From David Cope
The easiest way to check if the fridge light is really going out when the door is closed is simply to close the door and leave the fridge running for a couple of hours (Feedback, 3 December). Then open the door and feel the lamp housing. If it is warm, the door switch needs adjusting. If the lamp housing is cold – all is well.
Incidentally, if the light is on permanently it will cost about an extra £40 a year in electricity bills and replacement bulbs, so it really is worth checking.

Most mobile phones allow you to record short video clips. Start recording a video clip, put the phone in the fridge (lens side up) for a few seconds with the door closed, then remove from the fridge and play the clip.

I can only wonder how many people will record the inside of their fridge on reading this.
