cooker keeps tripping rcd

[bluematt1]

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.

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

Just wondered what "lock on and watch the reading rise" meant?

this can happen when you test when somthings in the circuit , when doing an IR test and a appliance is in circuit the readings can rise ,not a reccommended thing to do at 500 volts

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
