If your refrigerator or freezer is not operating properly, use the following troubleshooting guide before calling your Sub-Zero authorized service center. This guide will save you time and trouble and may help you avoid the expense of a service call.

SERVICE is illuminated in the Control Center display panel

The microprocessor has sensed a problem with the operating system. There may be instructions in the Control Center display panel to solve the problem. If not, call the Sub-Zero Customer Service Department at 800-222-7820.

SERVICE is flashing in the Control Center display panel

This may indicate that the condenser needs cleaning. Follow the Condenser Cleaning procedure outlined on page 22.

This happens when one or more of the sections runs too long. A temperature sensor may be faulty. If this occurs, turn the unit off with the UNIT ON/OFF key pad and then restart by depressing the key pad again. If SERVICE is still flashing, call the Sub-Zero Customer Service Department at 800-222-7820.

SERVICE and ICE are both flashing in the Control Center display panel

This occurs when the solenoid valve for the ice maker is activated too long. Check for excess water near the ice maker. If you see excess water, turn off the water at the shut-off valve and call for service. If there is no excess water, turn the unit off and back on to reset and see if this corrects the problem. If the problem continues, call the Sub-Zero Customer Service Department at 800-222-7820.
