Sub-Zero Designer Wine (IW) Code 45-2-00: zone 2 lights not drawing power

What 45-2-00 means

For Sub-Zero IW Designer Wine Storage like the IW-30CI, 45-2-00 says the zone 2 lights read as an open circuit. The control powers the zone 2 lights but sees no current flowing. The zone 2 lighting stays off, cooling is not affected, and 45 2 00 is displayed. Nothing about wine temperature changes because of it, and the other zones keep their lighting as long as their own circuits are intact.

Common causes of 45-2-00

A burned-out zone 2 light
A disconnected light plug
A broken wire in the zone 2 light circuit
A board output that is not supplying power

✓ One safe check you can try

1. Check whether the zone 2 lights work when the door opens. 2. Make sure the door switch area is not blocked by a bottle. 3. Reset power one time at the breaker. 4. If zone 2 stays dark, let us know. 5. Leave the light housing alone until we can check its wiring.

! Why to stop there

Light fixtures connect to the main wiring
Some fixtures require panel removal
Board checks need the unit powered

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.

45-2-0045-2-00 questions

Is 45-2-00 urgent?

No. It affects only the zone 2 lights. You can book service at a convenient time. Cooling and wine temperatures are unaffected, so it can wait for a convenient day.

Could a bottle block the light switch?

It is worth checking that nothing presses on the door area. A blocked switch can keep lights off, though the code itself points to an open light circuit.

What is the repair?

We find the open spot in the light, plug or wiring and fix it. Pricing is given in writing first, and our workmanship carries a 30-day warranty.
