Clean the entire exhaust vent system when replacing the duct trap assembly—lint buildup is the #1 cause of dryer problems. If your old duct trap assembly was clogged with lint or damaged, the external exhaust vent hose and ductwork are almost certainly clogged with lint as well. Installing a new duct trap assembly without cleaning the entire vent system will cause the same problem to recur within weeks or months. Before installing the new assembly, disconnect the external vent hose and clean it thoroughly using a dryer vent cleaning brush or vacuum. If possible, clean the entire vent ductwork from the dryer to the exterior vent opening. Professional dryer vent cleaning costs $150-250 but prevents fires and extends dryer life. A clogged vent system causes 90% of dryer performance problems and is the leading cause of dryer fires.
Verify the duct trap assembly doesn't interfere with drum rotation before closing the dryer. After installing the new duct trap assembly, manually rotate the dryer drum by hand (with power disconnected) to ensure the drum rotates freely and doesn't rub against the duct trap. If the drum rubs or binds, the duct trap assembly may be mispositioned or the wrong part. Reposition the assembly and verify proper clearance. Operating the dryer with the drum rubbing against the duct trap causes excessive wear, noise, and potential damage to both components. Always test drum rotation before restoring power.
The duct trap assembly is the most common source of lint buildup—clean it every 6 months. Even with a new duct trap assembly, lint will accumulate inside the duct over time. Every 6 months, remove the front panel and inspect the duct trap assembly for lint buildup. Use a lint brush or vacuum to clean out any accumulated lint. A clean duct trap maintains maximum airflow and prevents dryer overheating. Professional technicians recommend cleaning the duct trap assembly twice per year, especially for households that do frequent laundry. Lint buildup reduces airflow by 50-70%, causing clothes to take 2-3 times longer to dry and increasing energy costs.
Check the lint screen for damage when replacing the duct trap assembly. The lint screen sits in the duct trap assembly's support frame. If the lint screen is torn, warped, or damaged, it won't capture lint effectively and lint will escape into the duct trap and exhaust vent. Before installing the new duct trap assembly, inspect the lint screen for damage. If the screen is damaged, replace it ($15-25) at the same time as the duct trap assembly. A damaged lint screen combined with a new duct trap assembly still allows lint to escape, causing the same problems.
Verify the exhaust hose connection is airtight—air leaks reduce dryer performance. After reconnecting the external exhaust vent hose to the new duct trap assembly, verify the connection is airtight. Run the dryer and feel around the connection for air leaks. If air is escaping, tighten the hose clamp or use foil tape to seal the connection. Air leaks reduce airflow efficiency by 20-30% and allow lint to escape into the dryer cabinet or laundry room. An airtight connection ensures maximum airflow and prevents lint accumulation.
The duct trap assembly is made of plastic—handle carefully to avoid cracking. The WW02F00669 duct trap assembly is made of heat-resistant plastic that can crack if dropped or handled roughly. During installation, handle the assembly gently and avoid overtightening mounting screws. Excessive force can crack the plastic housing, causing air leaks or structural failure. If the assembly cracks during installation, it must be replaced—cracked assemblies cannot be repaired and will cause airflow problems.
Different dryer models use different duct trap configurations—verify compatibility before ordering. GE dryers manufactured over different years use different duct trap assembly designs. The WW02F00669 replaces older versions (WW02F00418, WW02F00594, WE14X20617) but may not be compatible with all GE dryer models. Verify your exact dryer model number and compare the old duct trap assembly part number before ordering. Installing an incompatible assembly causes poor fit, airflow problems, or interference with other components. Check your dryer's model/serial plate and cross-reference with the manufacturer's parts diagram.
Inspect the blower wheel when replacing the duct trap assembly. The blower wheel (fan) is located near the duct trap assembly and is responsible for pulling air through the dryer drum and pushing it out the exhaust vent. If the blower wheel is clogged with lint or damaged, replacing the duct trap assembly won't fix the airflow problem. While you have the dryer disassembled, inspect the blower wheel for lint buildup or damage. If the blower wheel is clogged, clean it using a lint brush or vacuum. If the blower wheel is damaged (cracked blades, broken hub), replace it ($40-80) at the same time as the duct trap assembly.
