4055986774 Genuine Universal Control Knob Kit 55mm Black with Decals for Electrolux Group Cooking Appliances, Kit Code UK-55B4

Worn, cracked or melted knobs can make a cooker look tired and hard to read. 4055986774 is a genuine Electrolux group universal knob kit in black, sized at 55mm and packed with decals so the settings can be marked once the knobs are on. It is also referenced as UK-55B4. No model list is held for this kit, so compare the shaft and mounting on your appliance before ordering.

Replacing worn or broken control knobs

Control knobs sit on the shaft of a gas valve, switch or thermostat and let you turn the setting. Over time they crack at the boss, lose their grip on the shaft, fade from heat and cleaning products, or get melted by a pan handle left too close. A knob that slips or spins can make it hard to set a burner or oven accurately, and a missing one leaves a bare shaft. A universal kit lets you replace a full set in one matching finish, with decals to put the markings back.

Fitting the new knobs

Make sure every control is in the off position and the appliance is cool. Pull the old knobs straight off the shafts rather than levering them sideways, then clean the panel. Line each new knob up with the flat on its shaft, push it home and apply the matching decal. Check every control turns smoothly and returns to off.

Questions about this part

Will these universal knobs fit my cooktop?

That depends on the shaft size and shape on your appliance and the space around each control, which we don't have on file for this kit. Measure an existing shaft and knob, or send your model number through the parts enquiry form and we'll check.
