Understanding the Problem
The lint screen (lint trap) catches fibers and lint during drying. When it becomes clogged, torn, or the housing is damaged, airflow through the dryer is restricted — causing long dry times, excessive lint in the house, overheating, or lint buildup in the cabinet and vent. Below are step-by-step diagnostics and repairs you can do yourself. 1) SAFETY FIRST - Unplug the dryer or switch off its circuit breaker before any inspection or repair. If it's a gas dryer, shut off the gas supply before major disassembly. 2) QUICK INSPECTION & CLEAN - Pull out the lint screen and inspect it visually. If it’s full of felt, clean it by hand and then wash with warm soapy water if sticky residue remains. Let dry completely before reinstalling. Do not use water on metal mesh with electrical power on. - Check the screen frame for cracks or missing snaps. A damaged screen allows lint to bypass the trap. 3) CHECK THE LINT TRAP HOUSING - Shine a flashlight into the lint trap slot. Use a long-handled brush or vacuum hose to remove lint from the trap housing. Lint can accumulate deep inside the cavity and reduce airflow even with a clean screen. - If there is a visible gap or broken lip where the screen mates, the screen may not seal properly and should be replaced. 4) TEST DRYER AIRFLOW - With the dryer on (empty) and the door closed, feel airflow at the exhaust vent outside the house. Strong consistent airflow indicates the trap and vent are clear. Weak airflow indicates blockage in the trap, duct, or exhaust. 5) CLEAR THE EXHAUST DUCT - Disconnect the exhaust duct from the back of the dryer (after unplugging). Clean lint from the duct and the dryer’s vent outlet. Long vent runs, bird nests, or crushed ducts often cause the same symptoms as a bad screen. 6) LOOK FOR DAMAGE BEYOND THE SCREEN - If cleaning the screen/housing and vent does not restore performance, inspect the blower wheel for lint build-up, and ensure the motor spins freely. Inspect the heating element and thermostats if you have heat problems. 7) REPLACEMENT STEPS (STANDARD LINT SCREEN) - Unplug the dryer. Remove the old lint screen by pulling it out of its slot. If the screen is secured by screws or a retainer, remove those fasteners first. - If the housing is broken and you must replace the full assembly: open the dryer top or front (model-dependent). Typically this requires removing a few screws securing the top/front and lifting the panel. Remove the old housing and install the new one, securing with the original screws. - Insert the new lint screen and test: run the dryer empty and check airflow at the external vent and for normal operation. 8) FINAL CHECKS - Ensure the new screen sits flush and seals the housing. Reassemble any panels and restore power/gas. Run a test cycle and confirm drying times and that no excessive lint escapes the trap or vent. Safety note: Always unplug the dryer or shut off power before removing panels or working near the blower and heating element. For gas dryers, shut off gas at the supply valve before internal work. If you smell gas after reassembly or suspect a gas leak, evacuate and call a licensed technician or gas company.
Common Symptoms
Long drying cycles, excessive lint escaping into laundry area, lint collecting behind the dryer, dryer overheating or shutting off on high-heat cycles, burning smell, or dryer takes multiple cycles to dry clothes.
Common Causes
- Clogged lint screen (packed with lint or fabric softener residue)
- Damaged or warped lint screen frame that doesn't seal
- Lint built up inside lint trap housing or in the exhaust duct
- Broken lint trap housing or missing retainer causing bypass
- Restricted external vent or collapsed/blocked duct

Helpful Repair Tip
If cleaning the screen and trap restores strong airflow at the external vent, the screen/cleaning fixed the issue. If airflow remains weak after cleaning the trap and duct, the problem is likely a blocked exhaust duct, damaged trap housing, or a restricted blower — not just the screen.
Frequently Asked Questions
How often should I clean the lint screen?
Clean the lint screen after every load to maintain airflow and safety. Wash the screen with warm soapy water and let it dry if residue builds up — do this monthly or as needed. Also clean inside the trap housing and external vent every 6–12 months (more often for heavy use).
Can I run my dryer without the lint screen?
No. Running the dryer without a lint screen allows lint to enter the dryer cabinet and vent system, drastically increasing fire risk and reducing airflow. If your screen is missing, replace it before using the dryer.
