Hello I know this probably isn't the right forum to be posting this on generally but everyone here seems good with electronics and I was hoping someone could help.
My grandmother has an obession that she is going to leave her fridge door ajar, so much so that she bought an alarm to tell her when the fridge light was still on, this was fine as it repeated the message over and over again until the door was shut, however, it broke. So far we have pruchased two of the exact same thing and both of them play the message only once. so my question is, is there any easy way to modify the corcuit to make it repeat the message as it did with her previous one.
If at all helpful, here are some pictures
