4392067RC 4392067 Dryer Maintenance & Repair Kit

Key Features

• Complete Drive System Overhaul: A comprehensive 6-piece kit designed to restore the mechanical rotation of the drum, including four high-performance rollers, a reinforced drive belt, and a precision-tensioned idler pulley.
• Quiet-Run Drum Rollers: The W10314173 rollers feature a specialized rubber outer layer and high-grade internal bushings, engineered to eliminate the "thumping" and "squealing" sounds caused by flattened or seized factory rollers.
• High-Traction Ribbed Belt: The 661570V drive belt (approx. 93.5 inches) is manufactured from reinforced EPDM rubber with a 5-rib profile, providing maximum grip and resistance to stretching under heavy, wet laundry loads.
• Upgraded Idler Pulley Assembly: Includes an improved ball-bearing idler pulley that maintains constant tension on the belt, preventing slipping and reducing the mechanical vibration that leads to motor burnout.
• Snap-Lock Retention Hardware: Features a full set of replacement tri-rings and retaining clips, ensuring all rotating components are securely locked onto their shafts for safe, long-term operation.

Compatibility & Fitment

This master repair kit is specifically designed for Whirlpool-built 27-inch front-load and high-efficiency dryers. Key compatible series include:

• Whirlpool Cabrio & Duet: Fits hundreds of models including WED9200, WED9500, WED9250, and WED7500 series.
• Maytag Bravos XL & Epic: Compatible with MEDB850, MEDB950, MED9700, and MGD series high-capacity dryers.
• Kenmore Elite (110 Series): Fits the vast majority of HE (High Efficiency) 110-prefix models produced by Whirlpool for Sears.
• Amana & KitchenAid: Direct fit for many NED and KEDS series high-efficiency units.
• Note: This kit is intended for the "Thin" or "Standard" roller shafts found on Duet and Cabrio platforms. Verify your model number if your unit is an extra-wide steam model.

When to Replace

• Squealing or Chirping: A high-pitched noise usually indicates the idler pulley bearing is failing or the roller bushings have run dry.
• Persistent Thumping: A rhythmic thumping sound (even when the dryer is empty) suggests the rubber on the rollers has developed flat spots or has begun to peel.
• Drum Will Not Spin: The motor runs but the drum stays still, indicating the belt has snapped or the idler pulley arm has collapsed.
• Loud Grinding Noise: Significant metal-on-metal grinding sounds suggest the rollers have worn down completely, allowing the drum to rub against the internal bulkhead.
• Dryer Vibrates Heavily: If the rollers are out of round, the entire cabinet will vibrate, which can lead to early failure of the heating element or control board.

Installation Tips

• Safety First: You MUST unplug the dryer. This repair requires a complete disassembly of the front cabinet and removal of the drum.
• Accessing the Drive: You will need to remove the top panel, the control console, and the front bulkhead. Be careful with the door switch wiring during removal.
• The "Belt Grooves" Rule: When installing the new 661570V belt, ensure the ribbed side is facing down against the drum. The smooth side should be in contact with the idler pulley.
• Vacuum the Cabinet: **CRITICAL:** While the drum is removed, use a vacuum to clean the entire base of the dryer. Removing accumulated lint prevents motor overheating and significantly reduces fire hazards.
• Inspect the Shafts: Before sliding the new rollers on, wipe the metal shafts clean. Do not use oil or grease on the rollers; they are designed to run dry. If the shafts are scored or bent, they must be replaced separately.
