"Cooker: Leisure Cookmaster 101 One of the hob regulator

This answer was rated:

"Cooker: Leisure Cookmaster 101

One of the hob regulator knobs has fallen off and is in 3 parts, black knob, spring and 'chrome' flange - putting it back together, it's possible to regulate the gas, but the knob doesn't 'hold' and stays loose.

How does the knob fix correctly...."
Look at the knob part, is the part that fits on the shaft split?
Is the metal piece in the flat side missing?

Hmmm not sure... doesn't look 'split' but can't see a metal piece on the flat side. Knob seems to fit snugly on the shaft

If it's snug it will take some effort to fit it, does it?
When it's fitted, does the knob turn and the shaft stay still?
Does the shaft turn easily with pliers?

1. knob slides on fairly easily

2. knob turns shaft (i.e. regulates hob)

3. can turn shaft by hand (i.e. pliers not required)


OK, so the knob is loose.
There's a small metal piece missing from the flat.

If you pull one of the other knobs, you should see what it looks like.

Alternatively, a thin sliver of cardboard, cut to size of the flat side of the shaft, should be enough to take it's place and make the knob a better fit.

Try it, let me know how it goes.

ah, ok - will give it a go

OK, if it doesn't work, you need a new knob for the cooker.

Good luck with it.

Hope this helped

checked 2x other knobs and neither had a metal piece - however a bit of cardboard has done the trick!


it's probably on the knob we use the most, so maybe it's a bit of extra wear-and-tear


I've swapped the knobs around so the 'damaged' knob is now on the least used hob


many thanks
