Yes, but you have to do it directly before putting it in the oven. As far as what a trivel is, you might just want to google that one. chances are that might not be the right spelling.
Please only attempt to do this if you think that you aere competent to do so.
First always remove the plug from the mains socket.
Induction cookers virtually all use the same electronics. Here is a video site that claims to show how to repair an E3 fault, though I have not tried to repair this fault.>>>

The sensor is available on ebay. Type in "induction cooker thermistor" and you should be able to match it to the correct sensor. You should also need some "thermal paste", type this into ebay and select the cheapest available, they are all the same.
. The only tool required is, I think, is a No 2 Phillips screwdriver.
