Sub-Zero Legacy Classic Series (BI) Wrench Icon Flashing and Alarm Chiming


  • Service icon flashing and alarm chiming
  • Elevated temperatures in unit with wrench flashing and alarm chiming
  • Classic Series (BI) model beeping with the wrench flashing
  • Wrench is blinking on the control panel on a Classic that is chiming
  • Alarm chiming with door shut


  • Major error code logged


If a wrench icon appears and the alarm is chiming:

  • If there are any temperature or performance issues, troubleshoot these issues separately. 
  • If there are no temperature or performance issues:
    1. Turn the home circuit breaker to the unit off for 30 seconds then back on again.
    2. Monitor unit operation.

If these troubleshooting steps do not resolve the issue, service is necessary to expertly diagnose and repair the product. Contact Factory Certified Service to schedule an appointment for repair.
