My mom seems to think that both my toaster oven and microwave should be replaced!
I found out how to check my microwave for leaks: http://www.wikihow.com/Check-a-Microwave-for-Leaks
But I can't find anything on a toaster oven. Mine is a Hamilton Beech, and I have had it for at least 5 years. I use it about 4 times a week, and there are no problems with temperature,etc. I keep it clean.
What are the signs that it's time to replace it?
