Whirlpool FSP 3148954 Range Infinite Switch

Got this Whirlpool FSP infinite switch for an electric range. It's a Robertshaw part, model 3148954. It was pulled from a working unit, looks to be in decent shape with the standard 4-prong setup. If your stove burner isn't heating right or staying on high, this might be the fix you need. Pretty easy swap if you know your way around a screwdriver.
