So recently my oven stopped working. First thing I did obviously was letting it cool down unplug it to check if there weren't any obvious burnt components and reverse the thing.
But the issue is. It works for a little while(always) and then when the oven is heated up a little bit the earth leakage protection kicks in.
I tried to swap the live and neutral around and it didn't do much at all.
There's two big heating elements, the fan motors are both brussless (checked bearings, was still fine imho).
The main function switch is mechanical rotation switch like this;
I measured the heating elements and they where like sth between 60 and 30 ohms. 60 for the big one and 30 for the smaller one.
I called the company to verify any of my measurements but they don't tell it nor give the schematics or datasheet of the elements, nor can I find them online or by resellers.
What I tried was to measure the casing to the element terminals and there should not be any leakage resistance, and in my case it was only a few k ohms.
Any tips on how to properly test or measure the elements to make sure that they are bad or almost faulty. Because I don't feel like wasting 150 euros on elements if they are still fine.
The wierd thing is, it works for a small amount of time before it shorts. Maybe I can trace back the wires and look what happens because then the function switch was set to a cretain position "heated air function" after it failed the live and neutral where both dead shorted and when I switched back to another mode the short disappeared..
I called the company for more info, they could not give it but the nice guy in the technical support told me this is because dumb (he didn't directly say that, I made that of it but he agreed) people mess it up thus far that the oven burns down their house and the damage claim will be on them. Obviously I can completely understand this, and their reason for not giving it. But it still sucks to some point, if I knew what the elements should have had resistance wise I would have been able to easily say hey this is not good or otherwise and dig deeper down the rabbit hole.
