Performing Routine Maintenance on Your Sub-Zero Condenser

In Depth: Sub-Zero Condenser Cleaning & Maintenance

 

In order to perform maintenance on your Sub-Zero you must first locate the condenser. The condenser accumulates dust and must be vacuumed and cleaned yearly. The condenser will be on the mechanical shelf, which is located either above or below the unit. All mechanical shelves will be covered by a grate. This grate will be opened to reveal the mechanics, which the condenser is a part of.

For most 500 & 600 series units the shelf will be located above the unit. To expose the shelf, first remove any screws which may be holding it in from the upper door frame. Simply open your refrigerator door and look up, you will see screws in the door frame. Some units may not have any screws. Remove the grate by pulling it towards you and removing any hooks (either 1 or 2) which are attached. This will free the cover to be pulled up and out. Once the mechanical shelf is exposed the Condenser will be located on the right side. If the unit has not been maintained the condenser may have a layer of dust covering it.

On many other units such as the 700 series, the mechanical shelf will be located below the unit. The grate which covers it can be removed by first removing the lower most drawer and unscrewing the four screws holding the kickplate.

For newer units such as the BI series. the grate is held opened and closed by spring loaded hinges. In order to reveal the mechanical shelf simply lift the cover up with a small degree of force. The cover should stay in place once opened fully, but if it doesn’t stay open try to prop it up with a long screw driver or something similar.

Once you have located the condenser simply take a vacuum cleaner and move it across the face of the condenser to remove all visible dust. Using a brush attachment on the vacuum will also help to loosen up dust which lies within the condenser. We also recommend wearing a dust mask if possible, especially for older units which have been accumulating dust for many years.
