How to Install Felt Seal WP31001747 in a Whirlpool Dryer
If your Whirlpool dryer is not working properly, the drum felt seal may be part of the problem. A worn felt seal can let hot air escape, allow clothing to catch near the drum edge, or make the dryer sound rough while it runs. How to Install Felt Seal WP31001747 is a job many careful DIY repair users can handle with time, patience, and safe steps.
The felt seal sits around the dryer drum opening. It helps close the gap between the drum and the front or rear bulkhead area. When that seal wears down, the drum may lose a smooth contact surface. Heat and airflow may also move where they should not.
This guide uses only the supplied part and model details. The part type is Felt Seal. The OEM number is WP31001747. The appliance is a Whirlpool dryer. Listed compatible models include ADE20N3V, ADE7000AYW, ADG7000AWW, CDE22B6V, and CDE22B6V.
Before you begin, confirm your dryer model and review the official Whirlpool support resources.
Before You Start
A dryer felt seal repair takes more care than force. You may need to open the dryer cabinet, support the drum, remove old adhesive, and seat the new seal evenly. The listed install difficulty is Medium. Plan on 30 to 60 minutes if the dryer opens cleanly and the old seal comes off without a fight.
You should not rush this repair. Felt seals must sit flat. If the seal twists, overlaps poorly, or has loose spots, the drum may rub, snag clothes, or leak air again.
Check your model tag before buying or installing any dryer part. The compatible models supplied for this article are:

Use the full model number from your dryer, not a guess from a sticker on a manual or receipt. Model tags are often around the door opening, inside the door frame, or on the cabinet frame.
For official owner information, use Whirlpool’s Product Help Library or Whirlpool Service and Support manuals page. Those pages can help you find safety notices and model documents.
What the Felt Seal Does
The felt seal helps the dryer drum rotate against a soft sealing surface. It fills the small gap around the drum edge. That gap needs control because the dryer moves air through the drum while clothes tumble.
When the felt wears out, the dryer may still run. That does not mean it runs well. A bad seal can cause heat loss, lint movement, rubbing, and poor drum support at the contact area. You may notice the dryer not working properly, even if the motor still turns.
A felt seal is not an electronic part. It does not control power, timer settings, or heat by itself. It supports airflow and drum contact. That matters because dryers depend on steady air movement. Poor sealing can hurt drying performance and can make other wear problems worse.
You should also inspect nearby parts while the dryer is open. Look at the drum edge, rollers or glides if visible, lint buildup, and any worn contact surfaces. Do not replace extra parts unless you identify real wear and confirm fit.
Signs Your Whirlpool Dryer Felt Seal May Be Bad
A worn felt seal can show up in several ways. Some signs are clear. Others overlap with vent, heating, or drum support issues.
Watch for these clues:
- Clothes snag near the drum opening.
- You see felt pieces inside the dryer.
- The drum edge looks rough or exposed.
- Drying takes longer than usual.
- Air seems to leak around the drum area.
- The dryer makes a scraping or rubbing sound.
- Lint collects in odd areas inside the cabinet.
- The dryer is not working properly after normal cleaning.
These symptoms do not prove the felt seal failed. A clogged vent, worn drum support part, damaged belt, or heating issue can also cause trouble. Use inspection before repair. You need eyes on the seal.
Safety First
Unplug the dryer before you open it. If your dryer uses gas, shut off gas supply before moving or opening the unit. Do not work inside a powered dryer. You can get shocked, cut, burned, or caught by moving parts.
Let the dryer cool before repair. Interior metal parts can stay warm after a cycle. Wear work gloves if cabinet edges are sharp. Keep screws in a small cup or tray so they do not roll under the dryer.
Do not bypass door switches, thermal parts, or safety devices. Do not test the dryer while panels are removed unless the official service procedure calls for it. For most home repairs, you should reassemble the cabinet before running a test cycle.
Move the dryer carefully. Do not crush the vent hose. Poor vent flow can make a dryer overheat or dry badly. After the repair, check that the vent is attached and not kinked.
Tools and Supplies
No special tool list was supplied, so use a basic repair setup. Your exact dryer design may need different drivers, so match tools to the screws you see.
Common tools and supplies:
- Phillips screwdriver
- Flat blade screwdriver
- Nut driver set
- Putty knife
- Work gloves
- Small container for screws
- Shop vacuum
- Clean rag
- Mild cleaner if needed
- Plastic scraper
- Dryer-safe adhesive if required by the part design
- Felt Seal WP31001747
Do not use random household glue unless the part instructions allow it. Dryers create heat and airflow. Wrong adhesive can fail, smell, or make a mess inside the drum area.
