How to Check the Lines on a Freezer

Pull the fridge out from the wall and check the rear backside of the unit, or in some cases, you’ll need to tip the unit backward carefully to look at the underside. Check each area for a network of thin copper-colored piping – these are the refrigerant lines. Some models feature the same network of tubes encased underneath a plastic insulating panel. In cases such as these, you’ll need to remove the panel with either an appropriately sized Allen wrench or a Phillips head screwdriver.

Open the freezer door and look along the hinge-line where the door opens if the above didn’t help you locate the coolant lines. Some fridge manufacturers line the opening around the door with coolant tubes but these lines are generally only accessible by removing the rubber seal that line in the interior of the opening. Coolant lines are never actually located on the door’s interior so there is no need to remove the seal from the door itself.

Look at the plastic interior that covers the entirety of the fridge compartment’s interior. If it’s iced over, you’ll need to unplug the unit and prop the door open to allow warm air to melt the ice in order to gain access to the plastic covering. Place plenty of towels on the floor around the open freezer to sop up water. Once the ice is out of the way, you’ll need to remove each set of four holding screws on each panel to gain access to the fridge lines underneath.
