Hope Someone can help?
My Kenwood CK414 cooker keeps tripping the RCD in the fuse box after it been on for around 15-20min. It happens when the top element and fan element are switched on, i’ve done resistance and insulation on both elements and they seem to check out ok, both greater than 1000Meg ohms at 500V test and resistance of each element around 23ohms. The only thing i can think is either element is failing under load or something else is causing it?
If anyone has got an suggestions to what could be causing this it would be much appreciated.
