Title: Dryer Makes Screeching Sound: Troubleshooting and Solutions

When the soothing hum of your dryer is interrupted by a screeching sound, it can be not only annoying but also concerning. A dryer that makes a screeching noise could be signaling a problem that needs attention. This article will guide you through the common causes of a screeching dryer and provide practical solutions to help you restore peace and quiet to your laundry routine.

**Identifying the Cause**

1. **Tight or Damaged Belt:**
The most common cause of a screeching sound in a dryer is a worn or damaged drive belt. This belt turns the drum and can become loose, tight, or frayed over time, leading to the characteristic high-pitched noise.

2. **Drum Support Rollers:**
The rollers that support the drum can also cause screeching if they are worn out or damaged. When these parts fail, they can rub against the drum, creating a screeching sound.

3. **Worn Motor Brushes:**
The motor that powers the dryer may have brushes that are worn down. These brushes help the motor function smoothly, and when they're worn, they can cause the motor to screech.

4. **Foreign Objects:**
Sometimes, a simple piece of lint or a forgotten item like a sock or a small toy can get caught in the drum, causing a screeching noise as it rubs against the metal.

5. **Drum Bearing Issues:**
If the drum bearing is damaged or has dried out, it can cause a loud screeching noise, especially when the drum is spinning.

**Troubleshooting Steps**

1. **Check the Belt:**
- Turn off and unplug the dryer.
- Open the dryer door and locate the drive belt.
- Inspect the belt for signs of wear, such as fraying or glazing.
- If the belt is loose, it may need to be adjusted or replaced.

2. **Inspect Drum Support Rollers:**
- Remove the drum to access the rollers.
- Look for any signs of damage or excessive wear.
- Replace any rollers that appear to be the source of the noise.

3. **Examine Motor Brushes:**
- With the dryer unplugged, inspect the motor for worn brushes.
- If the brushes are worn, they will need to be replaced.

4. **Search for Foreign Objects:**
- Carefully check the drum for any foreign objects that may be causing the noise.
- Remove any lint or debris that could be caught in the drum.

5. **Assess Drum Bearing:**
- If the drum bearing is the issue, you may need to replace it.
- This can be a complex task and may require professional assistance.

**Preventive Measures**

- **Regular Maintenance:** Clean the lint filter after every use and perform a deep cleaning of the dryer's vent system regularly to prevent lint buildup.
- **Check for Obstructions:** Always ensure there are no foreign objects in the dryer before starting a cycle.
- **Lubrication:** Some dryers require periodic lubrication of moving parts. Consult your dryer's manual for specific maintenance instructions.

**When to Call a Professional**

If you're not comfortable performing these checks and repairs yourself, or if the screeching continues after you've tried these solutions, it's time to call a professional. A qualified technician can diagnose and fix the problem, ensuring your dryer operates safely and quietly.

In conclusion, a screeching dryer is often a sign of a mechanical issue that requires attention. By following these troubleshooting steps and taking preventative measures, you can keep your dryer running smoothly and quietly. Remember, if you're unsure about any of the steps or if the problem persists, it's best to consult with a professional to avoid further damage or potential safety hazards.
