A:Answer Your refrigerator features Turbo Cool, which helps to maintain the interior temperature. The display may show tC to indicate when Turbo Cool is being used. If you're sure the display is showing ec instead, we recommend disconnecting the appliance from power for a couple of minutes before reconnecting, to reset it. If that doesn't help and you think service is needed, our Bodewell team can be reached at 1-833-426-3393. They are open Monday – Friday, 8AM – 8PM ET, and a technician would be glad to examine the refrigerator for any issues.
