STAGE 03 OF 05
PART
Finding the right component, telling a genuine part from a poor one, and knowing when a substitution is acceptable.
-
What the Model Number Actually EncodesA walk-through of how appliance and electronics model numbers are structured, what the substrings mean (production run, market variant, colour code), and how to use them to find the correct replacement part rather than a close one.
-
Same Part, Lower Price — When the Substitution HoldsA comparison piece examining door seals, drive belts and pump impellers across OEM and aftermarket supply, identifying where material specification matters and where it does not, with criteria the reader can apply themselves.
-
The Patch That Doesn't MatchA practical argument that a visible repair is not a failed repair — covers fabric sourcing for darning and patching, explains why matching is structurally irrelevant for most mends, and describes how to find appropriate weight and weave without specialist shops.
-
Dead Stock: Finding Parts for Things That Are No Longer MadeA systematic method for sourcing components for discontinued products — donor machines, industrial surplus, 3D-print services, specialist dismantlers — structured as a sequence of escalating effort.
