Refrigerator Maintenance Tips
Your refrigerator runs every day, so simple maintenance can help with cooling performance, water quality, and energy use. Start with the basics: keep the doors sealing properly, avoid blocking airflow inside the refrigerator, and replace the water filter when needed.
Replace the Refrigerator Water Filter
If your refrigerator has a water dispenser or ice maker, the water filter should be replaced regularly. Many homeowners replace refrigerator water filters about every 6 months, but usage and water quality can affect timing.
Signs you may need a new refrigerator water filter include:
- Water tastes bad or smells unusual
- Water flow from the dispenser is slow
- Ice cubes are smaller than normal
- The refrigerator filter light is on
- You cannot remember the last time the filter was changed
Always match your refrigerator water filter by model number, filter number, or approved replacement number. Filters are not universal, even if they look similar.
Shop refrigerator water filters
Check the Refrigerator Door Gasket
The refrigerator door gasket helps seal cold air inside the appliance. If the gasket is cracked, loose, dirty, or not sealing properly, the refrigerator may run longer than normal or have trouble maintaining temperature.
Wipe the gasket with mild soap and water, then check for tears, gaps, or hardened areas. If the gasket is damaged, it may need to be replaced.
Shop refrigerator door gaskets
Replace Refrigerator Light Bulbs When Needed
If the refrigerator still cools but the inside light does not turn on, the bulb may be burned out. Some refrigerators use standard appliance bulbs, while others use LED light modules. Search by model number before ordering a replacement light bulb or LED assembly.
Dishwasher Maintenance Tips
Dishwasher maintenance helps reduce odors, cloudy dishes, poor cleaning, and drainage problems. A dirty filter or clogged spray arm can make a dishwasher seem broken even when it only needs cleaning.
Clean the Dishwasher Filter
Many dishwashers have a removable filter at the bottom of the tub. Food particles, grease, labels, and debris can collect in the filter and affect washing performance.
Common signs of a dirty dishwasher filter include:
- Dishes come out gritty or dirty
- Water remains in the bottom of the dishwasher
- The dishwasher smells bad
- Food particles are left on dishes
- The dishwasher sounds louder than normal
Remove and rinse the filter according to your dishwasher owner’s manual. Reinstall it correctly before running another cycle.
Check the Dishwasher Spray Arms
Spray arms need to spin freely and spray water through small openings. If those holes are blocked by food, mineral buildup, or debris, dishes may not get clean.
Spin the spray arms by hand to make sure they move freely. Clean clogged spray holes carefully and make sure dishes are not blocking spray arm movement.
Washer Maintenance Tips
Washing machines deal with water, detergent, lint, soil, and vibration. Regular washer maintenance can help prevent odors, leaks, drainage issues, and shaking.
Clean the Washer Drum and Dispenser
Detergent residue, fabric softener, body oils, and moisture can build up inside the washer. Run a washer cleaning cycle if your machine has one, and clean the detergent dispenser regularly.
Front load washers also need regular gasket cleaning. Wipe around the rubber door gasket and check for lint, coins, hair, or small clothing items trapped in the folds.
Inspect Washer Hoses
Washer fill hoses should be checked for cracks, bulges, rust, corrosion, kinks, and leaks. A damaged washer hose can cause water damage, so it is better to replace a questionable hose before it fails.
Check the Washer Drain Area
Some washers have a drain pump filter or cleanout area. If your washer is not draining well, stops mid-cycle, leaves water in the drum, or has a musty smell, check your owner’s manual to see whether your model has a drain filter that can be cleaned.
Dryer Maintenance Tips
Dryer maintenance is especially important because dryers rely on strong airflow to remove moisture from clothing. Lint buildup can cause long drying times, overheating, burning smells, and unnecessary wear on dryer parts.
Clean the Dryer Lint Screen After Every Load
Remove lint from the dryer lint screen after every drying cycle. If the screen is torn, warped, cracked, or no longer fits correctly, replace it.
Check the Dryer Vent Hose
The vent hose behind the dryer should not be crushed, kinked, clogged, or disconnected. Poor airflow can make clothes take longer to dry and may cause the dryer to run hotter than normal.
Check the outside dryer vent while the dryer is running. You should feel strong airflow. If airflow is weak, the vent path may need cleaning.
Listen for Dryer Noises
Squeaking, thumping, scraping, or rumbling sounds may point to worn dryer rollers, a belt, an idler pulley, or drum support parts. Catching dryer noises early can help prevent more damage.
Shop dryer belts
Shop dryer rollers
Shop dryer idler pulleys
Oven and Range Maintenance Tips
Ovens and ranges are exposed to heat, grease, spills, and food debris. Regular cleaning and simple inspections can help prevent odors, smoke, lighting problems, and poor cooking performance.
Replace Oven Light Bulbs Safely
If the oven heats normally but the inside light does not work, the oven light bulb may be burned out. Many ovens use heat-rated appliance bulbs or halogen bulbs behind a glass cover.
Always turn off power and let the oven cool completely before replacing an oven bulb. Use the correct oven-rated bulb for your model.
Shop oven light bulbs
Shop oven halogen light bulbs
Clean Spills Before They Burn On
Food spills, grease, and sugar can smoke, smell, or burn onto oven surfaces. Wipe up spills after the oven cools. Avoid using harsh cleaners on surfaces not approved by the manufacturer.
Check Range Knobs and Burner Parts
Loose, cracked, or missing range knobs can make burner controls harder to use. Gas burner caps and grates should sit correctly so the flame can burn evenly. Electric coil elements should sit flat and connect properly.
Shop range knobs
Shop burner caps
Shop surface elements
HVAC Thermostat Maintenance Tips
Your thermostat controls your home heating and cooling system. If the thermostat is not working correctly, the HVAC system may not turn on, may short cycle, or may not maintain the correct temperature.
Simple thermostat checks include:
- Replace thermostat batteries if your thermostat uses batteries.
- Make sure the thermostat is set to the correct mode: heat, cool, or auto.
- Check that the set temperature is above or below room temperature as needed.
- Keep the thermostat away from direct sunlight, drafts, and supply vents.
- Confirm compatibility before replacing a thermostat.
If you are upgrading to a programmable or smart thermostat, check whether your system needs a C wire and whether the thermostat supports your HVAC equipment type.

Warning Signs You Should Not Ignore
Maintenance helps, but appliances can still develop problems. Pay attention to warning signs before they turn into larger repairs.
- Burning smells from a dryer, washer, dishwasher, or oven
- Water leaking from a washer, refrigerator, or dishwasher
- Unusual grinding, squeaking, buzzing, or thumping noises
- Appliance trips the breaker repeatedly
- Dryer takes more than one cycle to dry clothes
- Dishwasher leaves standing water in the tub
- Refrigerator water dispenser becomes very slow
- Oven light cover is cracked or missing
- Thermostat screen goes blank or restarts often
If you notice these issues, stop and inspect the appliance. In many cases, a simple part replacement may solve the problem, but electrical, gas, or major mechanical issues should be handled carefully.
How to Find the Right Replacement Appliance Part
The best way to find the correct replacement part is to search by the appliance model number or the original part number. Many appliance parts look similar but do not fit the same way.
Common places to find appliance model numbers include:
- Inside the refrigerator fresh food section
- Around the dishwasher door frame
- Inside the washer lid or door opening
- Inside the dryer door opening
- Around the oven or range door frame
- Behind the lower storage drawer on some ranges
Write down the full model number exactly as shown. Letters, numbers, dashes, and version codes can matter when matching parts.
