This morning l was woken by the smoke detector, l couldnt see any smoke but there was a horrible burning smell... I couldn't find anything that was burning inside or out, then i thought l saw a slight bit of smoke from the top of the microwave, when i opened it the polystyrene foam was smouldering, l took it outside and hosed it, and turned the power off. Has anyone had anything like this happen? We've never used the microwave, we use it to store our bread normally, and l was up at 4.30am rolling the awning in because the wind had picked up and didnt notice anything wrong.
