Sub-Zero 400 Series Wine Code EC 13: lower cabinet cold alarm

What EC 13 means

Sub-Zero 400 Series wine storage units built with the 400-2 control, the 427 and 424 for example, show EC 13 as the lower cabinet cold temperature alarm. The lower section has dropped below the temperature its setting calls for. The display reads EC 13, and wine in the lower cabinet can feel noticeably chillier, while the upper part may be fine. EC 11 is the twin alarm for the upper cabinet.

Common causes of EC 13

A lower cabinet setting that is lower than intended
Cooling to the lower cabinet continuing past its setting
An inaccurate lower cabinet temperature sensor
A control not regulating the lower zone properly

✓ One safe check you can try

1. Double-check the lower cabinet temperature setting. 2. Move bottles that block the lower air openings. 3. Allow some hours for the zone to settle after a change. 4. If EC 13 persists, do one breaker reset and book us if it comes back.

! Why to stop there

The lower sensor and control are tested with a meter
Parts behind panels carry live voltage
A zone that ignores its setting needs a technician

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 13EC 13 questions

Is EC 13 dangerous for my wine?

Overly cold storage is not ideal, and very low temperatures can push corks. Check the setting first, and if the alarm stays, have it looked at soon.

Why only the lower section?

The 400-2 control watches upper and lower cabinets separately. EC 13 tells you the lower one is too cold; the upper can still be normal.

How do you repair EC 13?

We verify the setting, test the lower cabinet sensor and check the control output. You approve a written price first, and our work is covered for 30 days.
