Oven tripping RCD when turned off

Anonymous user 07/03/2024 - 3.32 PM

Every time I turn my oven off, after it cools down or during cool down it tripe the RCD on the fuse box. Heating element was replaced 2 years ago as oven wasn’t heating up now this problem. But when I turn the oven off by isolator switch then turn the oven off it doesn’t trip and even when I turn off the top oven as normal, it doesn’t trip. Spoke to few electricians and they say they never come across this problem. Can anyone help. I don’t want get a new oven and problem continues or do I just turn off oven by isolator switch after using oven (don’t use oven as much as use air fryer)

Are you a tradesperson and able to answer this question?

Hi Jan, It sounds like Earth leakage is tripping the RCD, it’s likely a fan in the oven has a motor and they often cause earth leakage current when switched off. Usually it’s not enough to trip the RCD 30Ma but you could have other equipment with small Earth leakage and then the oven just puts it over, or it could be the motor of the fan deteriorating as it ages. I assume you have a Dual RCD Fuse-board and one option is to reconfigure the Fuse-board so that the oven is on its own RCBO.

You need to change the element in oven maybe fan but in my experience the most common cause is element failure

It could be one of the elements leaking when it gets hot. I had this on an oven years ago. Under the 16th edition, I never put the oven on the RCD side of the consumer unit because of this.
