How to Replace WP37001142 Dryer Lint Filter on Whirlpool & Maytag Dryers — Step-by-Step

Your Maytag MDE4806AYW is taking forever to dry a load of towels. You've checked everything — the vent hose is clear, the heating element works fine — but then you pull out the lint filter and notice the frame is cracked along the edges or the screen mesh is torn. A damaged lint filter doesn't just slow drying times; it's a fire hazard that sends lint straight into your dryer's exhaust system.

The WP37001142 lint filter fits dozens of Whirlpool, Maytag, and Amana commercial and residential dryers. This replacement takes about five minutes with no tools required, but getting the right fit matters — this filter works with models like the MDE3706AYW, MDG308DAWW, and MDET446AYW series.

What You Need Before Starting

• Tools Required: None — this is a direct pull-and-replace part
• Repair Time: 3-5 minutes
• Difficulty: Beginner
• Parts Needed: WP37001142 lint filter (replaces 37001142, 40124401, 503627, AP6008778)

Before you order, verify your model number on the label inside the dryer door or on the back panel. This filter is specifically designed for commercial-style Maytag dryers and certain Whirlpool models with the vertical lint filter slot.

Safety First

You don't need to disconnect power for this replacement, but make sure the dryer is cool to the touch. If you've just finished a load, wait 10 minutes — the lint filter housing retains heat. Never run your dryer without a lint filter installed, even for a test cycle. Lint buildup inside the cabinet can ignite from the heating element.

Step 1: Remove the Old Lint Filter

Open the dryer door and locate the lint filter slot at the top of the door opening. Grab the handle of the old filter and pull straight up and out. If it's stuck, wiggle it gently side-to-side while pulling — years of lint buildup can create friction along the edges. Inspect the housing inside the slot for any lint accumulation that needs vacuuming out.

Step 2: Clean the Filter Housing

Use a vacuum hose with a crevice attachment to clean the lint filter cavity. Pay attention to the corners where the filter frame sits — lint compacts there and reduces airflow even with a new filter. If you see any grey dust or debris, that's lint that's been bypassing your damaged filter for weeks.

Step 3: Install the New WP37001142 Filter

Remove any protective packaging from your new filter. Hold it by the handle and slide it straight down into the filter cavity. It should drop in smoothly and sit flush with the top edge of the door opening. The frame should fit snugly without gaps on either side — if there's play or wobble, you might have the wrong filter for your specific model.

Step 4: Test the Fit and Operation

Pull the filter out and reinsert it three or four times to confirm smooth operation. The handle should be easy to grip, and the filter should slide without binding. Close the dryer door and run a timed dry cycle for five minutes with no load. Check that air is flowing normally through the exhaust vent outside your home.

Testing After Installation

Run a full drying cycle with a small load of towels. After 30 minutes, pull the lint filter and check that it's catching lint properly across the entire screen surface. If lint is accumulating unevenly or you see lint inside the drum around the door seal, the filter may not be seated correctly. Remove and reinstall, making sure it drops fully into place.

Check your exhaust vent outside after a few loads. You should see a steady flow of warm air but no visible lint coming out. If you're still seeing lint in the exhaust, your vent duct may need cleaning — a clogged filter over time often pushes lint deeper into the vent system.

Frequently Asked Questions

Will this filter fit my Whirlpool model if it's listed for Maytag?

Yes, many Whirlpool and Maytag commercial dryers share the same cabinet design and lint filter assembly. The WP37001142 is a Whirlpool-branded part that's cross-compatible with Maytag models using part numbers 37001142 and 40124401. Verify your model number against the compatibility list — models like MDE5806AZW, MDET336AYW, and MDG308DAWW all use this same filter.

How often should I replace the lint filter versus just cleaning it?

Clean your lint filter after every load, but replace it when you see physical damage — cracks in the plastic frame, tears in the screen mesh, or warping that prevents a tight fit. Most filters last 5-10 years with normal use, but commercial dryers or high-volume households may need replacement every 3-4 years. A bent frame or holes in the mesh let lint bypass the filter entirely.

Why is my new filter harder to remove than the old one?

New lint filters have tighter tolerances and haven't worn in yet. The plastic frame edges are sharper and create more friction against the housing walls. After a few weeks of normal use, the filter will break in and slide more easily. If it's genuinely stuck, check that you have the correct part number — an incompatible filter can be slightly oversized and bind in the cavity.
