How to Install Dryer Seal Transition Duct WP8566209 in a Whirlpool Dryer
Quick answer: Unplug the laundry center, pull it from the wall and remove the dryer's rear access panel. Unscrew the transition duct from the blower housing, strip off the old seal, clean the flange and press WP8566209 onto it. Refit the duct, reconnect the vent and confirm strong airflow at the outlet.
On a Whirlpool laundry center the dryer sits on top of the washer, and its blower pushes hot, damp air down through a transition duct to the exhaust outlet at the back. Seal WP8566209 is the foam gasket that closes the joint between the blower wheel housing and that duct. When it crumbles, part of the airflow escapes into the cabinet instead of going outside. The symptoms are long drying times, a warm and humid cabinet, lint collecting around the back of the unit and, on some models, repeated tripping of the high-limit thermostat.
Replacing the seal is not difficult, but the access is what makes it a moderate job: on stacked units such as the YGEW9200LQ0, the CEP2760KQ1 or the Kenmore 11072062100 you work from the rear, so the machine must come away from the wall. Plan for a helper if the laundry center is in a tight closet. Once the rear panel is off, the actual seal swap takes only a few minutes.

- Unplug the laundry center before removing any panel; a stacked unit has one cord that feeds both machines.
- If the dryer is gas, turn off the gas valve behind the unit before moving it and check for leaks with soapy water afterward.
- Wear gloves. The blower housing, duct edges and cabinet flanges are sharp stamped metal.
- Move the unit with two people. A laundry center is top-heavy and can tip forward.
- Vacuum lint from the blower area before working; loose lint near a heater is a fire risk.
Tools and Parts You Need
- 1/4-inch nut driver or socket for the rear panel and duct screws
- Phillips screwdriver
- Flashlight or headlamp
- Vacuum with a crevice tool for lint
- Rubbing alcohol and a rag
- Plastic scraper for old foam
- Work gloves
- Foil tape for the exterior vent connection
Step-by-Step Installation
- Disconnect power and utilities Unplug the cord. For a gas dryer, close the gas shutoff. Turn off the washer water valves as a precaution since you will be pulling the whole unit forward.
- Pull the unit away from the wall Walk the laundry center forward about two feet so you can stand behind it. Disconnect the flexible exhaust vent from the dryer outlet by removing its clamp or tape.
- Remove the dryer rear access panel Locate the panel behind the dryer section. Remove its screws with the nut driver and lift it off. Set it aside with the screws in a cup.
- Find the blower housing and transition duct Shine the light toward the lower rear of the dryer. The blower housing is the round cover on the motor; the transition duct is the sheet metal channel that runs from it to the exhaust outlet. The old seal is at the joint between them.
- Detach the duct Remove the screws holding the transition duct to the blower housing flange and, if needed, the screws at the exhaust outlet. Ease the duct off. Vacuum lint from the duct and the blower housing while they are open.
- Strip the old seal Peel away every trace of the old foam from the flange. Scrape stubborn pieces with the plastic scraper, then wipe the flange with alcohol so it is clean and dry.
- Install WP8566209 Place the new seal on the blower housing flange in the same position the old one occupied, with the sealing face toward the duct. If it has adhesive backing, press it down evenly all the way around. Do not stretch it to fit.
- Reattach the duct and vent Set the transition duct back onto the flange so the seal is compressed evenly and drive the screws snug. Refit the exterior vent hose, secure it with the clamp or foil tape, and reinstall the rear panel.
- Test airflow Push the unit back, restore power and gas, and run the dryer on air fluff. Hold your hand at the outside vent hood; you should feel a strong, steady stream. Check that no air is leaking from the rear of the cabinet.
Fit Checks Before You Call the Job Done
- The seal sits fully on the flange with no gaps or overlaps at the ends.
- The transition duct is squarely seated and all its screws are tight.
- No lint is left inside the blower housing or duct.
- The exterior vent hose is secured and not crushed behind the unit.
- The rear panel is refitted with every screw and lies flat.
Common Mistakes to Avoid
Reusing crumbled foam A half-disintegrated seal leaks nearly as much as no seal. Remove all of it before fitting the new one.
Skipping the lint cleanup Lint packed in the duct is often the real reason the dryer runs long. Vacuum everything while you have access.
Kinking the exhaust hose Pushing the unit back too hard folds the flexible vent and restricts airflow, which mimics the original problem.
Working on a gas unit with gas on Moving the unit can stress the gas line. Shut the valve first and check fittings with soapy water after.
Forgetting the washer hoses Pulling the laundry center forward without checking hose slack can strain the fill hoses and cause a leak later.
Troubleshooting After Installation
Drying is still slow Check the full length of the exhaust path outside the dryer; a blocked vent hood or crushed hose restricts airflow regardless of the seal.
Warm air leaks inside the cabinet at the rear The duct is not compressing the seal evenly. Loosen the duct screws, reposition and retighten.
Rattling noise from the back after reassembly A duct screw was left out or the rear panel is loose. Recheck every fastener.
Burning smell on first run Lint disturbed during the repair is landing on the heater. Run air fluff for a few minutes; if the smell persists, unplug and inspect the heater box.
Care Tips After the Repair
- Clean the lint screen after every load; a clogged screen forces air out through weak seals.
- Vacuum the exhaust vent and outside hood at least once a year.
- Keep a few inches of clearance behind the laundry center so the vent hose is never crushed.
- If drying times creep up again, check the vent path before suspecting another seal failure.

Frequently Asked Questions
Which machines use WP8566209?
It is listed for Whirlpool-built laundry centers including the YGEW9200LQ0, CEP2760KQ1, GGQ8821LL1 and Kenmore models such as 11072062100 and 11064996300.
Can I use generic foam weatherstrip instead?
Hardware store foam is not rated for dryer exhaust temperatures and can shrink or shed. Use the OEM seal.
Do I have to separate the dryer from the washer?
No. The blower and transition duct are reached through the dryer's rear access panel with the unit still stacked.
How do I know the seal was the problem?
Before the repair, look for lint build-up and moisture inside the rear of the cabinet around the duct joint; that pattern points to a failed seal.
