How to Clean Sub-Zero PRO48 Refrigerator Condenser Coils

Is your Sub Zero PRO48 refrigerator not staying as cold as it should? One of the most common reasons for refrigerators having trouble maintaining a cold enough temperature is dirty condenser coils. Built up dust and debris on your refrigerator condenser coils will make them work much harder than they should to keep your refrigerator cold.

Here are several symptoms that indicate dirty condenser coils on your Sub Zero PRO48 refrigerator:

  • Temperatures are warm or hot
  • The refrigerator is running constantly but doesn’t seem to be cooling
  • “Service” or “Vacuum Condenser” lights are flashing

How to Clean Sub-Zero PRO48 Refrigerator Condenser Coils

The steps for cleaning the condenser coils on your Sub-Zero refrigerator are fairly straightforward. We’ve put together a helpful step-by-step process for cleaning your Sub-Zero refrigerators condenser coils. If you follow these instructions and find that the problem isn’t fixed, it may be time to call a professional that can perform Sub-Zero refrigerator maintenance.

Address Error Codes

The first thing you should do is address any error codes that the refrigerator’s computer is sending. After cleaning, these error codes should not come back, if you find that it is still sending error codes after cleaning, call a Sub-Zero repair professional for a diagnosis.

Turn Off the Power

Press POWER on the control panel to turn off your refrigerator. Make sure to keep doors closed while the refrigerator is off to retain any cool air that is currently in the cabinet. If you’re going to have the power off for an extended period of time, make sure to remove any food that can go bad.

Remove the Grille Assembly

Located at the top of your PRO48, you’ll find the grille assembly. Lift and rotate this grille to gain access to the condenser area.

Remove the Water Filter

If your water filter is making it difficult to reach the condenser area, you can easily remove it for better access. Just make sure to put it back in when you’re finished!

Remove Dust from Condenser Area

Use the soft bristle brush on your vacuum cleaner to remove any dirt, lint, or other debris that is collected in the condenser area. If the vacuum attachment isn’t doing the trick, try a soft bristle paint brush to break loose stuck on dust. While there are many retailers that will try to sell you degreaser and chemical cleaners, these are not necessary for cleaning and not recommended by Sub-Zero.

Put Everything Back and Turn the Refrigerator On

Once the coils are clean, make sure everything is put back the way you found it in the condenser area and reattach the grille. It may take up to 24 hours for your refrigerator to return to the proper temperature.

Monitor the temperatures for a few days to see if the problem has been resolved. If it still isn’t holding the correct temperatures, or you’re still receiving error messages, there could be something else wrong with your unit.

Clean Every 6 to 12 Months

Regular cleaning of your condenser coils will extend the life of your refrigerator and ensure that it functions consistently.
