A Sub-Zero freezer is a defrost cycle that has to complete every time, and in Walnut hot inland summers and hard imported water, a combination that ages condensers and ice makers at the same time — so the drain and the seals are where it goes wrong.

Sub-Zero Freezer Repair in Walnut — Questions
Are you an authorized Sub-Zero service center?
No. We are an independent repair company and are not affiliated with, authorized by, or endorsed by Sub-Zero. We repair these appliances; we do not represent the manufacturer.
What if you find a second fault while you are here?
We price it separately and you decide separately. Nothing beyond what you agreed to gets done without you saying so.
Do you cover the rest of the Walnut area?
Yes. Walnut and the surrounding cities run off the same dispatch and the same number. Call (213) 340-2171 if you are not sure your address is in range.
What else do you check on a freezer while you are there?
Evaporator coverage -- even frost or a cold spot, and setpoint against what the cabinet is actually holding. Both are quick, both are common, and catching them on the same visit saves a second call-out.
How much does Sub-Zero freezer repair cost in Walnut?
There is a flat $99 service call and diagnostic fee for the visit. You get the diagnosis and the price together in writing before any work begins, and you decide at that point with no obligation to proceed.
How soon can you look at my freezer in Walnut?
Most Walnut calls are booked same or next day. We are open 7 days a week, 9am – 6pm on (213) 340-2171.
What goes wrong with a Sub-Zero freezer most often?
Whether the defrost cycle is completing, end to end is where we start, and it is the answer more often than anything else. The full list of what we are called out for is on this page.
Can you fix a freezer in one visit?
Usually. We carry the common freezer failures on the van; the drain line for ice that has closed it off is the one that occasionally needs a part ordered, and we tell you the wait before you commit.
Is the repair guaranteed?
Yes. Repairs are backed by up to a year on parts and labor, and we confirm the exact coverage for your repair before we start.
