How to replace an oven thermostat？

I'm gonna show you how to replace the thermostat in this electric cooker. the process for replacing the thermostat will be really similar for almost all domestic electric comments. for example, we have a thermostat that control sits behind the temperature knob,  then you can runs the wire around the back of the oven. And this capillary tube is then seated at the Top of the oven cavity.

How do you know if your thermostat got damaged? There's three main signs  

First sign is that if the temperature inside the oven is reaching what you've set it to on the temperature;

the second sign is if the temperature inside the oven is always at maximum, no matter what you call it setting;

The last sign is if you're not hearing the telltale.  click when you turn the controlling knob,  it's a sign that you need to replace the thermostat,

Keep safety first to make sure that your oven is switched off at the mains before you get to work, it should be a switch in the general vicinity or if you can't see it, it might be one of the units above below or to the side of the cooker, but to make sure it switched off,  faster is situated at the back of the cooker.

So if you've got a built in thermostat, then you'll need to remove it from its cavity. You can do this by removing these fitting screws here and then lifting the oven out of its cavity and unplugged indicators once you've got the oven into an open space in an enough space to work on it, you can get started.

The first thing you need to do is just remove the door. most of indoors there will be a latch on either hinge, that when it moved into the open position will allow you to close the door up and lift it out. We can see the thermostat's capillary tube, which is situated at the Top and back of the oven cavity, you just need to unclipped it. and now we need to remove the back panel from the cooker is held in place by trox had squeezed,  we just gonna use the trox bit on the end of a screwdriver. These two Top panels as well. Snap spun the cook around and we can see the wire from the Top of the cooker round and into the oven cavity. So I can now just pull the capillary tube out of the cavity. To just remove fixing back it here. Again, trox had screws keeping it in place.  

the first is just Mark one of these white wires with a pen.  On the second, it's just take photo this way. I know when I come to put my new fantastic thermostat in so that I can wire in exactly the same way as this one, I can just remove the clips. I can then just remove the control of from the front and now I can take these two screws out and remove the old thermostat control, and put that one side, get a new one.  I'm gonna fix it to the front control panel, rewrite it, feed the wire through, put the capillary tube back into the oven cavity and fix it all back together. It's just put the panels in the door back onto the oven, don't forget to put the latches down on the door when you really fitting it. The thermostat on an electric cooker before we get cooking again, it's the best to give it a bit of a clean inside the oven cavity.
