Whirlpool Dryer Drum Drive Belt Parts — Models & Compatibility

Your Whirlpool dryer's making noise but not tumbling? That's the drum belt calling it quits. This 3394652 replacement belt fits over 50 Whirlpool, Kenmore, KitchenAid, and Roper models — it's the exact OEM-spec belt that wraps around your drum and keeps everything spinning.

Is This the Right Belt for Your Model?

Check your dryer's model number before ordering. You'll find it on a metal tag inside the door rim or on the back panel near the power cord. This belt replaces part numbers AP2946614, 345675, 4319392, 8066064, and PS345337 — if any of those match what's listed in your manual or on your old belt, you're good to go.

About This Replacement Belt

This is a 92-1/4 inch flat belt with 4 ribs on one side. It's the main drive component that connects your motor pulley to the drum — when it wears out or snaps, your dryer will run but the drum won't turn. Most belts fail after 8-12 years of regular use, stretching out or developing cracks along the ribbed side. You'll know it's time when you hear the motor running but see the drum sitting still, or when you hear a rhythmic thumping as a worn belt slips over the pulleys.

Compatible Model Series

This belt works across multiple Whirlpool-manufactured dryer lines. The LTE series (including LTE5243DQB, LTE5243DQ6, LTE6234DQ5, LTE6234DQ3), WET series (WET3300XQ0, WET4024EW0), and LDR series (LDR3822HQ0, LDR3822HQ1, LDR3822PQ0, LDR3822DQ1, LDR3822DQ2, LDR3822DQ3, LDR3422AW0, LDR3422AN0) all use this same belt design. Kenmore 110-series dryers manufactured by Whirlpool also use this part.

What You're Getting

One drum drive belt, part number 3394652. Ships ready to install — no modifications needed. Works with both electric and gas dryer models that use this belt configuration.

Installation Overview

You'll need to remove the dryer's front panel or top/front access to reach the drum. The belt loops around the drum, under the idler pulley, and around the motor pulley in a specific path. It's not complicated, but it takes some maneuvering to get the drum back in position with the new belt properly threaded. Most DIYers can handle it in 45-60 minutes.

Why This Belt Fails

Heat and friction wear down the belt over time. The ribbed side that contacts the drum pulley develops glazing first, then starts to crack. Eventually the belt stretches enough that the automatic tensioner can't keep proper contact, causing slipping. If you've been overloading your dryer or it's been running hot due to a clogged vent, that accelerates belt wear.
