on all the time -- I am suggesting that you get service out to look at it immedately. More than likely -- you have a freon leak and the frig cooling is insufficient leading to the error message ("vacuum condenser"). I am guessing that my frig was running all the time leading to a higher electric bill (potentially -- an extra $10 - $15/month * 12 months * 5 years of owning the house = $600 - $900 of money thrown out the window.

Hope this helps!

My light says "vacuum condenser". I cleaned coils and fan and turned unit back on. Light came back on in few days, also don't know where reset switch is. Thanks

Good day,
The power off/on switch is the reset proceedure on most Sub Zero's however, it initially comes on when the unit senses the temperatures are too high, leaving the compressor.
It also is a known fact that a Sub Zero condenser cannot be cleaned by vacuuming only.
Service techs use either compressed air or nitrogen with a hose to blow the condenser clean.
Lacking that, a good push -pull shop vac with a crevice tool makes a good substitute.
Remove top grille, and the cover plate for the compressors.
Aggressively blow the condenser out from both sides.
Make sure it is clean, by shining a light on the inlet side, and making sure you can see thru the fins.
It's ugly, dirty and makes a real mess,
But the option long term, is winding up replacing the compressor(s).

Sub zero wine cooler showing 78 and76 and says

Clean the condenser located under the unit. This may help. However, more serious problems involve refrigeration leaks shorted thermistors and non running fan motors. All are common. I recommend an authorized Subzero tech for this unit if cleaning the condenser does not help.

Although my sub zero 642 is holding the temperature, there is water leaking from underneath the refrigerator every day onto the floor. Sometimes it is heavier than others.

it's condensate from the evaporator coils. when the humidity collects on the coils, it should drain into a pan under the fridge that gets evaporated from the hot-side line. check to see if the condensate tube from the coils is still in the pan.
