Wine Storage Repair
Dual-zone wine columns and undercounter cabinets where a zone has drifted, the glass has started sweating, or the two compartments have quietly merged into one temperature.
How it gets described on the phone
- Both zones settling on the same number no matter what each one is set to
- Condensation beading on the inside of the glass door on a humid week
- A compartment several degrees above setpoint from late afternoon onwards
- Interior lighting flickering, or one zone no longer answering the control
What actually gets tested
- Each zone read at the shelf with a probe left in place, never from the control panel
- Damper, zone sensors and the board circuit driving them
- Door seal compression and the anti-condensation heater on glass doors
- Condenser air path where the cabinet is boxed into an island with no clearance
- Sealed system under gauges when a zone only runs warm from the afternoon onwards
The panel is not evidence. A probe goes on a shelf in each compartment and stays there while the rest of the diagnosis happens, because a control that has lost a zone it can no longer read will keep displaying a number that looks entirely reasonable. Damper, sensors and the door heater are then tested against the probe readings rather than against the display.

Sitting three or four degrees warm every afternoon and correcting itself overnight, so of course nobody could catch it. He data logged it for a day and then replaced exactly one part.

Glass door sweating through a humid week and I thought the seal had gone. The heater circuit in the frame had failed. He replaced it and the glass has stayed clear through this summer.

Cabinet is built into joinery with almost no gap behind it, and it had been struggling for a year. He cleaned the condenser, corrected the venting at the plinth, and it holds setpoint now.

Dispatch takes the model, the fault and the address, and books the first slot that suits the route rather than the first one on the sheet.
