What if my Sub-Zero product is flashing “Vacuum Condenser” or “Service”?

If your unit is flashing “Vacuum Condenser” or “Service” the main control board has registered unusually long run times on your product.

If this occurs, one cause can be a dirty condenser. The condenser should be cleaned regularly. If it has been more than six months since the condenser has been vacuumed; clean immediately, then turn your unit off and back on.

By cycling off your unit this message should be cleared. If your condenser is already clean or the “Vacuum Condenser” or “Service” message returns, call for service, there is a problem.

Note: For help with cleaning the condenser on your specific unit, refer to your owner’s manual, call Sub-Zero Customer Care at 800-222-7820, or visit

What if the electronic controls on my Sub-Zero, Wolf and Cove product are not responding?

On rare occasions electronics can lock up. We have all experienced this with our computers. If this occurs it can often be resolved by cycling off (re-booting) your unit at your house electrical panel. Cycle off your circuit breaker to the unit; then cycle back on to re-boot.

What information should I provide when calling for service?

In addition to address and phone number, it is a good idea to have model/serial numbers and date of purchase of the Sub-Zero, Wolf, and Cove product needing assistance.

Why is Factory Certified Service better than non-certified service?

Factory trained servicers get hands on training on all Sub-Zero and Wolf products the first year the products are released.

Factory servicers work on Sub-Zero and Wolf products for two years while the products are under the manufacturer’s warranty. This allows the factory servicers to be extremely knowledgeable about your Sub-Zero and Wolf product.

If your product needs a part to resolve your service problem, that part may have an extended part warranty. Your factory certified servicer will know this and make sure you get any warranty help that is available on your product.
