156 pages, zero codes
The official Dacor wine and beverage column manual for the DRW24980LAP — despite carrying “Heritage” in its own file name, an internal document-naming artifact rather than a collection claim, since the unit itself is explicitly branded a SmartThings-connected Smart wine cellar — documents the same four-alarm structure as the refrigerator and freezer lines across all 156 pages, and no alphanumeric code appears anywhere in it.
The fabricated codes to ignore
A page claiming TEMP-HI, TEMP-LO, COMP-ERR, FAN-FAIL, and PF for Dacor wine units follows the exact fabricated-code template used for the range hood on the same site, and every one of those codes is contradicted by the primary manual, which has no codes at all. Do not repeat them.
Symptom-led checks
A dual-zone unit with one zone correct and the other off-temperature points at that zone’s own sensor or its independent cooling system, since PreciseCooling holds each zone to roughly half a degree separately. Tartrate crystals forming on a white wine, or bottles reading too warm despite a correct display, both point at the sealed system rather than the display itself.
When to call
A Door Opening alarm that will not clear with the door shut, or a compressor that runs constantly, needs an experienced technician handling the sealed system under EPA Section 608 rules with the correct genuine OEM or trusted-supplier part. See the wine refrigeration diagnostics page, then book wine refrigeration repair.
