Sub-Zero Designer Wine (IW) Code 10 C 01: condenser sensor shorted

What 10 C 01 means

On IW-30 and IW-18 units from the Designer Wine (IW) line, 10 C 01 means the condenser thermistor is shorted. The sensor in the condenser area reads a resistance so low that no real temperature could explain it. The control drops the reading and runs condenser management on defaults. Owners may not notice much at first, though the unit may run louder or longer when the kitchen is warm.

Common causes of 10 C 01

A lead rubbing on a metal edge in the machine compartment
Moisture or grime in the sensor plug
A condenser thermistor shorted inside
A control that misreads the circuit

✓ One safe check you can try

1. Brush lint from the grille. 2. Keep the area in front of the grille open. 3. Note whether the unit sounds louder than usual. 4. Power-cycle once at the breaker. 5. Book a visit if 10 C 01 comes back.

! Why to stop there

The compartment holds the compressor and fan on live circuits
Locating a short takes meter testing
Hot surfaces in the compartment can burn

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 C 0110 C 01 questions

Why is my IW-30 running louder?

With the condenser reading lost, the control may run the condenser fan on a default speed. That can sound louder than the quiet, adjusted speed you are used to.

Does dust cause 10 C 01?

Dust alone does not short a sensor, but dirt and moisture in the plug can. Keeping the grille clean helps the system either way. Brush it every few months.

How do you fix it?

We trace the lead, check the plug and test the thermistor, then give a written price. Repairs carry a 30-day workmanship warranty. We also clean the condenser while there.
