Sub-Zero Freezer Repair you can trust
Freezer problems usually show up as frost, soft ice cream, a buzzing fan or an ice maker that quits. Because freezers run colder and defrost more often, defrost heaters, terminators, drain lines and fans are the parts we replace most — and we carry the know-how to trace the cause, not just the symptom.
Signature Appliance Repair is based in Oakbrook Terrace, IL and repairs Sub-Zero freezers throughout DuPage County, the western suburbs, the North Shore and the northwest suburbs. Call (630) 203-7302 or book online — we're open 7 days a week, 7 AM to 8 PM.

Sub-Zero Freezer Repair: common questions
Why does my Sub-Zero freezer have frost on the back wall?
Frost on the evaporator cover usually points to a failed defrost heater or terminator, a control problem, or warm air leaking past the door gasket. We test each and fix the cause.
Is my food safe while I wait for the repair?
A closed freezer generally holds temperature for many hours. Keep the door shut, and tell us when you book if food is at risk so we can try to prioritize the visit.
Do you repair Sub-Zero freezer drawers?
Yes, including undercounter freezer drawers and the drawer slides, gaskets and fans that go with them.
How much does an appliance repair visit cost?
The in-home inspection is $79 when you book online ($95 when booked by phone), and it's waived if you go ahead with the repair. After the diagnosis, your technician gives you the full price for parts and labor before any work starts.
Do your repairs come with a warranty?
Yes. Most repairs come with a 1-year warranty on parts and labor. Your technician will confirm the warranty for your specific repair before you approve it.
