Hi Im pulling me hair out got a cooker that keeps tripping rcd not the trip it mainly happens once its had fan oven on for a while and when you want to check ya dinner ya open the door and it trips it doesnt have a light on it so it doesnt have a switch on door oven remains running when door open thats if its not tripped.
Its a Range type oven belling only 4 years old Ive had the back off and theres nothing obvious touching the chassis of oven it doesnt matter also if the non fan oven is being used ya can sometimes just lean on it and it trips even if the oven is switched off it does seem more heat related though.
Where oven is between units and mfi guy in my eyes mounted work tops to high the oven does sit on piece off board thats bonded in only 12mm just to make oven sit level with worktops and the feet on oven are course platic threaded rubbish things that screw into the thin bottom of oven and being 100cm wide there does seem to be an element of twist in chassis of cooker.
Im almost tempted to go buy anoter but there about £1000 and its only 4years old any views would be appriciated.
 
ring a local engineer who specialises in that type of oven!! as its probably a specialist area and not a bog standard argos brand..! sounds more oven related than Electrical installation
 
Could be an element shorting out , you will need to get the elements tested to find out which one
 
Hi,
"Its a Range type oven belling only 4 years old Ive had the back off and theres nothing obvious touching the chassis of oven it doesnt matter also if the non fan oven is being used ya can sometimes just lean on it and it trips even if the oven is switched off it does seem more heat related though."

if its tripping the RCD when you touch the oven when its turned off i would advise to get some electrical guy to have a look ASAP.
 
Get your tester out , disconnect from wall and basically pat test it do an IR test N to E then L to E ,but when you do the L to E tests repeat it and switch on each of the hot plates and oven / s , it sound like an element fault ,the elements on these are quite easy to change ,having said that if you have any doubt get a proffesional appliance serivce engineer in to repair it

Well I checked elements in ovens and grill look ok no signs of burning out I will do the N to E and L to E test with a meter the hobs are gas with spark igniter.
I was hoping someone would say Ive had that and its this but no such luck.
Im convident with a meter I work with car electrics only difference with 240v is it hurts/kills so remember to turn off power before touching

Had a problem similar to this many years ago and found the elements had become porus and where drawing in damp causing a short to earth. If you have and IR tester you can lock on and watch the reading rise would be the best way to check if this is the problem
 
think you ought to be checking the mains terminal block for a loose connection, could be causing this or in the ccu. is it tripping the cooker mcb or the rcd? if its the rcd, more likely to be a wiring fault rather than a cooker fault ( x service engineer) or it may indeed be the fan oven element breakikng down after being in use for some time, megger this to earth as well, wont be the fan motor these are double insulated.
 
you can't test for earth faults with a multimeter. they only put a few volts on. you need a 500v megger to find leakage
 
or a halogen oven. £39.99 off drop dead TV

Hi ung,

can you explain this please mate. How do you ir test it whilst it's on. I'm just trying to learn btw. Cheers mate
 
lost me as well
 
buy a microwave ... sorted... next...........

could be any loose connection but particulary around element

Far more fun with a camp fire , did you here about the guy who used his BBQ in the house because it rained yes you guessed ended up with no house the numpty

Telextric is right very difficult to locate a low resistance insulation fault with a multimeter , you do need an insulation tester ,and with these you need to be carefull you dont blow up any sensitive electronics in the appliance . it could anything from a stat to an element , without the proper test equipment may be an impossibility to find
 
first dis. the cooker completely and IR the wiring from CU to cooker otlet. if this is ok, then you know it's the cooker.
 
check the fan
they give probs
also check the wiring inside i have seen a few bellings awful stuff like a kids wired it
if it has a rotary switch for the heat setting/elements have a good looke they are rubbish and the metal used is nasty stuff the blades go soft and arc
