We had a problem yesterday with our Cannon York Electric cooker which
we have owned for 2 years.

My wife put a couple of quiches in the oven which only normally took
20 minutes to cook. On checking them after this time they had turned
completely black which alarmed us. The element in the back of the
oven was glowing bright orange and the only way to cool the oven down
was to switch it off at the electric.

Later in the day, my wife put the Sunday roast in the oven as it now
appeared to be working fine. We were sat watching the TV when
suddenly we heard a big smash like something had fallen off the work
surface. What had happened was that the temperature in the oven was so
hot (although the dial was only on 180 degrees) that the inner glass
window had shattered into thousands of pieces and was all over the
kitchen floor, the oven floor and even in the second oven above.

I turned the power back on at the mains this morning and the oven
immediately came on even though the dial was set to the off position.

My wife spoke to Cannons this morning who basically didnt want to know
even though this seems to be a very serious design flaw if the glass
can shatter like that without any obvious tripout mechanisim in place
to shut down the oven should it reach a certain temperature.

What it now means is that we need to go and buy an new oven only 2
years after paying over £400 for one that should have lasted a lot
longer than it has done

Household insurance.

Thermostat was obviously faulty.

Did think about this.
Would hosehold insurance cover it?
what would it be classed as?

Did you buy the cooker new? If so, even though it is now probably out of
warranty, you might still have a claim for it being unfit for purpose. I
think that the Which website might have some information, or ask at the
Citizen's Advice Bureau. Clearly the stat has failed. I wouldn't have
thought that your house insurance would cover it, but persistence might
get you your money back.

Failing all of that, you should be able to get the stat replaced for
less than 100 pounds. You could buy a new door from somewhere like
espares and fit it yourself. www.espares.co.uk

Good luck!

Thanks for the advice. As the oven comes on as soon as the mains is
switched on, does this still point to the thermostat as the oven gets
warm even when the dial is set to 0.

Again, thanks in advance

[Topref]

Things are definitely pointing at the thermostat. Heating up when dial on
Zero? - Thermostata not doing it's job and cutting power/maintaining correct
temp.

Thanks to everyone who has replied so far. Looking at the espares site
it seems I may be able to pick up a thermostat and glass for under £50
(minus delivery)

Are you 100% sure about this?

If the oven turns on when the switch is off then this is obviously a switch
fault.

The thermostat may also be faulty, but it is quite likely that if there is a
faulty switch then the thermostat function will be ignored.

Given the severity of the fault, and that the oven has been used 'to
destruction' I would be very wary about trying to repair it.

If the cooker is only two years old, and has suffered a very major and
potentially dangerous fault then it is likely that you are entitled to your
money back or a replacement.

'Which' and the CAB are good resources; AFAIK you should be going back to
the retailer who sold you the cooker as your contract is with them. Check,
but if they tell you to go to the manufacturer they are probably just trying
to duck out of their responsibility.

If you bought via credit card the card company is jointly liable.

I agree with David, all of my cookers switched of, they did not simply
rely on the thermostat to sense zero. If they did it would make useful
source of frost protection! ;-)

I think some have the thermostat combined with the on/off switch -
maybe the switch contacts got welded together so the thermostat bit
didn't open them when pre-set temp was reached ?

I presume there must be a thermostat sensor somewhere in the body of the
oven which is connected to the back of the switch to allow the switch
setting (temperature) to control the oven.

There is therefore more than one component which may have failed.

I say again, if the oven has malfunctioned enough that the inner door has
shattered due to a massive over temperature then almost anything in the oven
could have been stressed beyond the design tolerance.

Replacing parts which MAY have failed and hoping everything else is O.K.
does not seem a sensible approach.

The oven should be returned as 'not fit for purpose' to the merchant who
sold it to the OP.

Next time the door may not shatter before the entire kitchen catches fire.

There is usually a capillary sensor - the thermostat sensor and switch
are a combined unit. A new switch will have a new sensor.

Replacing parts which MAY have failed and hoping everything else is O.K.
does not seem a sensible approach.

But replacing the single part which _has_ failed is quite sensible. It
isn't exactly an uncommon failure.

All you are entitled to is repair (assuming you can show the fault
existed at the time of sale).

Ii isn't the fact that the part failed - it is the consequences of the
failure. The oven was stressed enough to shatter an inner glass door - so it
has damaged other parts than the switch/thermostat (obviously).

It is neither obvious nor likely that other parts are damaged. The
glass door is toughened - which means that any surface imperfection
and not merely heat could have contributed to its failure.

The question
now is what else has been damaged in perhaps a less obvious way.

Such as? Cookers are not exactly complex and the fail safe is a very
simple one - they can survive full power for an extended period as
temperature equilibrium occurs at about 300deg C. This isn't far off
the temperature some use for a self cleaning cycle.

Are you prepared to give a 100% guarantee that, even though the oven was
heated enough to shatter a glass door, all that will need replacing is the
switch/thermostat?

Why not? What else do you suggest will have been "overstressed"?

It may be common for thermostats to fail.
Is it common for glass doors to shatter?

Probably more common than it is for thermostats. The inner door is
just a bit of toughened glass.

All you are entitled to is repair (assuming you can show the fault
existed at the time of sale).

Absolutely not.

A fault which develops during warranty doesn't have to be shown to have
existed at the time of sale.

The cooker is out of warranty.

Equally, goods are expected to be durable - to last a reasonable amount of
time. This means that if they are out of manufacturers warranty you still
have rights.

You may have the right to a repair as I stated. However the burden of
proof is on the buyer to show non-conformity at the time of sale is on
the buyer, not the seller.

You are therfore entitled to repair (where appropriate), refund or
replacement if the goods fail sooner than can be reasonably expected.

You will be entitled to a partial refund rebated to take into account
the use you have had from the device if both repair or replacement
(with a second hand device if necessary) are not feasible.
