Reznor typically lists the model number on a rating plate attached to the heater cabinet. On many units, check the side or front of the cabinet, and look inside the access panel if the plate is not visible. The model number may include letters, numbers, and hyphens, so copy it exactly and do not substitute the serial number. Enter that model number in our search bar to narrow the complete Reznor unit heater parts catalog to parts that fit your specific unit. This model lookup covers the whole heater, not just the part you are repairing. Matching the number first helps you avoid compatibility guesswork and get your repair moving.
