Whirlpool Gas Range Control Knob Parts — Models & Compatibility

Your Whirlpool gas range control knobs take a beating — daily temperature adjustments, accidental bumps, and years of grease buildup eventually crack the plastic or wear out the D-shaped shaft connection. This hub covers the W10339442 control knob replacement, which fits most Whirlpool and Maytag WFG series gas ranges from the 2010s forward.

Is This the Right Part for Your Model?

Before ordering, you'll need to verify your exact model number. On most Whirlpool gas ranges, look for a metal tag inside the oven door frame or along the left interior wall when you open the door. The model number starts with "WFG" for Whirlpool gas freestanding ranges or "MGR" for Maytag models. This knob specifically fits the 320M, 505M, 510S, 515S, 520S, 525S, 530S, and 540S series — check your full model number against the compatibility list below.

About This Replacement Part

The W10339442 is a black plastic surface burner control knob with a chrome accent ring. It's designed for gas ranges and features the standard D-shaped shaft interface that connects to your burner valve stem. This part supersedes older numbers including WPW10339442, AP6019877, and 2311008. One common issue with these knobs: the internal D-shaped socket can round out over time, causing the knob to slip when you try to adjust flame height. If you notice the knob spinning freely without changing the flame, or if the plastic has cracked around the mounting area, it's time for a replacement. The knob simply pulls off the valve stem — no tools required for removal — but make sure the replacement fits snugly without wobbling.

Installation Overview

Replacing a range control knob is straightforward: turn off the gas supply at the shutoff valve behind your range (important safety step), then pull the old knob straight off the valve stem. If it's stuck, gently wiggle it side-to-side while pulling. Clean any grease or debris from the valve stem with a damp cloth. Align the new knob's D-shaped socket with the D-shaped valve stem and push firmly until it seats completely. The knob should feel secure and turn smoothly through its full range without binding. Test each burner position before pushing the range back into place.

Why Knobs Fail on These Models

Most Whirlpool gas range knobs fail for one of three reasons. First, heat damage from nearby burners — if you frequently use the rear burners on high, the front knobs can warp over time. Second, cleaning product damage — harsh degreasers or abrasive scrubbing can crack the plastic housing. Third, mechanical wear on the D-shaft socket — turning the knobs dozens of times per week eventually rounds out the connection point. If you're replacing one knob due to cracking or wear, it's smart to inspect the others closely. They've all experienced the same usage conditions and may fail soon after.

Ordering Multiple Knobs

If you need to replace all five knobs on your range, order them together to ensure color matching — plastic batches can vary slightly in shade. Most people replace just the damaged knob, but matching a 10-year-old knob's faded finish to a new one can be tricky. When in doubt, replace the full set for a uniform appearance.
