450920570 Genuine Control Knob for Glen Dimplex Group Ovens and Cooktops, Cooker Knob Replacement Part

This is a genuine Glen Dimplex control knob, part number 450920570, from the group's range of cooker knobs. Knobs in this series cover ovens, hotplates and gas burners, and they differ in finish, markings and how they grip the control shaft. The part number appears in your appliance's parts list and is sometimes moulded inside the knob, so use that to confirm 450920570 before ordering.

When a cooker knob needs replacing

Knobs are the most handled part of any cooker. Repeated heat cycles make the plastic brittle, and the socket inside can split, letting the knob spin uselessly or fall off. Grease and harsh cleaners wear away printed symbols and bright finishes. On gas burners and ovens, a knob that doesn't sit firmly or show its position clearly makes it too easy to leave something on. A replacement knob is a quick fix that restores control and makes the cooker look tidy again.

Fitting the replacement knob

Turn the control to off and let the cooker cool. On gas models, confirm the burners and oven are out before you start. Pull the old knob straight off, check the shaft for damage, and clean away any grease around it. Press the new knob on with its socket lined up to the shaft flat, then turn it through every position to make sure it reads correctly.
