Troubleshooting:

If your refrigerator sounds like it’s straining, make sure the condenser coils are clean, that there’s at least one inch between the fridge and the wall for adequate air flow, and that the gasket (door seal) is not dry or cracking.

Dishwasher

Make-it-Last Habit:

Adhesives from jars of jelly or pasta sauce can clog the filter and hose. So can the oils and dirt from things like gardening and painting tools. And it may sound obvious, but don’t put non dishwasher-safe items in the dishwasher—you could damage the item, yes, but you may also harm the machine.

Troubleshooting:

Use a dishwasher cleaner, like Affresh ($9; amazon.com), every 30 uses or so. The tablet’s ingredients break down mineral deposits and help dislodge food residue.

Oven

Make-it-Last Habit:

Keep a baking sheet on the lower rack to catch spills. If food splatters, scrape it off with a spatula after the oven cools. Coat big spills with salt while the mess is hot. The next morning, you’ll be able to scoop up the salt pile without breaking a sweat.

Troubleshooting:

Moisture buildup on the inside of the oven’s glass panel means the seal has been compromised. Check the owner’s manual to figure out what kind of replacement gasket to buy. The fix should take just minutes.

Microwave

Make-it-Last Habit:

Clean up spills as soon as they happen. Grime, grease, and food particles can gunk up the machine and shorten its life span. Once a week, wipe down the door seal, frame, and control panel using a cloth dampened with all-purpose cleaner. Or try this easy cleaning method.

Troubleshooting:

If your microwave is acting up, visit repairclinic.com to help diagnose the problem. Enter your model number in the Repair Help section of the site and look at the list of symptoms (buttons don’t work, turntable doesn’t rotate) to learn the most likely cause of the issue and how to fix it.

Washer

Make-it-Last Habit:

Keep the door open between cycles to help it fully dry and to avoid mold growth.

Troubleshooting:

If your machine is rocking or vibrating, make sure it’s level. The legs on most models are adjustable, but at least two people are needed to adjust them safely.

Dryer

Make-it-Last Habit:

Overloading the dryer is one of the quickest ways to shorten its life span, so follow the manual’s guidelines on load capacity.

Troubleshooting:

If clothes take longer than 60 minutes to dry, lint is likely clogging the venting system. Remove stubborn residue from the lint filter with a bristle brush, and replace the filter if you see any rips or holes. Use the hose attachment on your vacuum to clean out the lint screen housing. Once a year, remove the aluminum vent pipe from the dryer’s rear and clean out lint or foreign objects with a 20-foot-long dryer vent cleaning brush (Cleaning Brush 18001034, $41; repairclinic.com). While you’re at it, unplug the machine, remove the lower front or back panel, and vacuum out the dryer cabinet.
