Cooker Switch Melting Delonghi

[jbjbjb]

I have EXACTLY the same problem as above! I have replaced my oven selector switch 3 times in the last year and the last one only lasted a month!, it has melted each time in exactly the same place as the previous post above, so it looks like I have to change the connector wire and the crimps attaching to the switch (again suggested above).
But my question is what sort of wire is needed and where would you buy the wire and crimps? Being a DIYer I’m not sure where to source these bits. I’ve got a new switch ready to go but no point replacing it without a new wire if this is part of the issue

also check with manufacturer, see if there's a recall, seeing as 2 posters have both had the same problem.

Probably your best bet for a replacement crimp is to use one of there that can be done with a normal insulated crimp tool:

The red one will work if your cable is 1mm CSA, or the blue one if 1.5mm, if unsure get a couple of each and check when you strip the wire, if it fits the red one use it, otherwise blue! Get a proper ratchet crimp tool if you don't already have one, something like:

That’s great! Many thanks! So will I be ok using the existing wire or should I replace this too?

If the wire looks OK then just cut the old crimp off leaving as much conductor as possible, and crimp the new flag style terminal to it after stripping it carefully.

Let us know how you get on. As already mentioned, look for any recall info, etc, as it might have been a bad batch of switches or similar, but a push-on terminal that is not well connected can cause a fair amount of heat.

Awesome, thanks again, hopefully this will be the last time I have to replace this switch!

When I clipped the old spade connector off the wire it was obvious the wire was knackered, I clipped it back a bit more but the copper inside was still in bad shape. I got some heat resistant 3 core oven wire and took one of the wires out of this, and put the spade connectors on each end. Fitted the new switch and everything is working fine. Hopefully it lasts this time. Many thanks for your help
