How to prepare your dryer for heavy back-to-school laundry loads

Backpacks aren’t the only things that get heavier once school starts. Between after-school sports, weekend activities, and the everyday mountain of clothes, your dryer’s about to see more action than it has all summer. Give it a little pre-season tune-up so it can power through the laundry marathon without a single skipped beat.

Clean the lint screen (really clean it)

Pulling lint off the screen after every load is good, but it’s not the whole story. Over time, fabric softener and dryer sheets can leave behind an invisible film on the mesh. That coating blocks airflow, forcing your dryer to work harder. Reduced airflow can leave your laundry damp. It can also make the dryer overheat, which puts extra wear on internal parts and can even shorten the appliance’s lifespan.

The fix is simple: every so often, wash the screen in warm, soapy water, rinse well, and let it dry completely before sliding it back in place. Your dryer will thank you with faster, more efficient cycles.

Inspect and clean the exhaust vent

If your dryer feels like it’s dragging its feet, the vent may be to blame, not the dryer. Lint can—and will—sneak past the lint screen and accumulate in the hose, slowing airflow. That means longer drying times, higher energy usage, and in the worst case, a potential fire risk.

• Check for blockages: Unplug the dryer, disconnect the vent from both the appliance and the wall, and use a vent brush or vacuum attachment to clear it out.

• Don’t forget the outside: Head outdoors and make sure the vent flap opens easily and isn’t blocked by leaves, debris, or even a bird’s nest. If you find one, safely remove the nest before using the dryer again.

Taking a few minutes to clear the vent means smoother airflow, faster cycles, and one less thing slowing down your back-to-school laundry routine.

Check the drum seals

Heavy back-to-school loads are tough on felt drum seals. When those seals wear down or loosen, warm air leaks out and fabric edges can catch where the drum meets the front panel. If this happens, you can say hello to longer dry times and mystery snags.

• Unplug first: Safety first; unplug the dryer before you inspect anything.

• Spin-and-listen test: Turn the drum by hand. Scraping, rubbing, or thumping can point to a seal that’s shifted or worn flat.

• Look for wear: Check the felt around the drum opening (and, if accessible, the rear edge). Frayed felt, bare spots, gaps, or adhesive residue are all red flags.

• Watch for clues in the load: Threads or pet hair caught at the drum edge, lint streaks inside the cabinet opening, or heat that seems to escape around the door can signal a tired seal.

• Act before back-to-school season: If the seal looks rough or loose, replace it now so big, bulky loads don’t make the problem worse. A fresh seal keeps heat where it belongs and helps clothes glide smoothly.

Test the moisture sensor

If your dryer has an automatic cycle, the moisture sensor is the brains behind it. The sensor tells the machine when clothes are dry so the dryer can shut off. But when that sensor gets coated with fabric softener residue or lint, it can misread the load. That means laundry that’s still damp when the cycle ends, or clothes that are baked long past dry.

• Test it: Run a small load and see if the dryer stops shortly after the clothes are dry. If it keeps running or shuts off too soon, you might have a sensor issue.

• Clean it: Wipe the sensor bars with a soft cloth and a little rubbing alcohol to remove buildup.

Knowing what the sensor does and how to keep it clean helps you keep it and your dryer in shape.

Check the drum belt

If your dryer’s been squeaking, slowing down, or stopping mid-cycle, the drum belt might be on its last spin. This long, narrow belt wraps around the drum, motor pulley, and tensioner pulley, and when it wears out, the drum can’t turn the way it should.

• Inspect for wear: Unplug the dryer, remove the front panel or access panel, and look for cracks, fraying, or slack in the belt.

• Replace before peak laundry season: A fresh belt means fewer surprises when the back-to-school laundry piles start rolling in.

If you spot damage, replace the drum belt to keep your dryer running smoothly.

Wipe down the drum interior

Sports gear, damp towels, and the occasional forgotten snack wrapper can leave behind odors and residue inside the drum. A quick wipe-down keeps things smelling fresh and prevents unwanted smells from transferring to clean clothes.

Use: A mild soap and water solution on a soft cloth; skip the harsh cleaners that can damage the drum’s finish.

Dry: Wipe with a clean, dry cloth before running the next load to prevent moisture buildup.

If you find ink, gum, or crayon in the drum, clean it carefully without damaging the surface. Even after the sweatiest soccer practice, a clean drum keeps your laundry smelling fresh.

A little dryer TLC now can save you from slow cycles and last-minute laundry disasters once the school year is in full swing. Clean it, check it, and replace worn parts before the laundry piles up.
