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

If your appliance 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 or schedule a service online, 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. If your unit is still not responding, don’t hesitate to call or schedule a service online.

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. Learn about what to expect from a ProAppliance Technicians service here.

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

Factory Certified servicers like ProAppliance Technicians get hands on training on all Sub-Zero, Wolf and Cove appliances the first year the products are released.

Factory Certified servicers work on Sub-Zero, Wolf and Cove appliances 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, Wolf and Cove appliance.

If your appliance 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.
