What 10-3-00 means

Zone 3 on a Designer Wine (IW) unit such as the IW-30CI has its own air sensor, and 10 3 00 means that zone 3 cabinet thermistor is open. The control is seeing no circuit, so it has no reading of the air temperature in zone 3. It falls back to a rough cooling pattern. Expect zone 3 to drift above or below its set point and the zone display to show dashes or an unrealistic value.

Common causes of 10-3-00

  • A disconnected zone 3 sensor plug
  • A broken wire behind the zone 3 liner
  • An open zone 3 cabinet thermistor
  • A control input that cannot read the sensor
✓ One safe check you can try

1. Put a thermometer in zone 3 and check it after an hour. 2. Make sure the zone 3 door shuts fully. 3. Keep items away from the zone 3 sensor area. 4. Turn the breaker off for a minute, then on. 5. If 10 3 00 stays, call us.

! Why to stop there
  • Wiring behind the liner is reached only through panels
  • An open circuit needs a meter to locate
  • The control board sits on live 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.

10-3-0010-3-00 questions
What does an open zone 3 sensor mean in practice?

The control has no air reading for zone 3. It keeps cooling on a fallback schedule, so the zone may be too warm or too cold until the sensor circuit is repaired.

Could a loose plug cause 10-3-00?

Yes, a plug that slipped off during a panel removal or move is a common cause. We check connections before replacing the thermistor. Moving an integrated unit can tug the lead.

What does the visit include?

Testing of plug, wire and sensor, then a written price. Approved repairs carry our 30-day workmanship warranty. For an IW-30CI, the zone 3 sensor sits behind the liner, so the visit also includes careful panel removal and refit.
