What EC 11 means

On Sub-Zero 400 Series wine storage with the 400-2 control, such as the 424 or 430, EC 11 is the upper cabinet cold temperature alarm. The control has found the upper section colder than it should be for the setting. You see EC 11 on the display, and bottles in the upper cabinet may feel colder than expected, while the lower section can be normal. On these units EC 13 is the matching alarm for the lower cabinet.

Common causes of EC 11

  • An upper cabinet temperature setting lower than intended
  • Cooling that keeps running for the upper cabinet past its setting
  • A temperature sensor in the upper cabinet reading inaccurately
  • A control that is not regulating the upper zone
✓ One safe check you can try

1. Confirm the upper cabinet setting is where you want it. 2. Check that the upper vents are not crowded by bottles. 3. Let the unit run for a few hours after any setting change. 4. If EC 11 stays, power down at the breaker for a minute, restore it, and call us if it returns.

! Why to stop there
  • Checking the upper sensor and control needs a meter
  • Over-cooling can stem from parts behind interior panels
  • A cold zone that does not respond to settings needs proper diagnosis
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

EC 11EC 11 questions
What does EC 11 mean on my 427?

It is the upper cabinet cold temperature alarm. The control has detected the upper section running colder than its setting allows, and it alerts you so bottles do not get too cold.

How is EC 11 different from EC 13?

EC 11 concerns the upper cabinet, and EC 13 the lower cabinet. Both mean that section is too cold, so the checks are similar but focus on different zones.

What will a technician check?

We review the setting, the upper cabinet sensor and the control that runs that zone. We quote in writing before any repair, and our workmanship carries a 30-day warranty.
