- How to clean the condenser
- "Service" or "Vacuum Condenser" is flashing
- 600, 500, 200/300 Series or Model 430 running constantly or not cooling
- Sub-Zero temperatures are warm or hot
- Is there a chemical cleaner or degreaser that can be used to clean the condenser?
- There is a screen cage in front of the condenser. Can it be removed?
- How to remove the filter screen blocking the condenser?
- 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. Refer to the photograph of the caged condenser below.
- 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.
