Take a Picture: Once you locate your model label, take a picture of it to reference it later when researching replacement parts.
Watch for Ambiguous Letter/Number Combinations: Model numbers often use both letters and numbers. This may cause you to mistake a Z for a 2, or a S for a 5, and etc.. If you don't initially find any matches for your model number, you may need to try swapping a number for its look-alike letter (or vice versa).
Search Model with and without Marks: Some model numbers contain spaces, punctuation, dashes, or other marks. If you don't find any matches for your model number when including these marks, try searching the model without the marks.
