## Problem

Push the start button, motor hums, drum doesn't spin. Reach in and spin the drum by hand — it moves freely. **Belt is broken or off the drum.**

## Which Part?

- **OEM:** 341241 (Whirlpool part number)
- **Compatibility:** All Whirlpool 29" dryers from 1965+ — including Kenmore, Maytag, Amana, Roper, Estate. This is one of the most universal parts in appliance repair.
- **Original:** $15-25
- **Aftermarket:** $8-15 (same spec, often same factory)

## Tools

- 1/4" nut driver or screwdriver
- Putty knife (to release the top panel clips)
- Flashlight

## Steps

**1. Unplug the dryer.** Seriously, unplug it.

**2. Pop the top panel.** Slide a putty knife under the front edge, about 2-3 inches from each corner. Push in to release the spring clips. The whole top panel flips up and back.

**3. Remove the front panel.** Two screws at the top corners (now exposed) + two inside the door frame on some models. The front panel comes forward and off — watch for the door switch wires, unplug them.

**4. Lift the drum out.** The belt is probably sitting on the floor of the dryer now, or wrapped around the motor shaft.

**5. Thread the new belt.**
   - Grooved side **facing the drum**
   - Wrap around the drum first (you can see a worn ring where the old belt rode)
   - Route down and around the **idler pulley**, then around the **motor pulley** in a figure-8

**6. Hold the belt in place on the motor pulley** while lifting the drum back in. This is the tricky step — work slowly.

**7. Spin the drum by hand** to check belt tension. It should feel springy, not loose.

**8. Reverse the teardown.** Front panel, top panel.

**9. Plug in, test.**

## Pro Tip: Buy the Kit

If your belt broke after 10+ years, the **idler pulley and drum rollers are probably worn too.** They sound the same (humming, squeaking, failure-to-spin). Buy the **"29-inch dryer repair kit"** (4392065 / 4392067) — belt + pulley + rollers — for ~$20. You'll save a second teardown.

> **我们卖这个 kit 吗？** Yes — the full 4392065 compatible kit with upgraded sealed-bearing rollers.

## 中文版

## 问题现象

按启动键，电机嗡嗡响，内筒不转。手动转内筒——可以自由转动。**皮带断了或者脱出了。**

## 找对件号

- **OEM**：341241（惠而浦件号）
- **兼容性**：1965 年以后所有惠而浦 29 寸烘干机——包括 Kenmore、Maytag、Amana、Roper、Estate。这是家电维修里兼容性最强的件之一
- **原厂**：$15-25
- **第三方**：$8-15（同规格，经常是同一家工厂）

## 工具

- 1/4 寸螺丝刀头或螺丝刀
- 腻子铲（撬开顶盖卡扣）
- 手电

## 步骤

**1. 先拔电源。** 真的，拔。

**2. 弹开顶盖。** 腻子铲塞到前边沿下，离两角各 2-3 寸处往里推，弹开弹簧卡扣。整个顶盖往后掀开。

**3. 拆前面板。** 顶部两角两颗螺丝（现在能看到了）+ 有的型号门框内侧还有两颗。前面板往前取下——注意门开关的线，拔掉。

**4. 把内筒搬出来。** 皮带这时候应该掉在底部，或者缠在电机轴上。

**5. 装新皮带：**
   - 带槽的那面**朝向内筒**
   - 先绕内筒（你能看到之前皮带磨出的那圈痕迹）
   - 下来绕过**惰轮（idler pulley）**，然后 8 字形绕到**电机轮**上

**6. 装回内筒时用手摁住电机轮上的皮带。** 这步最烦，慢慢来。

**7. 手转内筒检查张力。** 应该有弹性，不是松垮垮的。

**8. 倒序装回。** 前面板，顶盖。

**9. 通电，测试。**

## 小贴士：买套装

如果皮带是 10 年以上才断的，**惰轮和内筒滚轮也差不多该换了**。症状一样（嗡嗡声、嘎吱声、不转）。直接买**29 寸烘干机维修套装（4392065 / 4392067）**——皮带 + 惰轮 + 滚轮——$20 左右。省你再拆一次机器。

> **我们卖这个 kit 吗？** 卖——4392065 兼容套装，配升级的密封轴承滚轮。
