Help with problem solving an electric hob.

[ChristianBkr]

Hey all, hopefully one of you kind people can help.
Our cooker died, so we hastily purchased a reconditioned one from a local white goods charity. The warranty is only valid if they deliver, I assume its because of dmage in transit or the like, but we needed the cooker immediately, but they could not deliver for two weeks. So we took it away ourselves, hence no warranty. The cooker was fitted with 4 brand new hobs.
3 months have passed and the hobs have started failing.
One of the small ones works perfectly. The other three are next to useless. One gets hot, but not hot enough to boil water. One gets warm, the other only gets warm when none of the others are switched on. On a side note, one of the knobs gets hot and starts to melt when all of the hobs are switched on.
The oven and grill both work perfectly, though the grill only seems to do full heat or off with nothing in between, not sure if that is relevant. And the cooker is a belling, not sure what model.
I am pretty handy when it comes to repairing/replacing bits and pieces, so would like to try and fix this myself, if anyone could point me in the right direction as to what may be wrong.
Many many thanks if you can help.

Edit: its a 335 an I found the model on a plate insode the oven door.

I would question there warranty conditions and whether they can get away with this
All appliances have to be fit for purchase and last a reasonable length of time. Also a period of 2 weeks to wait for delivery is unreasonable for a customer like yourselves whos cooker has failed completely. I would have a word with consumer advice and see what they say. From my point of veiw I could understand there being no guarentee on the parts that could break during transit but thats all

Back to your problem

The grills problem will be the simmerstat the control at the back of the knob
The rings are a bit more difficult since I have no model to find out what type of rings are fittd but the knob melting give me pause for concern and leads me to the conclusion you need a professional to look at it

Perhaps melting is too strong a word. The part of the knob that slides onto the regulator gets hot and pliable. So when you try to turn the knob, it doesnt really do anything, as it just spins off and around.
Ideally I would get a proffessional to look at it. But its a case of watching the pennies or lack there of. Its a Belling 335 cooker. And they are the solid round hob elements. Nothing fancy.
I have questioned them about the warranty, but to no avail. Im sure I could probably chase it further, but the cooker only cost £60. Its a charitable organisation and according to the repair receipts, the new hobs cost more than I paid for the cooker. So I think its one problem Im going to let slide.
Im going to attempt to repair it more out of necessity than anything else, so any pointers you could give would be greatly appreciated.
I have located a simmerstat from an ebay seller for under £7 so that will be mended soon. Thankyou for that 🙂

Re: Help with problem solving an electric hob.

if i have the right info, to control the rings the knobs click round through 6 positions

there can be only 2 faults if this is the case

1) the rings have failed these rings have 2 elements and if one fails they dont get very hot
2) the control switches have failed. these switches have about 5 contacts and you should be able to inspect them and look for overheating and see whether the switches operate correcly. you could buy 1 switch as a test or swop the good switch around to see if another ring works
make sure you take good photos and diagrams of all wiring before you start and of course make sure the electric is off before you start
