The Alto-Shaam KN-3474 Thermostat Knob allows operators to adjust the temperature setting on compatible holding cabinets within a 15-90°C range. It provides a clear control point for selecting the desired heat level during food holding and warming operations. This knob can be used when the original control knob is worn, cracked, missing, or difficult to operate. Installing the appropriate knob restores convenient access to the cabinet’s temperature control. This is intended for use with applicable holding cabinet models. Check the equipment model and part number before ordering to verify the correct application.
