** Kenmore diswasher mode number 665.1728 **
That is only the first part of a model number. Did you get it right off the appliance’s model and serial number identification tag? That is the only reliable place the complete information will be found.
You can find tips for locating the model number identification tag on your appliances in the ‘Repair Parts’ section of my web site linked below.
