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.

SOURCE: 650 sub zero that has a vacuum condenser message returns.

I have seen this many times and have fixed the problem many times. You may notice a ball of frost or ice build up in the fresh food compartment, This is because you have a leak in your evaporator coil and it needs to be replaced. It is a pretty costly repair but well worth it in consideration to what you paid for this unit or what the cost of a new one would be. Because it has less freon in it is why the compressor is running longer and causing message to pop up. Have the evaporator replaced in the section that is giving the issue and this will solve your problem with the unit.

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).

Vacuum condensor light flashing and the refrigerator won't get colder than 51 degrees.


The light is indication a problem with the condenser coils being covered with dust/dirt and cannot dissipate the heat energy absorbed by the system in the evaporator coils (freezer). Or the condenser fan is not running. Clean the condensor and/or check the fan.
