Sub-Zero Not Cooling in Sunnyvale?
This is the most critical appliance failure. A warm Sub-Zero puts your health and hundreds of dollars in food at risk. Our emergency technicians are on standby 24/7 to provide an immediate solution.
The Most Urgent Appliance Emergency
There is no more stressful appliance issue than a refrigerator or freezer that has stopped cooling. The clock is ticking on food spoilage. At Sub-Zero Repair Prime, we treat "not cooling" calls with the highest priority. Our Sunnyvale-based technicians are dispatched immediately to diagnose the problem and restore your appliance's function, often on the very same day.
Top 5 Reasons Your Sub-Zero Isn't Cooling
While a full diagnosis is always necessary, here are the most common culprits we find during our service calls in the Sunnyvale area:
- Dirty Condenser Coils: Dust and pet hair can clog the coils, preventing the unit from dissipating heat. This is the #1 cause of cooling failure and is preventable with regular maintenance.
- Faulty Evaporator Fan Motor: This fan circulates cold air within the freezer/refrigerator. If it fails, the cooling coils may frost over and stop the flow of cold air entirely.
- Compressor or Start Relay Failure: The compressor is the heart of the cooling system. If it or its starting components fail, the refrigeration cycle stops completely.
- Thermostat or Sensor Malfunction: If the unit's "brain" doesn't know it's warm, it won't tell the compressor to turn on. We can test and replace these sensitive parts.
- Sealed System Refrigerant Leak: While less common, a leak in the sealed system will lead to a gradual or sudden loss of cooling power. This is a complex repair that requires a specialist.
When to Call for Immediate Help
Do not delay if you notice any of the following:
- The temperature inside the fridge is above 40°F.
- You hear the compressor clicking on and off repeatedly.
- There is no sound coming from the appliance at all when it should be running.
- You find a puddle of water that seems to have come from the unit.
These are signs of a serious issue that requires immediate professional attention. Call our 24/7 Sunnyvale emergency line right away.

Frequently Asked Questions
Your questions, answered by our Sunnyvale experts.
My Sub-Zero is running, but not cooling. What's the first thing to check?
First, check that the temperature settings haven't been changed accidentally. Also, ensure the door is fully closed and the condenser coils (usually at the top) are not caked with dust. If these simple checks don't solve it, call us immediately for a professional diagnosis.
Is it safe to keep food in a Sub-Zero that is not cooling properly?
No. For food safety, refrigerators should be kept at or below 40°F (4°C). If your unit is warm, transfer perishable items to a cooler with ice. We offer 24/7 emergency service in Sunnyvale to address these urgent situations.
Could a power surge in Sunnyvale cause my Sub-Zero to stop cooling?
Yes, power fluctuations can damage sensitive electronic components like the control board or overload the compressor's relay. If your unit stopped cooling after a storm or power outage, it's a strong possibility that an electrical component has failed.
