T18IW900SP

Thermador T18IW900SP

What we most often repair on units like this

  1. Temperature drifting from the wine setpoint
  2. Cooling fan noise or vibration against bottles
  3. Presenter lighting out
  4. Door not closing softly or gasket gap
  5. Condensation between glass panels

At 17 3/4 inches wide and almost seven feet tall, the T18IW900SP is a wine column built into a cabinet wall, usually in a dining room, butler pantry or bar area. It holds 58 standard bottles on 10 shelves, so a cooling interruption puts a real collection at risk.

For a unit this tall, we look at temperature stability top to bottom, since a weak fan or a leaking door gasket creates warm spots on the upper shelves. Vibration is the other concern: loose shelf rails or a rattling fan can disturb sediment. We also test the presenter lighting and the SoftClose action.

Because wine is sensitive to heat, we give the temperature log a close look and explain what we measure before any parts are ordered.

The T18IW905SP is listed as the successor. Our visit includes a written price in advance and a 30-day workmanship warranty.

T18IW900SPT18IW900SP questions
Can you tell if my T18IW900SP is holding temperature evenly?

Yes. We place probes at several shelf heights and compare them with the setpoint, which shows whether a weak fan or a leaking seal is the cause of any drift.

The presenter shelf light is off. Is that a big repair?

Usually not. We check the lamp, wiring and door switch before quoting anything, since the presenter lighting is a small circuit separate from the cooling system.

Do the two glass panels cause moisture problems?

They can fog if the door seal leaks humid air into the cabinet. We inspect the gasket, the hinge alignment and the drain path before suggesting any other fix.
