This comprehensive guide is your lifeline when your prized appliance suddenly refuses to cooperate. Whether it’s a minor glitch or a major malfunction, we’ll walk you through potential causes and offer practical solutions. Our expert advice will empower you to diagnose the problem and get your Sub Zero fridge not turning on to running optimally again in no time.
1. Power Supply Issues
Checking the Power Cord and Outlet
One of the first steps is to ensure the power supply to the refrigerator is intact. Follow these steps:
- Inspect the Power Cord: Ensure the power cord is firmly plugged into the outlet. Check for any visible damage to the cord.
- Test the Outlet: Use a multimeter to test the power outlet. Alternatively, plug another appliance into the same outlet to verify if it’s functioning.
Resetting the Circuit Breaker
Sometimes, a tripped circuit breaker can make the Sub Zero freezer not working as it should. Here’s how to check:
- Locate the Circuit Breaker Box: Usually found in basements, garages, or utility rooms.
- Check for Tripped Breakers: Look for any switches that are in the “off” position or in between “on” and “off.” Reset them by turning them off and then back on.
2. Thermostat and Control Board Issues
Inspecting the Thermostat Settings
The thermostat settings could be incorrectly adjusted. Here’s what to do:
- Locate the Thermostat: Typically found inside the refrigerator.
- Check the Settings: Ensure it is set to the desired temperature. Adjust if necessary and wait to see if the refrigerator turns on.
Testing the Control Board
The control board is crucial for the refrigerator’s operation. Follow these steps to test it:
- Access the Control Board: Refer to the user manual for the location, usually at the back or top of the refrigerator.
- Visual Inspection: Look for any signs of damage or burn marks.
- Test with a Multimeter: Check for continuity in the control board circuits. Replace the board if it’s defective.
3. Compressor and Relay Problems
Evaluating the Compressor
The compressor is the heart of the refrigerator. Here’s how to evaluate it:
- Locate the Compressor: Found at the back bottom of the refrigerator.
- Listen for Noises: A functioning compressor should produce a low humming sound.
- Test with a Multimeter: Check the electrical terminals for continuity. A lack of continuity indicates a faulty compressor.
Inspecting the Start Relay
A faulty start relay can also be a common reason for your Sub Zero freezer not working. Inspect it by:
- Locating the Relay: Attached to the side of the compressor.
- Shake Test: Remove the relay and shake it gently. If it rattles, it’s likely defective and needs replacement.
4. Door Switch and Internal Lights
Checking the Door Switch
The door switch turns off the lights and fan when the door is closed. Here’s how to check it:
- Locate the Switch: Usually found around the perimeter of the refrigerator door.
- Test the Switch: Press and release it. If the internal light doesn’t turn off and on, the switch may be defective.
Replacing the Internal Light Bulb
Sometimes, a burnt-out light bulb can indicate an issue. Here’s what to do:
- Access the Bulb: Typically found inside the refrigerator, near the top.
- Replace the Bulb: Use a bulb with the same wattage and type as the original.
