AO Smith places the model number on the rating plate attached to the side of most water heaters, often near the upper portion of the tank. Check around the front or side of the unit for a label marked "Model," "Model No.," or "M/N." Copy every letter, number, and hyphen exactly as shown. Type it into the model number search to pull up the parts matched to your unit. Using the complete model number narrows the catalog for the entire water heater, not just its cap, lid, or cover. That means fewer wrong orders and a faster repair.
