Sub-Zero Designer Wine (IW) Code 35-C-00: DC condenser fan open

What 35-C-00 means

Sub-Zero Designer Wine (IW) units such as the IW-30 and IW-18 show 35-C-00 when the DC condenser fan reads as open. This fan cools the condenser by drawing room air across it. With the circuit open, the control sees no fan, heat stays around the condenser, and cooling slows across the unit. The display shows 35 C 00. The compressor also runs hotter than it should.

Common causes of 35-C-00

An open DC condenser fan motor
A broken connection in the condenser fan wiring
A control board output not reaching the fan

✓ One safe check you can try

1. Clear the grille and keep the area in front of it open. 2. Listen at the grille for fan noise while the compressor runs. 3. Restart the unit at the breaker once. 4. Call us if 35-C-00 remains. 5. Do not cover the grille with a rug or toe-kick panel while you wait.

! Why to stop there

The condenser fan is behind the grille and access panels
Fan and wiring checks need a meter
Running without condenser airflow stresses the compressor

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.

35-C-0035-C-00 questions

How is 35-C-00 different from 15-C-00?

35-C-00 says the DC condenser fan circuit itself is open. 15-C-00 points to the relay for the AC condenser fan stuck open. Both leave the condenser without airflow, but the part involved differs.

Can dust cause this code?

Dust on the condenser does not open the fan circuit, but cleaning the grille area still helps the unit while you wait for service. Vacuum the grille face gently without removing panels.

Will you replace the fan?

If testing shows the fan is open, yes. If the wiring or board is the cause, we repair that instead. You get a written price first and a 30-day workmanship warranty.
