What if I can't find the part number on my cooktop? Is the number inside the knob useful? If so, it's 318 1966.

Answer Hello Doris! The 3181966 pulls as a Whirlpool discontinued trim vent. We will need your appliance model number to verify the correct knob. Here is our model number location tool to help verify the location of model numbers, thanks! http://www.appliancepartspros.com/modelnumber_locator.aspx
Is this one knob or a set of 4?

Answer This is a single knob. Knobs are generally fairly expensive and are priced around $15 to $35 each depending on brand and model.
