Worcester Bosch Control Knob 87161053850

The Worcester Bosch 87161053850 is a replacement control knob for Worcester Bosch heating appliances. It fits onto the control spindle and lets the user select and adjust the boiler setting by hand. The knob is a serviceable item, so it can be renewed on its own when the original becomes damaged or loose.

• The knob is cracked, split or has broken away from its mounting.
• The knob turns freely on the spindle without changing the appliance setting.
• The knob has come off completely and cannot be refitted securely.
• The control is stiff or difficult to turn because the knob has distorted.
• The position markings on the knob face are worn or no longer readable.

• Check the appliance model and serial number against the compatibility list to confirm the correct knob for your unit.
• Note the alternative part number 1014513 when cross-referencing older documentation or stock records.
• Confirm the spindle and control assembly are undamaged, as a worn spindle can cause a new knob to sit loosely.
