Field Notes from a Wine and Undercounter Bench

   Holding the Zones

   Why a wine zone drifts, what the display leaves out, and restarting after the wind.

   1. When a Sub-Zero Wine Cooler Will Not Hold Its Zones The first note in the series: one zone warm or both, and why the two are different faults.
   2. Both Zones Warm: When a Sub-Zero Wine Unit Stops Pulling Down Both zones creeping up together: the machine bay, the air around the cabinet and the door, before the compressor.
   3. Red, White and What a Sub-Zero Wine Unit Can Actually Hold What to set each zone to, what the range allows, and when a zone that misses its number has a fault.
   4. A Wine Unit That Starts and Stops Every Few Minutes Timing the start-stop pattern, and why heat trapped at the kickplate is where we look first.
   5. The Display Says 55: Checking a Wine Unit With a Probe What the number on the panel actually means, and the twelve-hour glass-of-water check for each zone.
   6. Heat Next Door: Wine Columns Beside a Range and West Glass A cooking range, and afternoon sun, beside a wine column: what the extra heat does and what can change.
   7. After the Wind: Restarting Wine Storage When Island Power Returns Door shut while the power is out, four checks when it returns, and the signs that call for a visit.

   Lake Air

   Fog on the glass, damp labels, tired gaskets, frost on the coil and units living outdoors.

   1. Water, Frost and Ice Inside a Built-In Sub-Zero Where the meltwater stops: a drain, a defrost circuit or a door seal, told apart before anyone opens the cabinet.
   2. Condensation on a Sub-Zero Wine Door: Reading Where the Water Forms Mist on the room side, haze on the cabinet side, beads on the bottles: which side of the glass the water is on, and why that matters.
   3. Damp Labels and Mold Inside Wine Storage Soft labels, spotted capsules and a musty smell: how damp gets into a wine cabinet, how to clean it out, and when it keeps returning.
   4. How a Glass-Door Gasket Fails, and What It Does to the Zones Hardened, flattened, split or lifted at a corner: how the seal on a wine door gives out, and what each zone does about it.
   5. Afternoon Sun on a West-Shore Kitchen and the Wine Unit in It What UV-resistant glass keeps from the wine, what it lets through, and how to tell sunlight from a failing part.
   6. Frost Where There Should Be None: The Wine Evaporator White on the back wall of a wine zone: why it forms, how to melt it without damage, and which part it points to.
   7. Docks, Decks and Boathouses: Undercounter Units Outside the Heated House Undercounter units on decks, docks and in boathouses: which are built for it, what lake weather does, and the off-season.

   Under the Counter

   Undercounter refrigerators, beverage centers and drawers — small machines with little air.

   1. A Sub-Zero Undercounter Refrigerator That Has Stopped Cooling Power, the panel, the coil behind the kickplate and the door, taken in that order before anyone reaches for gauges.
   2. Beverage Center Too Warm, or Freezing the Cans at the Back Warm cans and frozen cans from one cabinet: the condenser, the door, the way it is packed and the set point.
   3. Refrigerator Drawers That No Longer Pull Themselves Shut A drawer that stops a finger short: what is behind it, how the slides are running and what the gasket looks like.
   4. The Toe-Kick Is the Lung: Ventilation on Undercounter Units Why an undercounter unit breathes at floor level, and the remodel details that quietly choke it.
   5. A Quiet Room and a Noisy Undercounter Unit Which hums, clicks and gurgles a Sub-Zero makes by design, and which new sounds are worth a visit.
   6. Bar and Butler’s-Pantry Units: What Tends to Fail First Party loads, a busy door and a warm room: the coil, the seal, the lights and the ice maker, in roughly that order.

   One Bridge

   The phone call, the parts wait, a long absence, a remodel and two units on one trip.

   1. No Second Route: Diagnosing a Sub-Zero Right the First Time When I-90 Is the Only Way On and Off Why an island job is worked all the way to the fault on the first visit, told through the ice maker.
   2. Model, Serial, Symptom: What to Have Ready Before You Call Three things to have in front of you when you ring, and where on the unit to find them.
   3. Protecting a Collection While the Unit Is Down What to do with the bottles from the first hour of a fault until the repaired unit is holding again.
   4. Away for the Season: Settings for Wine and Undercounter Units What Sub-Zero tells owners to do before a long trip, and why a cabinet full of wine is a different case.
   5. Pulling and Resetting an Undercounter Unit During a Remodel What to settle with the contractor before an undercounter unit comes out, and what to check once it is back.
   6. Waiting on a Part: What Happens Between the Two Visits Why a part is sometimes ordered rather than carried, and what the unit, you and we do until it arrives.
   7. Two Units, One Trip: Having the Wine Unit and the Main Refrigerator Seen Together Two Sub-Zero appliances on one service call: why the second unit is worth mentioning when you book, and how the visit is run.
