Quick Checks Before Calling

If your refrigerator is not cooling properly, try these steps first:

1. Temperature Settings

Check that the thermostat was not accidentally adjusted

Recommended settings: Refrigerator 37-40F, Freezer 0F

Some models have unusual control layouts

2. Power Supply

Is the light on when you open the door?

Check if the outlet has power (plug in something else)

Check the circuit breaker

Look for a tripped GFCI outlet nearby

3. Condenser Coils

Dusty coils reduce efficiency dramatically

Located behind front grille (bottom) on most Sub-Zero units

Clean with vacuum and brush

4. Door Seals

Inspect for cracks, tears, or gaps

Clean seals with mild soap and water

Test: Close door on paper; it should resist pulling out

5. Air Circulation

Do not overfill the refrigerator

Allow space between items

Do not block air vents inside the unit

6. Clearance

Ensure adequate space around the unit

Built-ins need proper ventilation

Check that vents are not blocked
