--- title: "Wine cellar has drifted" description: "JennAir wine cellar has drifted: a cabinet a few degrees off, one zone right and the other wrong, or a cellar that has started to hum differently." url: "https://jennairmiami.support/symptoms/wine-cellar-not-cooling/" date_modified: "2026-08-24" Appliance type: "Wine cellars" --- # JennAir wine cellar has drifted ### The fastest diagnosis is the code Look at the grille at the bottom of the cabinet before anything else. Every undercounter cellar breathes through it, and a beautiful cabinetry run built afterwards — or a kick panel fitted flush — is the commonest reason one of these underperforms with nothing broken. Then put an independent thermometer in each zone, because the display is the thing being tested. ### The appliance that does not tell you Everything else in a kitchen announces a problem. A wine cabinet drifts: it holds a temperature two or three degrees away from the one on its display, or the right temperature at the wrong humidity, and it does that quietly for as long as nobody measures it. That is why this page starts with a thermometer and a grille rather than with a part. ### The free answer, and why it is so common here Undercounter cabinets breathe through a grille at the bottom. In a kitchen where the cabinetry was finished after the appliances went in — which is most luxury kitchens — that grille is regularly closed up by a kick panel fitted flush, or a run built tight around it. The cabinet then works exactly as designed in a space that was not. Uncovering it is sometimes the entire repair. ### Zones do half the diagnosis Most of the cellars on this make are dual-zone. One zone wrong while the other holds rules out the compressor, the condenser and the refrigerant in a single observation, and points at that zone’s fan, damper or sensor — all ordinary parts. It is why these visits are usually shorter than owners expect. A blocked toe-kick grille Free to fix and a genuinely frequent answer on a built-in cabinet. A condenser that needs cleaning Same cause, same symptom, and the same visit. A zone fan or damper One zone wrong and the other perfect is this. It also rules out the compressor immediately. A sensor reading wrong What "the display says one thing and the bottles say another" means. A door not sealing On a glass or a paneled door, as often the hardware as the gasket. Clear the grille and look behind the kick panel If it is covered, uncovering it may be the whole repair. An independent thermometer in each zone Left overnight. A display disagreeing with reality is itself a diagnosis. One zone or both One wrong points at that zone's fan, damper or sensor. Both wrong is a different search. A new hum or a vibration through the racks is a mechanical answer waiting to be found, and it is the one thing you can detect before an instrument can. Then book it Model number, single or dual zone, which zone, and the measured temperature against the displayed one. Two degrees is worth calling about What it usually means One zone holding and the other not A display and a thermometer disagreeing A new noise or vibration through the racks The fastest diagnosis is the code Look at the grille at the bottom of the cabinet before anything else.

A refrigerator two degrees off is an inconvenience; a cellar two degrees off held for months is a measurable change to what is in it. And two degrees is early — it is the symptom that arrives before the one that would have made you call anyway. ### What do E1 and E2 mean on an undercounter cabinet? They are the sensor codes on this maker's undercounter refrigeration, including the wine cellars and beverage centers — the cabinet reporting that a temperature sensor is out of range rather than that the cooling has failed. Which one it is names which sensor, and both are ordinary repairs. ### Why does humidity matter? Because it shows on corks and labels long before it shows anywhere else, and because no panel on any of these cabinets reports it. It is measured on the visit rather than asked about. ### The house is empty half the year. Then this is worth a look before the season rather than after it. A cellar that drifts in March is discovered in November. If the cabinet is on a smart connection, it is worth having the alerts reach somebody who reads them. --- **[Read full article: Wine cellar has drifted](https://jennairmiami.support/symptoms/wine-cellar-not-cooling/)**
