Maytag Dryer Squeaking — Idler Pulley, Drum Bearing, and Belt Squeak Fix Guide

Common Symptoms

• Continuous high-pitched squeal or squeak throughout the cycle
• Squeaking is worst when the dryer first starts (cold) and fades slightly after warm-up
• Rhythmic squeak that occurs once per drum rotation
• Squeaking from the front of the drum area when the dryer is running
• Squeak gets louder over weeks or months until the dryer is unbearably noisy
• Belt-area squeak or chirp that occurs at a specific point in each drum rotation
• Squeal accompanied by a slight burning smell from a dry bearing

Most Likely Causes

1. 1

   Worn Idler Pulley Bearing (WP691366) — Most Common Squeal Source

   The idler pulley WP691366 is a small wheel mounted on a spring-loaded tension arm that keeps the drive belt taut. Its bearing — typically an unsealed sleeve bearing or a small ball bearing — runs dry after years of use, producing the classic dryer squeal: a high-pitched, steady whine that is loudest in the first 30–60 seconds of a cold cycle and sometimes quiets after the metal warms and slightly lubricates. A completely failed idler bearing becomes a grinding noise and eventually seizes, causing the belt to slip off or break entirely. Spin the idler wheel by hand with the dryer unplugged — a bad bearing grinds, wobbles, or drags rather than spinning freely. The idler pulley is typically $15–$25 and accessible from the front panel.

2. 2

   Worn Drum Support Rollers (WP349241T)

   Drum support rollers carry the weight of the drum at the rear bulkhead. As the rubber surface wears, the rollers can develop surface irregularities or the shaft bearing can run dry, producing a rhythmic squeaking sound that corresponds to the drum rotation speed. Unlike the idler pulley squeal (which is steady), a roller squeak has a clear cadence — approximately one squeak per 3–5 seconds as the worn portion of the roller contacts the drum. A roller shaft bearing running dry will also produce a high-pitched squeak. Replace in pairs (there are two rollers on the rear bulkhead) — they wear at similar rates.

3. 3

   Worn Drum Glides / Drum Bearing Pads

   The front drum glides are plastic or composite bearing pads on the front bulkhead that the drum lip slides against. When the plastic wears through, the metal drum edge contacts the bulkhead material, producing a friction squeak — particularly as the drum accelerates at cycle start. The squeak from worn glides is often variable in pitch and correlates to drum speed. It may be louder during the first few minutes of a cycle and quieter at steady speed. Visually inspect the front drum edge through the door opening — if you can see shiny metal-on-metal contact with no visible plastic, the glides are worn out.

4. 4

   Drive Belt Squeaking on Pulley

   A glazed or misaligned drive belt occasionally produces a chirping squeak as it passes over the idler pulley or motor pulley. This sounds like a belt squeal in a car engine — intermittent, rhythmic, and tied to belt travel speed. A glazed belt (shiny surface from heat cycling) loses grip on the pulleys and chirps under load. Misalignment causes the belt edge to rub against the pulley flange and squeak. Inspect the belt surface — glazing appears as a shiny vs. matte finish. A misaligned belt will have visible wear on one edge.

5. 5

   Drum Shaft / Rear Drum Bearing

   Some older Maytag dryer models use a drum shaft bearing at the rear center of the drum rather than support rollers. This bearing is a sealed or lubricated sleeve that wears over time, producing a persistent squeal or chirp from the rear-center of the drum. On models with a shaft bearing (typically older production years), the squeal is steady and rear-centered. Replacement involves removing the drum and replacing the bearing assembly — this is a more involved repair but still DIY-accessible with standard tools.

Quick DIY Checks

1. 1Locate the squeak source by running the dryer briefly and listening carefully: a squeal from the center-rear of the machine (inside the cabinet, not at the drum front) points to the idler pulley or drive belt. A rhythmic squeak from the rear drum area points to support rollers. A friction squeak from the front drum area (near the door opening) points to drum glides. If the squeal fades significantly after 2–3 minutes of warm-up, the idler pulley bearing is the most likely cause (bearing lubrication improves slightly with heat). Record the noise with a phone so you can compare it to the repair guide descriptions.
2. 2Access the dryer interior — remove the front panel: unplug the dryer. On Maytag MED/MGD models, the front lower access panel pops off with a putty knife inserted at the snap clips. Behind it you'll find 2 screws (usually Phillips) at the bottom corners of the front panel. Remove those, then lift the top panel by inserting a putty knife at the front corners (the top panel clips release with moderate pressure). With the top panel open, disconnect the door switch wire harness, then lift the front panel off. The drum, belt, idler pulley, and glides are now accessible.
3. 3Inspect and test the idler pulley WP691366: with the drum still in place, locate the idler pulley on its spring-loaded arm (near the motor, at the base of the drum). Spin the idler wheel by hand — it should spin freely, silently, and without wobble. A bad bearing grinds, drags, or wobbles side-to-side on the shaft. Remove the drive belt from the idler pulley (noting how it was routed — take a photo), then spin the idler wheel again without belt tension. If it still grinds, the bearing is the noise source. Replace the idler pulley — part WP691366 is $15–$25 and the bearing is not serviceable separately.

1. 4Remove the drum and inspect drum support rollers: lift and tilt the drum out through the front opening (have a helper or set the drum on the open door frame temporarily). With the drum out, inspect the two support rollers on the rear bulkhead. Spin each roller by hand — a healthy roller spins freely; a worn roller spins with resistance, wobbles, or grinds. Also look at the rubber surface: worn rollers have grooves, flat spots, or hardened cracking. Sniff the rollers — a burnt rubber smell confirms metal-on-metal contact. Replace both rollers as a pair (WP349241T or model-specific equivalent, $20–$35 for the pair).
2. 5Inspect drum glides while drum is removed: with the drum out, look at the front bulkhead where the drum lip was resting. You'll see 2–4 plastic glide strips or pads at the 10, 2, 4, and 8 o'clock positions around the opening. Run your finger across each glide — if the plastic is worn flush with the metal surface beneath it, the glides are gone. Also look at the drum's front lip edge for wear grooves. Replace the full glide kit for your model ($15–$25 — search model number + 'drum glide kit'). While the drum is out, also replace the front felt seal if it's compressed and non-resilient.
3. 6Inspect the drive belt for glazing and check belt routing: with the drum removed, lay the belt flat and examine both surfaces. A healthy belt is matte black and flexible; a glazed belt has a shiny surface and may feel stiffer. Glazed belts chirp on the pulleys under load. If the belt is glazed or you see edge wear (from pulley misalignment), replace it — WPW10006384 or model-specific equivalent, $15–$20. When reinstalling the belt, confirm it seats in the idler pulley groove and motor pulley groove — a slightly off-track belt will squeak on the pulley flange.
4. 7Reassemble and test: reinstall the drum, route the belt correctly (drum wrap → idler pulley → motor pulley in the factory configuration — reference your photo), reinstall the front panel, reconnect the door switch wire harness, and reinstall the top panel. Plug in the dryer and run a 10-minute timed cycle. The squeak should be gone. If a faint squeak remains in the first minute and then disappears, it's minor belt seating — normal for new belt/pulley. If squeaking persists, re-open and re-inspect the idler pulley seating and belt routing.
