Designer Undercounter (DEU) Refrigeration and Wine Storage Condenser Cleaning

Topics:

  • How often should the DEU refrigerator condenser be cleaned?
  • Sub-Zero DEU Wine Storage running constantly or not cooling
  • Is there a chemical cleaner or degreaser that can be used to clean the condenser?

Answer:

Clean the condenser every six to twelve months. Failure to clean the condenser could result in temperature loss or mechanical failure or damage.

The condenser is found at the bottom of the unit, behind the kickplate.

To clean the condenser:

1. Address any Error Codes messages on the control panel display first. Search for information about the specific error to resolve it.
2. Turn the unit off. Touch the gear icon to open the settings menu, then touch the power key.
3. Use a soft bristle brush attachment and vacuum to remove dust and lint from the condenser area.
  • A paint brush, air compressor on a low setting, or a can of compressed air also work to clean the condenser.
  • Condenser cleaning chemicals and degreaser are available from several suppliers and online. They are not necessary to clean a Sub-Zero condenser and are not recommended by Sub-Zero.
  • If there is a build-up of dust or debris behind the screen that the vacuum does not reach, use an air compressor on a low setting or a can of compressed air to blow the condenser clean.
4. Turn the unit on and monitor temperatures. It may take up to 24 hours for temperatures to return to normal after condenser cleaning.

If these steps do not resolve the issue, no further troubleshooting advice is available. Contact Factory Certified Service to schedule an appointment for repair. Share any service indicators and current temperatures with the service company.
