Install a refrigerator water filter to remove the bad taste from drinking water and ice cubes. An inexpensive inline refrigerator water filter reduces chlorine, rust, sediment and odors for water- and ice-dispensing refrigerators. Filters are available from home centers and appliance stores. The filter splices into the standard 1/4-in. copper or plastic refrigerator water supply line. Locate the filter as close as possible to the water shutoff valve. Leave at least 6 in. of clearance between the wall and refrigerator when installing the filter behind a refrigerator. Once you install the system, quick-connect fittings make it easy to change the filter. Turn off the shutoff valve and disconnect the 1/4- in. supply line from the valve (hold a bucket under the valve to catch residual water). Some types of valves leak. You may have to turn off the main water supply valve to your home. Cut back the tubing and attach the quick-connect fittings. Snap the filter into the fittings. Secure the tubing on the fridge side with a 1/4-in. copper strap and flush the filter to dispense any fine loose carbon particles. If a leak occurs, tighten the nuts or fittings. Strap the filter to any nearby support to take stress off the tubing. Write the installation date on the filter and replace it every six months with a new one.

Straighten Sagging Refrigerator Doors

Straighten a crooked fridge door in less than five minutes. You save money too by stopping cool air leaks around the door.

A sagging refrigerator or freezer door doesn't just look bad. It can cause the door gskets to seal poorly, and that means your fridge will work harder to keep the milk cold. It can also lead to frost buildup in the freezer. To realign the door, just pry off the hinge cap and loosen the hinge screws. Then align the door with the top of the refrigerator. Adjust only the top hinge to straighten an upper door. To realign the lower door, adjust the middle hinge. Moving the middle hinge will affect the upper door, so you may have to adjust the top hinge afterward.

How to replace the door gasket

Each door of your refrigerator has a molded rubber gasket to keep the cold in and the heat out. When this gasket gets old and brittle, it leaks. If your refrigerator is running more frequently and you suspect it's losing cold air, conduct these simple tests.

First, inspect the door gasket. Is there condensation or even blackish mold anywhere around it? If so, leaking cold air is probably causing warmer kitchen air to condense. Next, close the refrigerator door on a dollar bill. Pull the bill out slowly. If there is a slight drag on the bill, your door gasket is OK. If the bill slips out easily and moisture and/or mold are present, it's time to invest about $50 to $75 (depending on the appliance brand and door size) and 30 minutes to replace the door gasket.

Find the refrigerator make, model and other identification information in the owner's manual. If you don't have a manual, look on the inside edge of the refrigerator door or inside either compartment, near the door, for the manufacturer's identification plate. Search online or check the yellow pages under “Appliances, Major, Parts” for stores or manufacturer service centers that stock your door gasket. You may also be able to find a parts source by visiting your manufacturer's Web site.

While you're removing the old door gasket, lay the new one in warm water for a few minutes to make it easier to install. Some gaskets (like ours) are held in place by a metal retainer attached around the door perimeter. Lift the inside edge of the old gasket to reveal the screws locking the gasket into the retainer, then loosen them.

Remove the old gasket from the retainer. Starting at one of the top door corners and working out to each side, slip the lip of the new gasket behind the retainer. The gasket fits only the one correct way. Complete the gasket installation and “snug up” but don't fully tighten the retainer screws.

Study the position of the door relative to the other door and the refrigerator cabinet. If either the refrigerator or freezer door is sagging or too high, loosen its hinges and align it. Finally, reduce gasket drag by applying a thin layer of petroleum jelly only along the hinge side of the gasket.

Refrigerator problem? It could be the compressor  but before you call the repair service, try these simple repairs. The problem may just be a bad overload or compressor relay.

Try a new overload or compressor

Pull the fridge away from the wall, unplug it and remove the service panel. Swap in the

new compressor and overload relays. Then plug it back in to see if the problem is gone.

Fix a refrigerator water dispenser quickly and easily with standard hand tools and a new switch. You can do it in an hour.

Buy a replacement switch and remove the trim panel

So the kids were really thirsty and jammed their glass into the water dispenser on the refrigerator door. Now the paddle is hanging by a wire, and you’re seeing a $300 repair bill. No way! You can do this repair yourself with ordinary hand tools in about an hour. A replacement paddle/switch costs about $75. We’ll show you how to make the repair on a Whirlpool refrigerator. Repairs on other makes are similar.

Open the fridge door and write down the model and serial number of the fridge. Then contact a local appliance parts dealer or use the Internet  to buy a new switch and paddle.

Start by unplugging the refrigerator. Then remove the drip tray to expose the trim panel screws. If you don’t see any screws, unsnap the panel using a plastic putty knife and paint can opener . Lift the trim panel off the door.

Replace the broken switch

Next, remove the microswitch. The switch retaining pegs are usually broken, so replace them with screws. If the paddle is broken, first disconnect the water tube. Then remove the metal paddle retainer plate and swap in a new paddle.
