When a knob on my Samsung Gas Range cracked during a busy cooking session, the first instinct was to call a repair service. Then I priced a service visit, which was more than the stove was worth to fix, and realized the part itself could be replaced in under a minute. The DG64-00473A burner control dial knob set is exactly that part. It ships as five replacement knobs designed to fit the Samsung NX58 series gas ranges, and after a month of daily cooking on a repaired cooktop, the fix has held up completely.
The product is not glamorous, and it should not be. A range knob is a simple machine with one job: turning a gas valve smoothly and reliably. What matters is whether the replacement fits the shaft, turns without binding, and looks close enough to the original that no one notices the swap. This set clears all three bars.

Design and Build
The DG64-00473A knobs are molded from a matte plastic that closely matches the finish of the factory Samsung parts. The shape follows the original design: a rounded body with a clear front face, a metal insert on the back that grips the valve shaft, and the raised marking area where the model numbers appear. The weight feels right, which matters because a feather light knob can feel cheap and a heavy one can feel wrong on the valve.
The rear of each knob has the metal D shaped insert that engages the splined shaft on the Samsung range. That insert is the piece that actually does the work, and it is crimped firmly into the plastic body. I pulled and twisted the knobs during testing, and the insert never loosened or spun inside the housing.
The one thing to note is the color. The batch I received was a close match to the dark finish on my NX58 range, but replacement parts can vary slightly between production runs. If you have a white or a different accent color range, check the finish against your own stove before ordering.
Key Features
Five knobs in the package is the headline. A typical Samsung NX58 gas range has five control points: four burners and the oven. That means this single set can replace the entire cooktop control bank, with nothing left over and nothing missing.
Stove Knob" width="1200" height="800" loading="lazy" style="height:auto">Compatibility is the other defining feature. The listing explicitly names the NX58H5600SS, NX58F5700WS, NX58H5650WS, NX58J7750SS, and NX58M6850SS models, and the DG64-00473A part number matches the factory part used on those ranges. If your stove is one of those models, the fit is direct with no adapter or modification.
Installation is genuinely tool free. The old knob pulls straight off the shaft with a firm tug, and the new one presses on until it seats. I replaced the cracked knob during a dinner prep break and had it back in service before the water for pasta boiled.
Real-World Performance
The real test of a stove knob is how it feels a month in, not how it looks on day one. After four weeks of daily use, the replacement turns with the same resistance as the factory knobs still on the stove. The valve detent clicks are crisp, and the knob does not wobble on the shaft even when you grip it near the end.
Heat resistance is the concern most people skip. The knob sits close to the burners, and on my range the rear burner heats the surrounding area noticeably during long boils. The replacement stayed cool enough to grip comfortably throughout testing, and the plastic showed no warping, melting, or discoloration even after the front burner ran at high for forty minutes.
I also pulled the knob off and reinstalled it several times to simulate cleaning and future swaps. The metal insert kept its grip on the shaft with no stripping, and the plastic body showed no stress marks. For a part that costs a fraction of a service call, that is exactly the durability you want.
The knob stayed securely attached through the month without any tendency to loosen. A range knob that spins freely on the shaft is both annoying and unsafe, because the printed position indicator stops lining up with the actual valve setting. On this set, the knob tracked the valve position precisely through the full range from off to high, and the indicator markings stayed aligned with the burner labels throughout testing.
Replacing the remaining knobs proactively made sense after the first one proved itself. Since the set contains five pieces and a range has five controls, I swapped the four original knobs that were still working for the new ones, keeping the cracked original as nothing more than a memory. Every knob now matches, which tidies up the look of the cooktop and means every control on the range has fresh, consistent feel under the fingers.
The only shortfall is cosmetic. The replacement does not have the same subtle texture and printed markings as the original in every light, and if you are the type to inspect a cooktop closely, you may spot the difference. Functionally it is indistinguishable.
Pros and Cons
Pros:
- Five knobs cover the entire NX58 control bank in one order
- Direct replacement with a firm metal insert for a reliable grip
- Tool free install in under a minute per knob
- Heat resistant material holds up to daily cooking
- Matches the factory finish closely on the models tested
Cons:
- Finish can vary slightly between production batches
- Printed markings do not perfectly mirror the original
- Only covers the NX58 series, not every Samsung range
How It Compares
You have three realistic options when a Samsung range knob breaks: the DG64-00473A replacement set, an aftermarket universal knob, or a factory service appointment. The comparison comes down to fit, price, and certainty.
| Feature | DG64-00473A Set | Universal Aftermarket Knob | Factory Service Call |
|---|---|---|---|
| Knobs included | Five | One or two typically | Part plus labor |
| Direct fit on NX58 | Yes, verified | Depends on spline size | Yes, OEM |
| Installation | Tool free, one minute | Tool free | Technician visit |
| Cost | Low | Low | High |
| Finish match | Very close | Often generic | Exact |
The universal knob is cheaper per unit but a gamble on fit, because spline patterns differ between manufacturers. The service call is the most certain route but the most expensive by a wide margin. The DG64-00473A set splits the difference: verified fit for the NX58 series at a price that makes the repair a ten minute decision.
Who Should Buy It
Buy this set if you own one of the listed Samsung NX58 ranges and a knob has cracked, melted, or gone missing. It is also a smart spare to keep in a drawer, because five knobs in the box means you are covered the day another one fails.
Skip it if your range is a different model or a different brand, because fit is not guaranteed outside the NX58 line. If your stove matches, this is the cheapest way back to a fully functional cooktop. You can check the current price for the DG64-00473A knob set on Amazon if you need it today.
How We Test
I installed the DG64-00473A set on a Samsung NX58 range and used it as the primary cooktop for one month. I tracked installation time, knob feel, heat resistance during long boils, and how the metal insert held up to repeated removal and reinstallation.
I also verified the fit against the five model numbers in the compatibility list and ran the high heat test on the front burner for forty continuous minutes. For a broader understanding of how Samsung ranges and their parts work together, Consumer Reports range buying guide is a useful reference on what to expect from these stoves.
