How to Clean Condenser on a Sub-Zero Refrigerator
Why clean my Sub Zero refrigerator condenser coils?
Keeping the condenser coil clean on your refrigerator is a major factor in efficiency and lasting performance. A dirty condenser coil causes the compressor to run too hot which can damage the compressor, cause the refrigerator to run too long, and cause a no-cool situation. It is very important to clean condenser coils on forced-air refrigerators such as side-by-side and built-in models at least twice a year (if you have a refrigerator with the black coils mounted on the back, these coils don’t require semi-annual cleaning). CONSERVE ENERGY: CLEAN YOUR RADIATOR AND REFRIGERATOR COILS! Dirty coils force your appliances work harder, using more energy than clean coils. Regular cleaning enhances radiator and refrigerator performance, extends their lives, and can save you up to 6% on your energy bills! The refrigerator has a compressor that forces refrigerant through coils in the freezer and on the refrigerator’s exterior. Evaporator coils in the freezer remove heat from inside. This heat is emitted into the room through the exterior condenser coils. If the exterior condenser coils become dirty, they are less efficient at transferring heat into the air around the refrigerator and forcing your appliance to work harder. How often should I clean my refrigerator condenser coils? For maximum performance, it is recommended you clean your refrigerator condenser coils at least twice per year, more if you have pets. How do I save money? Routine cleaning of dryer vents/ducts and refrigerator coils allow your appliances to work freely, without energy-absorbing dirt and grime found on all used appliances. Clean appliances result in lower energy bills, and may reduce your risk of a fire.

Cleaning Condenser on a Sub-Zero Refrigerator
Step 1
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.
Step 2
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.
Step 3
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.
