If your fridge or freezer door has a seal that is warped or doesn’t fit flush to the door, this can result in a flow of room temperature air inside the appliance. Over time this air causes the fridge or freezer to ice up, starting at the point the air enters through the seal. If the ground underneath your fridge or freezer is not flat, the insides of the appliance could become warped resulting in a misaligned door and gaps in the seal. This is another common cause of air flowing into the fridge or freezer producing over icing and frost build-up. A solution to remedy this problem would be to make sure the appliance is level using a spirit level and adjusting the feet to compensate. One way to check the seal on a fridge or freezer is by holding a sheet of paper so it’s held just in-between the seal and the doorframe, close the door and if it falls out or moves then it’s likely that the seal is warped or damaged. Sometimes the fridge door seal can become distorted over time with general wear and tear. On some fridges the seal can be replaced but you’ll find that on particular brands of fridges & freezers you’ll have to replace the entire door. One trick you can try is using a hairdryer to heat the seal and mould it back into the correct shape. Make sure you close the door and allow the seal to cool once you have it in the correct position. Always remember to defrost your fridge after reshaping a door seal. A common cause of a fridge seal splitting is opening the door without using the handle. If the door is pulled from the edge a fingernail can knick the seal and cause a split. It is very important to replace the door seal if it has split on the side that makes the connection to the frame.
