- Use a soft bristle brush attachment on a 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.
- A limited number of units had a protective screen in front of the condenser.
- The screen cannot be removed as it is part of the sealed system. Vacuum it the same as the condenser.
- 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.
- Turn unit on and monitor temperatures.
- It may take up to 24 hours for temperatures to return to normal after condenser cleaning.
- For additional information, refer to:
- Clean the condenser every six to twelve months.
- Failure to clean the condenser could result in temperature loss or mechanical failure or damage.
