help cooker switch tripping

facingthefuture

Hiya, normally I would ask my dad questions like this but he passed away so I don't know what to do.
I plugged in something electrical which caused the power to trip. Electrical fiendish device is now being recycled BUT now our cooker switch won't stay on (the big one with the red light on the wall). I changed the 30amp fuse in the fuse box marked 'cooker', still no luck. Second I turn it on, power trips. Obviously I will call an electrician if necessary but if it's something silly - can anyone tell me? It would be really appreciated.

Sorry to hear about your dad. Sounds like it's likely something with your cooker, or the wiring, but I think it's going to be difficult for anybody to remotely diagnose without any details.

Difficult to diagnose without seeing it. However, this happened after you'd plugged something in to the socket ? Is it one of those where it's a socket and the cooker switch together ? If so, it's possible that the plugged-in item has caused damage to the socket/switch.


The easiest thing to do is check this. Start off by switching off the power at the mains - this part is VERY IMPORTANT !!!!


Now remove the face-plate from the switch/socket, and have a look. Are all the wires seated securely into the terminals ? Is there any sign of shorting/arcing ( blackened wires or plastic ) ? If any of the wires are loose, then re-seat them. If it looks like something has shorted and burnt something, buy a new faceplate from B&Q or wherever and refit it.


This would be the simplest thing to check first. If it's not that then my money would be on a fault within the cooker somewhere, and that's not something I could diagnose without looking at it.

Unless it's a cooker switch with a built in 13A socket where you plugged in the 'fiendish device', there should be no connection, since a cooker circuit will be a dedicated radial circuit serving only the cooker. The other 13A sockets will be on a separate ring mains circuit. Please confirm.
If both circuits are tripping out, then this suggests that you have an RCD on the CU that protects both these circuits, and that possibly that RCD is faulty.
Is the board fitted with MCB's or RCD's? The latter are the ones with test buttons fitted to them.
If the cooker circuit alone is tripping out then there is a fault on the appliance, switch or cable causing earth leakage, and you need to get a sparky in.

OP says that "I changed the 30A Fuse" suggesting it is not RCD or MCB.
