ASKO Wine Cabinet Code T3: Zone A Evaporator Sensor Problem

Medium · inspection needed

Code: T3
Appliance: Wine Cabinet
Brand: ASKO
Warranty: 30-day workmanship

What T3 means

T3 is the temperature sensor error for the zone A evaporator on the ASKO wine climate cabinet model WCN311942G. The evaporator is the cold surface that chills the air for zone A, and its sensor tells the control how the cooling is going. When the touch display shows T3, the control cannot use that reading. Zone A may cool unevenly. The same characters point to other things on an ASKO washer or dryer; this page is for the wine cabinet.

Common causes of T3

The zone A evaporator sensor
Its wiring and connector
Frost or ice build-up around the evaporator
The control reading the sensor

✓ One safe check you can try

1. Tap X or Confirm to dismiss the message. 2. Check whether the door is closing fully, since air leaks can frost the cooling surface. 3. Avoid blocking the airflow in zone A with tightly packed bottles. 4. As the owner's manual notes, a pop-up that reappears in 3 hours means a visit is due.

! Why to stop there

The code does not show whether the sensor or the cooling around it is the issue.
We test the sensor, look at the cooling behavior in zone A, and check the door seal.
Price is written first, and the repair comes with a 30-day workmanship warranty.

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.

T3T3 questions

What is an evaporator?

It is the cold part of the cooling system inside the cabinet. Air passes over it and carries the cold into the zone, so its sensor matters to zone A.

Can ice cause T3?

Frost on the cooling surface can disturb the sensor reading. We check for it along with the sensor itself, because what we do next depends on what we find at the evaporator.

Does T3 affect zones B and C?

Each zone has its own sensors, so T3 points at zone A only. We still look over the whole cabinet during the visit, since the zones share one cooling system.
