Model Number Locator Tips
    1. A zero in the model number might be the letter O.
    2. A lower case L might be a 1.
    3. Some models have 3 digits and a period first, like this 555.66666666
Look for an aluminum tag--or a silver and white adhesive label in the locations illustrated below. The model number may be printed or stamped onto the tag and may be printed in different type sizes. NOTE: There may be partial model numbers on marketing stickers or in the owner's manual. These are often incomplete. For best results use the model number from the tag.
