A Sub-Zero refrigerator is a sealed system that never stops running, and in Thornton mile-high air is dry, and hard Front Range water leaves scale in ice-maker lines and water valves — so the condenser and the door seals take the punishment.

Sub-Zero Refrigerator Repair in Thornton — 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 Thornton area?
Yes. Thornton and the surrounding cities run off the same dispatch and the same number. Call (720) 740-2711 if you are not sure your address is in range.
What else do you check on a refrigerator while you are there?
Thermistor readings against actual cabinet temperature, and defrost heater and drain, before anything is condemned. Both are quick, both are common, and catching them on the same visit saves a second call-out.
How much does Sub-Zero refrigerator repair cost in Thornton?
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 refrigerator in Thornton?
Most Thornton calls are booked same or next day. We are open 7 days a week, 9am – 6pm on (720) 740-2711.
What goes wrong with a Sub-Zero refrigerator most often?
Condenser coils and the clearance behind the grille 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 refrigerator in one visit?
Usually. We carry the common refrigerator failures on the van; evaporator fan and the airflow path between compartments 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.
