Hi all. I've tried searching the forums to no avail, so please bear with me as I explain this problem.
We live in an old house, but one that has been recently rewired. It has an RCD unit in the passage with a red RCD marked 'main switch' which appears to cover all of the electrical circuits and a smaller RCD, labelled 'RCD circuit' next to it, covering 3 switches, namely shower, cooker and ring circuit. The ring circuit appears to cover all of the electrical sockets in the house.
I have a used fully electrical cooker of unknown vintage. The cooker is hardwired in to wiring which is connected to a on/off switch on the wall in the kitchen. I presume this to be the cooker circuit?
Sorry to be so basic, but it's this level of detail that has not come up when searching....
When first installed 18mths ago, all worked fine. All elements worked correctly, and the grill and oven operated correctly. Use of any combination of oven cooking elements didn't trip the RCD.
Over this 18mth period, although the oven and grill still operate correctly, three of the cooking elements now cause the small RCD circuit to trip when any of them are turned on, leaving only one small element available to be used. If it makes any difference, the element still available for use is the bottom right.
Any of these three cooking elements do not trip the 3 RCD circuit switch (shower, cooker, ring) immediately when turning on, but only when they reach a certain temperature (after 2 mins or so). The main red RCD switch does not get tripped and never has.
Each of the elements has worked within the last 18mths, and they have failed one by one. I have tested the smaller RCD circuit with the shower and ring circuit turned off to see if there was an overload when using the cooker as well, but use of any of the three cooking elements still trips the smaller RCD
Am I able to just replace the elements with new ones? My thought being that if they are all the same age, it may explain why they have all failed, one after the other, in such a short space of time?
Or could it be something else, which renders the cooker as scrap?
Your thoughts and opinions would be appreciated....
Ian
