Robertshaw Blue Control Knob Stem Insert - 4590-602

This is a Slip-Fit shaft-adapter insert for a compatible control knob, not a complete knob.

Part details: These are interchangeable-position adapter inserts only when the matching Slip-Fit knob and appropriate control shaft are used.

Control compatibility: Verify the specific Robertshaw control series and stem/dial arrangement; similar overlays, inserts and knobs are not automatically interchangeable.

Before ordering: Identify the exact control-series number on the original thermostat or valve and compare the dial scale, direction and shaft dimensions. Match the insert color or listed stem dimension, control shaft flat and compatible knob series; different colors can indicate different stem sizes.

Fitment: Use the complete appliance model number and compare the original part before ordering. Appearance alone does not establish compatibility.
