Understanding the Problem
What this part is and what it fixes: The listed numbers (74007733, AP6011505, PS11744702) are common replacement part numbers for a stove/range burner control knob. The knob interfaces with the valve stem or infinite switch shaft to set burner flame levels or power settings. A failed knob prevents you from accurately controlling the burner or from turning the burner on/off safely. Step‑by‑step diagnostics and repair: 1. Confirm the symptom a. Try to turn the existing knob: does it slip, wobble, or pop off? Does it not rotate at all? Is the indicator misaligned or melted? b. Smell for gas: if you smell gas, stop and follow the safety note below before continuing. 2. Check the knob only (quick test) a. Power/gas off: for safety, turn off the range control (all knobs off) and the gas supply to the appliance if you will be working near the valve stems. b. Pull test: Most control knobs are friction-fit—grasp and pull straight out. If it comes off easily and the shaft looks intact, the knob is likely bad. c. If the knob is retained by a screw or clip, remove the small retaining screw on the face or behind the control panel trim using an appropriate screwdriver and then pull the knob. 3. Inspect the shaft and knob a. Inspect the valve stem (shaft) for damage: stripped splines, rounded corners, or missing metal. If the shaft is damaged, replacing the knob won't fix it. b. Inspect the knob bore: look for stripped plastic splines, cracks, melted sections, or missing retaining features. 4. Replace the knob (how to fix) a. Obtain the correct replacement: use one of the part numbers (74007733, AP6011505, PS11744702) that matches your model and spline count/shape. b. Align the knob: line up any flat or keyed side of the knob bore with the valve stem flat or spline orientation. Push straight on until it seats fully. If the knob uses a retaining screw, position it and tighten snugly—do not overtighten. c. Restore gas/power: turn the gas back on if you shut it off, and restore power to the range. d. Test the burner: turn the knob through all settings. Verify the igniter clicks (for spark ignition), the burner lights, flame size changes smoothly with knob position, and there is no wobble or slipping. 5. If replacing the knob didn’t fix it a. If the knob fits but the stem does not turn the valve (knob turns freely on a fixed shaft or nothing changes at the burner), the valve stem or internal valve (or infinite switch on electric burners) may be damaged and requires valve/infinite switch replacement by a qualified technician. b. If you detect gas leakage or inability to shut off the flow, stop and contact a licensed technician immediately. Safety note: Always work with gas appliances cautiously. Turn gas off at the appliance or main shutoff before disassembling controls. If you smell gas, evacuate, shut off the main gas supply if safe to do so, ventilate, and call your gas utility or a professional. If you are not comfortable working on gas valves or the valve stem appears damaged, hire a licensed service technician.

Helpful Repair Tip
Try removing the knob and rotating the valve shaft with needle‑nose pliers while the knob is off (with gas off) — if the valve turns smoothly and controls the flame, the knob is faulty; if the shaft is stuck or slips, the problem is the valve/stem, not the knob.
Frequently Asked Questions
Can I replace a broken stove knob myself?
Yes — most stove burner knobs are user‑replaceable: power and gas off, pull the old knob straight off (or remove a small retaining screw), inspect the valve stem, align and push the new knob on, then test. If the valve shaft is damaged, or you smell gas, stop and call a licensed technician.
The new knob fits but the burner still won't change flame — why?
If the new knob turns but the burner flame won't change, the issue is likely the valve stem or the internal gas valve (or the infinite switch on electric models). That means the control shaft isn't converting knob rotation into valve movement; repairing that requires replacing the valve or switch and is best handled by a qualified service technician.
