Refrigerator Door Gasket 

You can tell if your fridge door gasket/seal needs to be replaced if the fridge door isn't staying closed properly. Generally speaking if the door is shut and you can slip a £5 note between the seal and the door frame then it's time for a replacement.  Remember if your fridge has a faulty seal then it's using more energy than it needs to. This is a genuine spare part for select Whirlpool refrigerators. See the list of appliances to ensure compatibility.
