Why is the green light flashing in my fridge?

[Primroseoil]

By accident I switched off my fridge on the inside when I put food in, now the green light has started flashing & I can't hear the hum😭

It means the milk is about to go off. It would be a good time to make custard.

Turn the inside thermostat back up and you will then hear the hum! You will need to turn it to a higher setting than before if the fridge has warmed up.

Thanks for the replies, all up & running again!
