The Monogram lineup
Monogram model numbers nearly all begin with the letter Z — the family signature — and once you can read the rest of the string you can identify the technology inside, the configuration, and the parts a repair will need. The second letter names the family: I for refrigeration and ice, G or H or E for cooking surfaces, T for ovens, D for dishwashers and drawers, S for speed ovens, V for ventilation, and W for wine and drawer units. The suffix encodes finish — SS for stainless, BB for black, II for integrated or panel-ready. Browse the families from the appliances overview or jump into the model library.
Cooking model families
Ranges use ZDP for dual-fuel (ZDP364NDPSS, ZDP486NDPSS) and ZGP for all-gas pro (ZGP304NRSS). Cooktops split by fuel: ZGU gas (ZGU385LSMSS), ZHU induction with Glide Touch (ZHU36RSJSS), and ZEU electric (ZEU36RBFBB). Wall ovens carry ZET for single and convection units (ZET1SMSS, ZET2PLSS) and ZTD for Statement double and warming ovens (ZTD90DPSNSS). Speed ovens use ZSB for the Advantium (ZSB9132VSS) and ZWL for the drawer microwave (ZWL1126SJSS). Service starts at range repair.
Refrigeration model families
Built-in refrigerators use ZIS for side-by-side units (ZISS420DNSS, ZISS42NCSS) and ZWE for French-door built-ins (ZWE23NSYSS). Column refrigeration breaks into ZIR refrigerator columns (ZIR240NPKII, ZIR301NPNII), ZIF freezer columns (ZIF240NPKII, ZIF361NPRII), and ZIC panel-ready bottom-freezers (ZIC30GNHII). Wine reserves use ZDW (ZDWI240WII), beverage centers use ZDB (ZDBT240PBS), and ice makers use UNC / UCC for clear ice (UNC15NPRII, UCC15NJII) plus ZDIS / ZDIC for nugget and specialty units. Service begins at refrigerator repair.
Dishwashers and ventilation
Dishwashers carry the ZDT prefix (ZDT915SPJSS, ZDT985SPNSS, ZDT925SINII), with the suffix telling you the finish and whether the unit is fully integrated and panel-ready (II) or a stainless front (SS). Ventilation hoods use the short ZV prefix (ZV800SJSS, ZV950SDSS). Because these install into a precise opening, the model number tells a technician the width, the configuration, and which panel and mounting hardware the job involves before arrival.
Collections and the suffix letters
Beyond the family prefix, a Monogram model belongs to one of four design collections that shape how it installs and what hardware it carries. Statement units wear bold edge-to-edge handles, stainless with solid brass accents, and LCD displays; Minimalist units install flush with push or tap-to-open and minimal hardware; Designer units take custom Brass and Titanium finishes with floor-to-ceiling panels; and Professional units bring commercial-inspired capacity to ranges and rangetops. The suffix letters that look like a typo actually encode finish and feature options, which is why a technician needs the complete model string rather than just the prefix — two units with the same ZIS or ZDT prefix can take different handles, panels, or drawer assemblies.
Decoding and servicing your model
A Monogram model number combines the Z family prefix, a family letter, a configuration number, and a finish suffix — reading all of it identifies the exact build. The rating plate is usually on an interior side wall, behind a drawer, or along the door jamb; record the full string before you book. If your appliance is showing a fault, start with the error-code and fault library, then match the family above. Our certified technicians service every Monogram family regardless of age, using genuine parts matched to the build, and specifications can be confirmed on the manufacturer’s site at monogram.com. When you have your model in hand, schedule a repair — diagnostic visits start from $129, with the final cost depending on parts and configuration.
