Hi I'm Josh from eSpares.
And in this video I'll be helping you to diagnose problems
in your oven. If you're oven is like this one
and the display is flashing and some parts of it are working normally such as
the grill.
But the main oven won't turn on it may be that the clock
needs resetting. Sometimes following a power cut
the clock resets itself and you can see how to reset the clock
by consulting the instruction manual that came with you oven.
If you can't find your manual then you may be able to download it from the
eSpares website. Now if the oven
has no display at all and has no power getting to it
then you need to check the power supply.
First have a look at the wall switch where it's connected.
If the wall switch has an indicator lights make sure that that's on to show
that this power there.
If there's a socket on the walls which try plugging
another appliance into it such as a kettle to make sure
there's some power there as well If there isn't any power at the wall switch
check the fuse box in your house. On the other hand
if there is power at the wall switch then that would indicate a problem
with the Oven. Now it may be an issue with the terminal block
on the oven and this is located on the back.
I'm just going to turn this off and turn it around so we can have a look at the terminal block
on it.
This is the terminal block here
on the back also make sure you have disconnected the oven when you do this.
And you can see how the cable comes in and screws into these
terminals here. Those cables have got to be screwed in
really tightly, if they're not this can lead to burning and other damage.
Just have a look for any signs of burning
around the block. If you can see anything that we recommend just
replacing the part altogether
and make sure those cables are screwed in tightly.
If the terminal block looks okay the next thing you need to check
is if there are any thermal cut-out in the oven. Now on this particular model I
need to remove both the top
and the back panel to access the cut-outs inside.
Now this is the thermal cut-out
here, and you need to test this using
a multimeter. They should show up
as a short circuit if they're working correctly so
reading less than a couple of ohms. Obviously any reading that's
dramatically different to that would indicate that the presence of
a fault and you need to replace the cut-out.
If you are getting a reading of a short circuit the most likely cause
of no powers to the oven is a faulty Control Board
and you need to replace the control boards. Now usually it's very difficult
to prove the presence before with the board
in which case you will just need to replace it . Now I have got the back of the
oven let's look at a couple of other problems that can occur.
If you're not getting any heat from the elements you can test then
using your multimeter. Just place the meter
onto a low resistance setting. And then put the probes of the meter
onto this terminal of the element this one here
is the main fan element
so I'll just put the probes on and for working element he should be looking for
reading have less than a hundred ohms and anything dramatically higher than
that would indicate the presence
of a fault. On this element my reading is about twenty six Ohms.
And on the grill element here 55 Ohms
and 35 Ohms. So again it shows that both those elements are working OK.
This Oven also have a third element here at the bottom so if it's
the same on your Oven make sure you check
all the elements for functionality.
Another problem that can arise is noise from the fans. either the
cooling fan here on the top, or the circulation fan.
This is usually caused by dry or worn out
bearings on the motor. So you can usually resolve the problem by just
replacing the relevant fan motor as
necessary.
Now if you're oven has a temperature indicator light you can use this to
determine
whether the fault lies with the thermostat or the element when you Oven
isn't heating up properly.
When you first turn the thermostat on the light should come on
and will turn off once the oven has reached the correct level.
If there's a problem with the elements that lights never going to turn
off
because it's never going to hit the correct temperature. On the other
hand
if when you turn the thermostat on the light does not turn on at all.
That shows that shows there's a problem with the thermostat. Of course in either case you
can replace
the faulty part. One final tip to bear in mind
is that you can prolong the life of the element in your oven
by turning it down to its minimum temperature when you finished cooking
just for a couple of minutes. And that helps the circulation fan
to get rid of any heat that's left in the element and prevent it from
overheating. If you need help diagnosing
other issues in your appliances, check out our other eSpares videos.
And spares for Ovens along with other appliances are available
on the eSpares website. Thanks for watching.