If your replacement seal comes with instructions, follow those instructions first. They may state adhesive use, curing time, and seal direction.
Confirm Fit Before Opening the Dryer
Do this step before you remove one screw. Match the part number WP31001747 to your dryer model using a trusted parts source or official model lookup. You have supplied model examples, but your full model tag controls the repair.
A dryer model can have extra letters or numbers after the main model string. Those details can matter. Never trim the model number to make a part seem correct.
Use this fit check:
- Find the dryer model tag.
- Write the full model number.
- Compare it with the part listing.
- Confirm the OEM number WP31001747.
- Inspect the new felt seal for damage.
- Check whether adhesive or clips are required.
- Read any instruction sheet in the package.
If the new seal looks crushed, torn, oily, or stretched, stop. A damaged seal can fail early.

Common Mistakes That Cause Repeat Problems
A felt seal repair can fail when small details get missed. Most repeat problems come from poor cleaning, wrong placement, or rushed reassembly.
Avoid these mistakes:
- Installing the seal over old adhesive
- Stretching the felt during placement
- Leaving a twisted section
- Creating a thick seam lump
- Using the wrong adhesive
- Running the dryer before adhesive sets
- Pinching door switch wires
- Forgetting to reconnect the vent
- Letting the drum sit off-center
- Ignoring worn nearby support parts
Do not treat the felt seal like trim. It is part of the dryer’s air and drum contact system. Placement matters.
Original Repair Decision Matrix
Use this matrix before you decide whether to repair now, inspect more, or stop and get help.
| What you see | Likely next move | Why it matters |
|---|---|---|
| Felt is missing, torn, or hanging loose | Replace the felt seal | Loose felt can snag and leak air |
| Felt looks dusty but intact | Clean and inspect more | Dirt alone does not prove failure |
| Drum edge has sharp damage | Stop and inspect deeper | New felt may tear fast |
| Dryer will not start | Check power and door switch first | Felt seal does not control start power |
| Dryer dries slowly with clean felt | Check vent and airflow | Vent restriction can mimic seal issues |
| Loud thump or heavy scraping | Inspect support parts | Felt may not be only fault |
| New seal does not fit the circle | Stop and verify part fit | Wrong fit can damage clothes |
This table saves time. It also keeps you from blaming the felt seal for every dryer symptom.
Why Dryer Airflow Still Matters
A new felt seal helps the drum seal, but airflow still must move through the dryer and vent. If the vent is clogged, crushed, or too long for the setup, clothes may still dry slowly.
Clean the lint screen before every load. Check the vent path after the repair. A dryer can have a correct felt seal and still perform poorly if air cannot leave the appliance.
Watch the outside vent hood during a cycle. You should feel airflow. If airflow seems weak, stop using the dryer until you find the cause. Lint blockage can create heat and safety risks.
Do not pack the dryer full. Heavy loads push hard against the drum seal area. They also slow airflow through clothes. Use load sizes your dryer can tumble freely.
When the Felt Seal Is Not the Main Problem
Sometimes the dryer not working properly has nothing to do with the felt seal. Use the symptom pattern to guide your next step.
If the dryer does not start, check power, door switch action, and controls before focusing on felt. A worn felt seal will not usually stop the motor by itself.
If the dryer runs but has no heat, the heating system or controls may need inspection. The felt seal can affect drying, but it does not create heat.
If the dryer makes a deep rumble, check drum support parts. A felt seal can scrape, but support wear often causes heavier sounds.
If clothes come out damp, check the vent, lint screen, load size, and heat. Poor airflow often causes long dry times.
Use repair logic. Match the part to the failure.
Maintenance After Installing the Seal
A felt seal should last longer when the dryer runs clean and balanced. You can protect the repair with simple habits.
Clean the lint screen before each load. Do not run the dryer with a damaged or missing lint screen. Lint can move into areas where it should not go.
Avoid overloaded cycles. Clothes need room to tumble. Heavy loads press against the drum edge and can wear seals faster.
Check pockets before drying. Coins, screws, and small metal items can damage felt and drum surfaces.
Listen after the repair. A new scraping sound, burning smell, or snagged clothing means you should stop and inspect.
Vacuum around the dryer every few months. Lint behind and under the dryer can feed poor airflow and heat buildup.
