How to Replace DG94-00945A Range Burner Knob on Samsung NX58H9500WS — Step-by-Step

You reach for your Samsung range knob to adjust the heat, and it either spins freely without engaging, pulls off in your hand, or won't turn at all. The DG94-00945A burner knob dial is one of those parts that gets touched hundreds of times — eventually the internal grip mechanism wears down or the plastic cracks. Good news? This is probably the easiest appliance repair you'll ever do.

What You Need Before Starting

This replacement requires zero tools and takes about 30 seconds per knob. You won't need to shut off gas or power for this repair — these knobs simply pull off and push on.

• Replacement DG94-00945A burner knob (order one for each damaged knob)
• Your hands (seriously, that's it)

Repair Time: 1-2 minutes per knob
Difficulty: ● Beginner — No experience needed

Safety First

While you don't need to disconnect anything, make sure all burners are completely cool before starting. If you've been cooking, wait at least 30 minutes. You're working directly above the burners, and hot surfaces can cause serious burns even if flames aren't visible.

Step 1: Remove the Old Knob

Grip the knob firmly and pull straight out from the control panel. Don't twist — just pull. If it's stuck, wiggle it gently side-to-side while pulling outward. The knob sits on a D-shaped metal shaft, and years of cooking residue sometimes creates a sticky bond. If you're replacing a broken knob that's already loose, it'll come off with barely any effort.

Step 2: Clean the Control Shaft

With the knob removed, you'll see the metal shaft sticking out from the control panel. Wipe it down with a damp cloth to remove any grease or food buildup. Check the shaft shape — it should have one flat side (D-shaped). If the shaft itself is damaged or rounded off, you've got a bigger problem that requires a control valve replacement, not just a knob.

Step 3: Align and Install the New Knob

Look inside the back of your new DG94-00945A knob — you'll see a D-shaped opening. Line up that flat side with the flat side of the control shaft. The knob only fits one way. Push straight in until you feel it seat completely against the control panel. There should be no gap between the knob and the panel surface.

Step 4: Test the Operation

Turn the knob through its full range, from OFF through all heat settings. It should rotate smoothly with definite click positions at each setting. Try turning it all the way to the LITE position and back to OFF several times. The knob shouldn't wobble, slip, or feel loose. If it does, pull it back off and check that it's fully seated on the shaft.

Which Models Use This Knob?

The DG94-00945A fits Samsung slide-in gas ranges including NX58H9500WS, NX58H9950WS, and NY58J9850WS models across multiple revision codes (AA-00 through AC-03). This knob replaces older part numbers DG68-00377A, AP5957989, and PS10067150. Check your model number on the label inside the oven door or warming drawer to confirm compatibility.

Frequently Asked Questions

Can I use this knob on other burner positions?

Yes, all five burner knobs on these Samsung models use the same DG94-00945A part number. They're identical and interchangeable. If you have multiple worn knobs, you can order several and replace them all at once for a uniform appearance.

Why does my knob keep falling off after installation?

If the knob won't stay on, the control shaft itself may be worn or damaged. The D-shaped shaft can round off over time, especially if someone forced a misaligned knob onto it. Remove the knob and inspect the metal shaft — if it looks rounded instead of D-shaped, you'll need to replace the control valve assembly, not just the knob.

Do I need to match the knob markings to specific burners?

No. The temperature markings on the knob face are universal across all burner positions on these Samsung models. The actual heat output is controlled by the valve behind the panel, not by the knob markings. You can install any DG94-00945A knob in any position.
