Appliance Repair Questions? Ask a Technician for Answers ASAP
Good afternoon, welcome to the Technical section in JustAnswer; my name is ***** ***** I will help you today.Has this electrical supply been used before? Is this oven a replacement for another oven? _____If you receive a phone call offer, please ignore it - these are system generated and outside my control. My understanding is that you won't be charged if there's no phone call.
I'm still here, but please be aware that each expert is assisting many customers in parallel, which is how this is kept as a low cost service. Therefore, sometimes there are natural breaks between posts, however the topic won't be closed until your problem is solved._____I'll have a look at your photos now and will respond ASAP.
While I'm looking, please could you tell me if there's a label on the new oven that shows the terminal block and the allocation of terminals?
Please wait a moment - I'm typing my reply...
OK. I was about to say that it's highly unusual to have no markings and no label. Clearly the manufacturer hasn't made things easy for you, but you can now proceed, but unless you can see similar markings on your old oven you should be cautious.Please treat all colours with suspicion - unless you prove the supply with a meter, it's an assumption that brown is the live in the supply.Supply brown should go to the terminal marked 'L'.Supply blue should go to the terminal marked 'N'.Supply green/yellow should go to the remaining terminal.
Do you still have the old oven?
Please scour the old oven for a label that shows the terminal block connections. Also look on the terminals for markings.I didn't know how long ago you took that photo.
Yes I realise now, but at the moment of asking if you still have the oven I made no assumption whether or not you had it.
Do you still have the back panel for the old oven? If so, is there anything on the inside of that?
I'm just checking the Smeg manual...
There's nothing in the Smeg manual, as is often the case. Is there no indication at all on the plastic terminal block?
Do you need the oven to be operational tonight? If not, I have a suggestion that will result in being 100% certain of a completely safe connection.
Are you near a Screwfix? If so, you can click-and-collect a cheap but very good multimeter and test the supply. Click here.I will send you steps to test the supply with the multimeter.
I suggest that you don't put your faith in the inductive tester. The risk is possible to your safety, and also to the oven - if you damage it the warranty won't cover it.
The steps are:1. Power off at the isolator to the supply for the oven.I'm sure you've done this, and would do it, but missing out this step would be incompetent on my part.2. On the new oven, disconnect the orange spade connector and the blue spade connector, and tape those leads out of the way so that they can't accidentally fall and touch the terminal block.3. Connect the supply brown to the terminal marked 'L'.4. Connect the supply blue to the terminal marked 'N'.5. Connect the supply green/yellow to the remaining terminal.
6. Turn on the supply to the oven.7. Ensure that you have the multimeter leads connected with the black lead in "COM" and the red lead in "V". Set the multimeter to the 600 "V~" range.8. Hold the block probe to the Earth and the red probe to 'L' . Note the reading.9. Move the red probe to 'N'. Note the reading.10. Power off again at the isolator._____At step 8 you should read around 240 volts.At step 9 you should read around 0 volts.If you got the correct reading then you can leave those connections as they are, and reconnect oven orange to the left terminal and oven blue to the middle terminal, confident that you've got it right._____As for what the previous installer did, I can't comment on that. If they got it wrong, then it neatly illustrates my point about never trusting any colour, and never making any assumptions with electricity.
You're welcome. Thank you for your rating :-)
