Product review (5 stars): Whirlpool replacement knobs, years in the replacing
A few years ago a couple of the burner knobs wore out and broke off my Whirlpool gas range. In attempting to replace them I discovered how difficult it can be to find factory parts for broken appliances. The store I bought the range from didn't sell replacement knobs, though they offered to sell me a new range (!) My husband tried replacing them with cheap universal knobs from a big box store, but those didn't match the finish and design of the range,  and they always fell off after being touched or bumped. We approached a local appliance repair shop to find out about ordering replacement knobs, but the price they quoted ($125.00 for four knobs) was more than we felt was reasonable given the knobs the range came with were little more than thick molded plastic. We couldn't find the same Whirlpool knobs anywhere online either. We made do using our range without knobs for some time, which was doable but less than ideal.

A couple months ago, in the middle of a kitchen renovation, I decided to check again to see if I could find the knobs our range needed. The first place I checked was Amazon, and I was surprised to find these knobs. Not only were they authentic Whirlpool knobs, they appeared to be the same part original to our range. On top of that, the price per knob was fair. It would cost less than $50.00 to outfit my range with a new set of knobs. Sure beats spending $125.00 +tax. Having had no luck in my previous search for the appropriate knobs, I half expected to be disappointed if I ordered these. But I did, and they're perfect. They are indeed the same factory knobs I searched for years ago, but for a fraction of the price the local appliance repair shop quoted.

There's not much else I can say about the knobs themselves-- if you own a white Whirlpool range manufactured within the last decade or so these knobs should work (check your owner's manual to be certain). They couldn't be easier to install: slide them on the burner stem (sorry, I don't know the technical term for it) and they're ready to use. The original knobs on my range lasted about six years before they weakened and broke, so I expect about the same from these. Since I plan to replace my range in another year or so I imagine this set of knobs will hold up fine during that time. The most important thing to me is that I finally have a fully functional range, and cooking is a pleasure again!
