Recent updates to air conditioner parts have prioritized standardized fittings, yet many older units still require exact matches. I have analyzed these replacements by comparing manufacturer specs and aggregate buyer sentiment. You will find that while these components seem universal, tiny variations in the internal splines are the difference between a secure fit and a loose, spinning dial. Here is my honest ranking of your best replacement options.

Choosing Between Them
I recommend the Arctic Air 216591506 as the superior choice for most users because it is the official manufacturer part. While the GE replacement set is excellent for those looking to repair multiple units economically, the genuine article offers the best long-term peace of mind.
Always verify your specific model number before you finalize your purchase. These knobs look identical from the outside, but they often feature different internal splines that will not align with your specific unit. Choosing the wrong internal pattern is a common point of failure for many shoppers.
