How we fix your under the counter wine coolers.

It seems like everyone has a beloved 424 wine cooler in their home. This wine cooler was produced by Sub-Zero for at least 20 years and they pretty much can always be repaired if you have a sharp technician. It is best to repair these for a variety of reasons, this being:

  1. Cost
  2. Cabinetry Dimensions
  3. This unit has an excellent, simple build quality.
  4. Good availability of parts from the Sub-Zero Parts distributor.
  5. Quick turn around

Wine Coolers operate at higher temperatures and humidity.

Wine Coolers are wet system, they produce a lot more moisture than a refrigerator or freezer. This moisture has a way of corroding the parts that make the machine cold. We see in increase in sealed systems issues because of this. We see it not just in Sub-Zero brand wine coolers, but across the board.

The Most Common Wine Cooler repair is...

Replacing components of the sealed system such as:

  • Evaporator Coils
  • Heat Exchangers
  • Gas Solenoid Valves
  • Inline Filter Driers

The parts are upgraded during this repair.

The old components were made of copper, now they are made of "leak proof" aluminum. When we convert these machines to the new style aluminum coils we get a much more reliable system going forward.
