The letters at the front name the family
A Monogram model number is a product line, not a serial. Z is Monogram. The second letter names
the family — I for refrigeration and ice, G for gas, H for induction, D for a dishwasher or a drawer,
S for a speed oven, T for an oven, V for ventilation, W for wine or warming, E for the hearth oven.
The suffix is the finish: SS is stainless, BB is black, II is integrated or panel-ready. So ZDP is a
dual-fuel professional range and ZGP is the all-gas version of the same appliance, and the one letter
between them decides whether the oven has an element or a burner.
Why every page here names its siblings
Appliances that share a prefix share their engineering and differ in width, finish and hinge,
which means they share their parts and their failures too. Publishing one page per SKU would be
forty-six pages saying the same thing about a hundred and two appliances. Publishing one page per
family, with every sibling number listed on it, means a number that is not the one at the top of the
page still lands somewhere useful — and it means the page can say something true about the whole
line rather than something generic about one of them.
Where the number actually is
On refrigeration it is inside the fresh-food compartment, usually on the left wall. On a fully
integrated dishwasher it is on the tub edge behind the door. On a range or a wall oven it is on the
frame behind the door, and on some ranges behind the bottom drawer. Photograph it rather than
copying it down: these numbers are long, and one wrong character sends a technician to the wrong
parts list.
Why this list is the current catalog and nothing else
Every number on these pages was taken from the manufacturer’s own storefront and resolves to a
live product page there. That makes this a shorter list than an old parts index would produce, and a
correct one — a good deal of what earlier write-ups of this brand list has simply stopped being
sold. If your number is not here, that says nothing about whether we repair the appliance. Send the
whole number off the plate and what it is doing, and we will tell you which family it belongs to and
what the visit would involve.
