Common Appliance Problems You Can Fix Yourself (And When to Call a Pro)

Not every appliance problem requires a service call. Some issues have simple solutions you can handle yourself in minutes. But other problems are best left to professionals—for safety reasons or because DIY attempts can make things worse. Here is how to tell the difference.

Washing Machine Problems

DIY: Machine Will Not Start

Before assuming the worst, check the basics. Is it plugged in? Is the door fully closed and latched? Many washers will not start if the door sensor does not register a secure close. Also check if the outlet works by plugging in something else.

DIY: Washer is Vibrating Excessively

Check if the machine is level—adjust the feet until a bubble level shows even. Also make sure you have not overloaded the drum or washed a single heavy item (like a comforter) without balancing items.

Call a Pro: Not Draining or Spinning

While you can check for kinked drain hoses or clean the pump filter (if accessible), persistent drainage issues often involve the pump, lid switch, or control board—repairs that require expertise.

Dryer Problems

DIY: Clothes Taking Forever to Dry

This is almost always a ventilation issue. Clean the lint trap, then check the exhaust vent outside your home. Pull the dryer away from the wall and inspect the vent hose for kinks or blockages. A clogged vent is a common cause—and a fire hazard.

DIY: Dryer is Noisy

Check for coins, buttons, or other objects in the drum. Also look for items caught between the drum and the door seal. If the noise persists, it could be worn drum rollers or a belt—that is pro territory.

Call a Pro: No Heat at All

For electric dryers, this could be a blown thermal fuse, faulty heating element, or thermostat issue. For gas dryers, it might involve the igniter or gas valve—definitely not DIY territory.

Refrigerator Problems

DIY: Fridge Not Cold Enough

Check the temperature settings—someone might have accidentally bumped them. Clean the condenser coils (dusty coils reduce efficiency). Make sure vents inside are not blocked by food items and the door seals are clean and sealing properly.

DIY: Ice Maker Not Working

Check that the ice maker is turned on (there is usually a switch or arm). Make sure the water line is not kinked behind the fridge. Replace the water filter if it has been more than 6 months.

Call a Pro: Fridge is Warm and Running Constantly

If your fridge is warm despite running non-stop, you likely have a sealed system issue (compressor, refrigerant leak, or evaporator). These require professional diagnosis and repair—and sometimes refrigerant handling certification.

Dishwasher Problems

DIY: Dishes Not Getting Clean

Clean the filter (usually at the bottom of the tub)—food debris clogs it over time. Check that spray arms spin freely and their holes are not clogged. Use a dishwasher cleaner monthly. Also, run hot water at your sink before starting to ensure the dishwasher begins with hot water.

DIY: Dishwasher Smells Bad

Clean the filter, wipe down door seals where gunk accumulates, and run an empty cycle with white vinegar or a dishwasher cleaner. Food debris trapped in hard-to-see places is usually the culprit.

Call a Pro: Dishwasher is Leaking

A small amount of water under the door could be a worn gasket (sometimes DIY-able). But leaks from underneath often involve the pump, hoses, or inlet valve—and water damage can escalate quickly. Best to get professional help.

When to Always Call a Professional

The Bottom Line

Knowing which problems you can handle and which need a pro saves you time, money, and frustration. When in doubt, it is better to call for help than to turn a small problem into a big one. We have seen plenty of "quick fixes" that ended up costing more than the original repair would have.
