Cooker hob query

[User62651]

I have 4 ring ceramic hob, Indesit, nothing fancy, maybe a year old. It is not an induction hob.

When you turn any or all of the 4 rings on they all heat up fully fine.

However issue occurs when a pan or pot is put onto the ring, after a short cooking time 80% of the time the inner part of the ring goes off and only the outer part stays on. When you take the pan off the ring usually goes back to full on (both inner and outer). This seems to be the case with all the various pot and pan types I have but occasionally I think the ring stays full on.

This happens the same with all 4 rings.

Is that normal? Some kind of heat sensor? The hob I had before this one which got broken did not do that, it just stayed on full.

As cook I want to be in full control of the ring heat!

Don't get it, it's not an induction hob so what's going on? Bad wiring, heat sensor, faulty unit, energy saving feature?

Has it always done it?

Yes it has

Slight concern the inner rings are shorting out when pan weight/metal applied, is that even possible through glass ceramic?
Guess the outer and inner ring parts must be on different circuits?

Does it then come back on during use? If so this is normal......

Get a glass saucepan see what temp is when inner goes off
Add some cold water in the pan and the inner ring should come back on again as the temp goes down.
It’s normal but you usually do not see it.

I would have thought is simply part of the temperature control.

My hob is part ceramic and part halogen and pretty sure it happens with the ceramic ones ( the halogen ones turn off completely).

Switching on and off of the element with ceramic hobs is normal. However the biggest factor is the pans you are using. A ceramic hob needs totally flat pans to allow the heat transfer from the glass, and most pans aren't totally flat. Best way to tell is take a metal ruler or something similar and hold it against the underside of each pan, most will only touch the pan at the outer edges which is why the hob gives the effect of being slow and why the elements switch off more regularly.
Just because a pan is listed as ceramic compatible doesn't make it effective on them. This is the main reason induction hobs are so much more better than ceramic.

That makes sense, thanks.
I think the fact the old hob didn't, to my knowledge, do this temp control thing was throwing me.
