Sub-Zero Designer Wine (IW) Code 10 2 00: zone 2 air thermistor open

What 10 2 00 means

On Designer Wine (IW) units such as the IW-30 and IW-30CI, 10 2 00 means the zone 2 cabinet thermistor is open. The air sensor that tracks zone 2 shows no circuit, so the control cannot measure that zone's air. It switches to fallback cooling for zone 2. Expect bottles there to end up warmer or colder than intended, and the zone 2 display may show dashes or a value that never moves.

Common causes of 10 2 00

A zone 2 air sensor plug that came apart
A broken lead in the zone 2 wall
An open zone 2 cabinet thermistor
A control board that has lost the zone 2 input

✓ One safe check you can try

1. Check zone 2 with a thermometer on a middle shelf. 2. Confirm the zone 2 door seals. 3. Keep the sensor area clear. 4. Turn off the breaker for a minute, then restore it. 5. Call us if 10 2 00 stays on.

! Why to stop there

The lead runs inside the wall behind the liner
An open circuit has to be located with a meter
The control board is on line voltage

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.

10 2 0010 2 00 questions

Is 10 2 00 related to 10 2 10?

They share zone 2 but are different sensors. 10 2 00 is the cabinet air sensor; 10 2 10 is the evaporator coil sensor. We test each separately.

Will zone 2 still cool?

It will cool on a fallback routine, but not precisely. Check with a thermometer and move your best bottles if zone 2 drifts far from its set point.

Is the repair covered?

Yes. After testing and a written price, our repair carries a 30-day workmanship warranty. Most zone 2 air sensor jobs on the IW-30 are finished in a single visit once the plug, lead and thermistor are tested.
