Expert Sub-Zero appliance repair for premium cooling systems

Sub-Zero refrigerators are known for their precise temperature control, dual refrigeration systems, and long-lasting engineering. However, when a Sub-Zero unit develops cooling issues, ice buildup, or a faulty sealed system, it requires a trained specialist — not general appliance repair.

Our technicians work with all Sub-Zero generations and configurations, including built-in Pro models, integrated columns, undercounter refrigerators, and wine preservation systems. We provide accurate diagnostics, genuine-quality parts, and long-lasting repairs tailored to high-end refrigeration technology.

Common Sub-Zero appliance problems

Sub-Zero units are premium and highly reliable, but they use complex components that require professional diagnostics. These are the most frequent issues we repair:

  • Sub-Zero refrigerator not cooling or cooling unevenly
  • Freezer warming up or losing temperature over time
  • Ice buildup on evaporator coils
  • Unit running constantly or making loud noises
  • Ice maker not working or leaking
  • Water leaking under the refrigerator
  • Control panel or temperature display malfunctioning
  • Wine cooler not holding steady temperature

Most of these problems require specialized tools and brand-specific troubleshooting, which our technicians are trained to perform.

Why Sub-Zero appliances break down

Sub-Zero refrigerators use advanced dual refrigeration, vacuum-sealed doors, and high-precision sensors. Failures can occur when any of these components are worn or obstructed. Common causes include:

  • Evaporator coil corrosion (common in older Sub-Zero models)
  • Faulty or weak compressors
  • Refrigerant leaks in the sealed system
  • Clogged or damaged condenser coils
  • Failed evaporator or condenser fan motors
  • Defective thermistors or temperature sensors
  • Ice buildup restricting airflow
  • Door gasket wear causing warm air intrusion

We identify the exact source of the issue and restore performance using professional Sub-Zero repair methods.

Unbelievable experience! My 15 year old Samsung washer stopped working (bad pump). I called them at 8:45am, they had a technician at my home in Huntersville within an hour. The technician, Dmitrii, confirmed the bad pump. I went ahead with the repair and he waived the $99 call out fee for doing so. He replaced my pump for an incredibly fair price. I was blown away that he actually had a pump on his truck for such an old washer!! He said he carriers more than 80 pumps with him! 🤯 In total, Dmitrii had my washer fixed within two hours of my initial call to them. AMAZING!! Dmitrii was very friendly and very professional. I HIGHLY recommend Trusted Appliance Repair!!!

Dmitrii provided me with quick, professional and friendly service. A part was needed to fix my washing machine and was obtained quickly with a very short turn around for the fix. All work was explained in detail and I was completely in the loop for the entire process. Very happy with the repair and service provided.

Our GE front load washer started acting up. I read some reviews of different appliance repair businesses and decided to call Trusted Appliance Repair. I call d on Monday afternoon, someone answered right away. He said a tech could be at my home same day. The tech came and quickly diagnosed the problem. Unfortunately it was a bad control board which I suspected. He said he needed to order the part and he could likely install it on Friday. But on Wednesday he called and said the part arrived and he could come over today. So it’s Wednesday afternoon about 48 hours from my call and the unit is working. The tech, Andrew, was courteous and prompt. Although I’m not happy to have to replace a board on a machine that’s only had 24 months service, I was very pleased with the service from Trusted Appliance and would recommend them. They made the entire process very easy

I have a WT7405CW LG washer. Thought I had a leaking washer unit, turns out it was the house's drain line backing up...🙃 Dmitrii figured it out quick and gave me some free advice on my dryer. Good customer service and came the next day. Would use them again 👍🏽.

Absolutely outstanding service!!! I called about a malfunctioning dryer and was offered a same-day appointment. Dmitrii was prompt, professional, friendly, and incredbily thorough. He took the time to explain everything clearly, showed me the root of the issue, and even gave me extra tips for maintaining both my dryer and washing machine. The problem is a faulty control board, which concerned me since this is a brand new machine but he reassured me that it's very common. He also gave me a lot of insight into how to handle the replacement part process with LG, and offered a very reasonable quote for labor to install the new part if they are unable to get a tech out in a timely fashion. I truly appreciated the honesty and level of care, and I cannot say enough good things about this company. If you're in the Huntersville area and need help with your appliances, you should absolutely choose Trusted Appliance Repair.

Andrey from Trusted Appliance Repair LLC did an excellent job with our oven repair in Huntersville. The oven wasn’t heating evenly, and he quickly diagnosed a faulty bake element. He replaced the part, tested the unit, and now it works perfectly again. He was on time, very professional, and the price was reasonable. If you ever need stove or oven repair in Huntersville, this is the company to call!

Expert, professional, fast service. As an automotive repair technician myself, I know first hand how it can be in the service/repair industry so professionalism and expertise is my top priority. My service technician Andrew was personable and professional, diagnosed my dryer issue within 30 minutes and performed repairs properly to a high standard. Showed me the issue I was having and was able to clearly communicate the steps to repair. Easy and fast booking with no hidden fees and clearly explained diagnosis on the invoice that was sent to me via text. This is what instills confidence to a customer that the job was done right the first time. If I could give 10 stars I would.

Incredibly great service! Definitely recommend. Dimitri came out early and was very thorough with his diagnosis and even helped me after the fact to prove to GE that I needed a replacement fridge.

faq

Sub-Zero appliance repair FAQ

Why is my Sub-Zero refrigerator not cooling?
Sub-Zero cooling loss is often caused by evaporator coil corrosion, fan failure, refrigerant leaks, or blocked airflow due to ice buildup. Because Sub-Zero systems use dual refrigeration, a single failing component can affect overall temperature balance.
Why does my Sub-Zero fridge run constantly?
This usually means the condenser is dirty, a door gasket is leaking air, or a sensor is failing to read temperature correctly. In some cases, the unit is trying to compensate for a deeper problem such as a refrigerant leak or weak compressor.
Why is my Sub-Zero freezer warm?
A warm Sub-Zero freezer is commonly caused by a damaged evaporator coil, failed fan motor, frost buildup, or a sealed system issue. If the evaporator is iced over or the refrigerant level drops, the freezer loses temperature quickly.
Why is my Sub-Zero refrigerator icing up?
Ice buildup happens when warm air enters through worn gaskets, when the defrost system fails, or when the evaporator has corrosion. Older Sub-Zero models are especially prone to this issue due to evaporator design.
Is Sub-Zero repair expensive?
Repairs can be higher than standard brands because Sub-Zero uses premium sealed-system components and specialized parts. However, repairing a Sub-Zero unit is almost always cheaper than replacing it — especially built-ins and Pro Series models.
How long do Sub-Zero appliances last?
With proper repair and maintenance, Sub-Zero refrigerators often last 20–30 years. Many breakdowns occur due to aging components, but they are fully restorable with the right repair methods.
Do you repair older Sub-Zero models?
Yes. We service all generations, including units from the early 2000s that often experience evaporator corrosion or fan failures. We can source compatible replacement parts even for discontinued models.
Do you provide same-day Sub-Zero refrigerator repair near me?
Yes. We offer same-day and next-day Sub-Zero repair in all Charlotte areas. Because cooling issues require urgent attention, we prioritize Sub-Zero appointments to prevent food spoilage and further system damage.
