Learn how to replace a broken cookware lid knob in a few simple steps. Save money and avoid buying a new lid with our easy guide.

Quick Answer

You can replace a broken cookware lid knob yourself in about ten minutes with a screwdriver and a replacement knob assembly. This fixes the lid without buying a new one, saving you money and reducing waste.

Why Replace the Knob Instead of the Lid?

A broken knob doesn’t mean your cookware lid is useless. Replacing just the knob is far cheaper than buying a new lid, and it keeps your favorite pot in service. It’s also a simple DIY task that most people can handle with basic tools.

For RACO cookware, complete knob assembly kits are available that are affordable and easy to install. These kits include everything you need, so you don’t have to hunt for parts.

What to Check Before You Start

Before ordering a replacement, confirm the knob style and the lid diameter. Knob assemblies are not universal—they can vary in screw spacing and base shape. Measure the distance between the screw holes and compare it with the replacement’s specifications.

Also, check whether the knob is attached with a screw from the top or a nut from underneath. This affects how you remove it and what tools you’ll need.

Step-by-Step Replacement

Gather Tools and Replacement Knob: You’ll need a screwdriver (usually Phillips or flathead) and the replacement knob assembly. Check that the new knob matches the screw hole spacing on your lid. If the screw holes don’t align, the knob won’t fit—measure twice before ordering.
Remove the Old Knob: Turn the lid upside down and locate the screw or nut holding the knob. Loosen it with the screwdriver. If the screw is stuck, apply a little penetrating oil and wait a few minutes. Don’t force it—stripping the screw will make removal harder.
Clean the Lid Surface: Wipe away any food residue or grease from the knob area. This ensures the new knob sits flush and the screw tightens properly. A clean surface prevents the knob from loosening over time.
Attach the New Knob: Place the new knob over the hole, align the screw holes, and insert the screw or nut. Tighten firmly, but avoid over-tightening which can crack the knob or strip the threads. Snug is enough—if you feel resistance, stop.
Test the Knob: Lift the lid by the knob and give it a gentle twist. It should feel secure and not wobble. If it moves, tighten a bit more. A wobbly knob can become a hazard during cooking—fix it now.
