Dimitri serviced our SubZero fridge/freezer. A day to assess and get the new icemaker part and a hour or so the following day to replace the part. Dimitri was great at communication, punctual, and performed the job with a pleasant demeanor and professionalism.

Dymetrey was awesome, best service ever. The most knowledgable about SubZero! He diagnosed the problem in no time, ordered the part. Overnight the part came in and Dymetrey texted me for an install time. Onsite he did an outstanding job! Could not have been a better service. He has won my business, anytime I have an issue, I will call on the company!!

Common Sub-Zero Refrigerator Problems We Fix

Sub-Zero Refrigerator Not Cold

When your Sub-Zero fridge loses its chill, it is often tied to airflow issues, failing compressors, or control board problems. We restore proper cooling fast.

• Sub-Zero Freezer Not Cooling

A warm freezer can lead to spoiled food and ice buildup. We fix evaporator issues, sealed system problems, and faulty sensors affecting freezer performance.

Sub-Zero Fridge Water Leak

Water pooling under or inside your unit often points to clogged drain lines, damaged water valves, or cracked tubing. We stop leaks at the source.

Sub-Zero Refrigerator Ice Maker Not Working

No ice or misshapen cubes can signal water supply issues, bad ice makers, or sensor failures. We get your ice flowing again.

Sub-Zero Fridge Not Working

If your refrigerator is completely unresponsive, the cause may be electrical faults, control failures, or internal component breakdowns. We diagnose and bring it back to life.

Sub-Zero Door Gasket Replacement

A worn or torn gasket lets cold air escape, forcing your fridge to work harder. We replace door gaskets to restore efficiency and temperature stability.

Sub-Zero Refrigerator Repair in Denver — Frequently Asked Questions

Yes. We service Sub-Zero appliances across all current and legacy product lines — 700 Series, 600 Series, Classic Series (BI series), Pro Series, and integrated column units. We also service older Sub-Zero models where parts are available. If you’re unsure whether we can help with your specific model, call us — we’ll tell you directly.
same-day service is available when scheduling capacity permits across Denver, 7 days a week, 8 AM to 8 PM. Call us in the morning and we’ll do everything we can to have a technician at your home that same day. We stock parts for the most common Sub-Zero faults, so most repairs are completed in a single visit.
Yes. We offer same-day service when scheduling capacity permits 7 days a week, including weekends. If you have a Sub-Zero appliance that has failed with food at risk — a refrigerator or freezer no longer holding temperature — call us immediately. We prioritize these calls and treat them as urgent.
We use quality replacement parts that meet or exceed Sub-Zero’s original factory specifications. Original OEM parts are used where available and practical. When an OEM part is discontinued or has an extended lead time, we source a carefully vetted equivalent that performs to the same standard. If original factory parts are required for your situation, let us know — we’ll source them and advise on timing.
This is one of the most common Sub-Zero issues. In many cases, the freezer continues producing cold air while a faulty evaporator fan, blocked airflow, dirty condenser, or failing defrost system prevents that cold air from reaching the refrigerator compartment. The problem is often repairable if addressed early.
Water leaks are commonly caused by a clogged defrost drain, frozen drain line, damaged water supply tubing, or a leaking water filter connection. Ignoring the leak can lead to floor damage and moisture buildup inside the refrigerator.
In many cases, yes. Sub-Zero refrigerators are built to last significantly longer than standard refrigerators and are often worth repairing even after 15 or 20 years, provided the sealed refrigeration system is still in good condition. A professional inspection can help determine whether repair is the most cost-effective option.
As soon as possible. Because Sub-Zero refrigerators are designed to preserve food at precise temperatures, any cooling failure should be addressed quickly to reduce the risk of food spoilage and prevent additional damage to refrigeration components.
