Hi there,
I have a problem. I have a Smeg SUK92MBL5 double oven.
All of a sudden turning the large oven on (even just the grill, just the bottom element or even just the fan) trips the electrics. Meanwhile (and thankfully for my pizza last night) the small oven works fine (though I did have to cut my pizza in half)!
I guess my question is what should I do to either identify the problem or what part should I replace first?
I have a multimeter should I remove elements and check them? Or if there’s someone local, I’m happy to pay for a repair?
Thanks in advance for your white good wisdom.

Jim,
Just checking elements with a multi-meter will not be suffice, you will need to use an insulation tester.
What you have stated leads me to beleive that the culprit is other than the element/s that you suspect. Firstly I would be looking toward the oven thermostat and then toward the selector switch.
For reasons of eticate and safety we are unable to instruct you on how to do this and to advise you to click here to Find An Engineer

Thanks,
How would I go about testing the thermostat?
Could that still be tripping it when I have it set to fan only?
(I’m a Mechanical Engineer and am confident that I can keep myself safe.)

Re: Smeg Double oven -small oven ok, large oven trips electr
A thermostat either works or it doesn’t. A thermostat wouldn’t cause the RCD to trip either. And chances are on the defrost (fan only) it wouldn’t necessarily trip the RCD. In fact if it doesn’t you can be sure that it is purely an element at fault.
Now if you don’t know how to test an element then we can assume your electrical know how is a worry and seeking expert help the best way to resolve the problem.

I doubted it was the thermo
Fair enough, I did say mechanical, I guess I was trying to say I know how to make sure I don’t give myself a shock.
Would it be safe to say that, as I am running fan only, the elements are not likely at fault either?
Re: Smeg Double oven -small oven ok, large oven trips electr
I believe I already indicated that in my previous post.
If it trips only when heat is required then logic would suggest an element must be at fault. 😉
Re: Smeg Double oven -small oven ok, large oven trips electr
Sorry if I’m missing something but…
What do you actually think that it may be?
Re: Smeg Double oven -small oven ok, large oven trips electr
Really?…… An element, it must be an element at fault. Your challenge is to find out which one OR get someone in to do it for you. (Better Idea TBH) 😀
Re: Smeg Double oven -small oven ok, large oven trips electr
Sorry, I wasn’t trying to be funny.
I really thought that the element would be isolated front the circuit somehow when it was in fan only mode and as it trips then, I thought it must be something else. Why would a blown element trip an oven when it’s not in use?
I like a challenge and don’t mind getting into things a bit.

EXACTLY ! That’s what I’ve been trying to get across to you! Wo hoo!
Over to you now to decide your next move, locate the faulty element yourself or get someone in?
Re: Smeg Double oven -small oven ok, large oven trips electr
We’ll to be fair, my statement above is me reasoning that it would not be an element.
I”m not here to argue, just after a bit of advice, but you’ve hardly been clear. To paraphrase…
“It won’t be an element at fault, now you just need to find out which one?”
Doesn’t make much sense mate. Woo hoo to yoo too!

Look at the first statement that the op has made “All of a sudden turning the large oven on (even just the grill, just the bottom element or even just the fan) trips the electrics.” The fan doesn’t come on with the bottom element or the grill. The only things common to all three are Thermostat (if it is the earthed type, and it is happening on all selections), Selector switch, or wiring problem.
As for the thermostat not tripping an RCD, only did one on weds with that fault… It depends if the thermostat has an earth tag.
The selector selects the spoken elements individually… Since it doesn’t matter which setting is selected and the RCD trips on any of 3 settings using individual elements then I do not presume that it is going to be one of your elements

Jimathey has been given more than enough input now to sort it I would think George. Albeit having misinterpreted the help I tried to impart his way. I just hope I don’t lose any sleep over it. :rolls:
Re: Smeg Double oven -small oven ok, large oven trips electr
Martin,
I appreciate the advice, I really do, but you must see that there was a degree of ambiguity and contradiction in your advice. The change of tone to that of a derogatory nature was disappointing and my genuine attempt to clarify things was not met as intended.George,
As it turns out the issue was the bottom oven element, a short from the core to earth. I was surprised this caused a trip when the element was not being called upon but hey there you go. Thanks for your input and for your concern.Both,
People like you offer a real service to people all over the country (and further afield I’m sure) thanks.Cheers
Jim
