If a Sub-Zero refrigerator is running but not cooling well, the problem is often the evaporator. This part is located behind the rear panel and is responsible for making cold air. Over time, the metal can wear out and a refrigerant leak can start. We recently repaired a compact Sub-Zero 700BR2 refrigerator in a home located in Rancho Santa Fe. The refrigerator was running, but the temperature inside was too warm. Our diagnosis showed a leak in the evaporator coil. It is important to understand that problems like refrigerant leaks happen slowly, not all at once. At first, the refrigerator starts running longer than normal. The air coming from the compressor feels very warm. Later, the unit may hardly turn off at all. Over time, the temperature inside keeps getting warmer and warmer until the refrigerator can no longer cool properly. Finding this problem early is very important. If a refrigerator keeps running with a leak, the compressor can become overloaded and fail. When that happens, the repair becomes much more expensive and may require a full system rebuild. During this repair, we replaced the evaporator coil, the suction line with the capillary tube, and the filter drier. The system was fully flushed, vacuumed, and recharged with refrigerant. The compressor was also checked for proper operating pressure. All work was done according to Sub-Zero factory standards. After the repair, the refrigerator returned to normal and stable cooling. Sub-Zero refrigerators are built to last, but over time even high-quality parts can wear out. In compact models like the 700BR2, an evaporator problem can affect the entire refrigerator. Things to watch for: The refrigerator runs longer than it used to Cooling takes more time than before The compressor rarely turns off The refrigerator does not feel the same as it used to If you own a Sub-Zero refrigerator or any other brand, do not ignore small changes. Small problems can turn into big and expensive repairs. If you have any questions or notice changes in how your refrigerator is working, feel free to call Big Joe Appliance Repair to schedule a diagnostic visit. We will be happy to help. We service Sub-Zero refrigerators throughout San Diego and San Diego County, including Rancho Santa Fe, Rancho Peñasquitos, La Jolla, Del Mar, and Cardiff, Rancho Bernardo, Solana Beach, San Elijo.

If your Sub-Zero freezer is no longer freezing properly, even though the compressor and fan are running, the issue is often a leaking or corroded evaporator coil. We recently helped a homeowner in La Jolla who experienced a slow refrigerant leak from the evaporator coil located behind the rear panel. This is a common problem in older Sub-Zero 500 and 600 Series units, especially after 10+ years of use. We replaced the evaporator coil with a genuine OEM part, performed a full vacuum and refrigerant recharge, and cleaned the condenser. The freezer was fully restored to proper operation in a single visit. Sub-Zero units are built to last, but over time the evaporator coil can corrode and develop small leaks. In dual-compressor models, this failure may affect only the freezer compartment. Common signs of evaporator failure include: • Freezer not maintaining temperature • Ice buildup behind the panel • Short cycling or clicking sounds • Food thawing We provide full diagnostics, sealed system repairs, and preventive maintenance for Sub-Zero freezers throughout San Diego, Rancho Penasquitos, Rancho Bernardo, and La Jolla, using factory-grade OEM parts.

Today a customer contacted our team and complained about bad cooling of their built-in refrigerator Sub Zero. We were glad to take the order. Our experienced technician visited the client as soon as he could. It is usually difficult to quickly find the root cause of such an issue. Many reasons could lead to the problem as the internal system producing cold consists of several parts. A thorough search showed that there was a leakage of refrigerant in the fridge. Further diagnostics made it visible that refrigerant leaked through the service valve. The bad part was successfully and accurately replaced. After the replacement of the valve, the refrigerator was charged with new refrigerant. Now owners enjoy their built-in home appliances. We are always ready to help with home refrigeration systems.
