Possible Causes of Humming Noise in Samsung Dryer

The most common reason why a Samsung dryer would make a humming noise is due to a faulty motor or a blocked blower wheel. Here are some other possible reasons:

  • Clogged lint screen: If the lint screen is clogged, it can cause the dryer to overheat, leading to a humming sound.
  • Worn-out drum roller: A worn-out drum roller can also cause the drum to make a humming noise as it rotates.
  • Belt damage: The drive belt that rotates the drum might have been damaged or broken.
  • Faulty idler pulley: The idler pulley keeps tension on the drum belt, and if it’s faulty, it can cause your Samsung dryer to produce noise.

How to Fix Humming Noise in Samsung Dryer

Once you’ve identified what’s causing your Samsung dryer to hum, you can take necessary steps to fix it. Here are some DIY solutions you can try:

  1. Clean the lint filter: Detach the lint filter from its position; clean any debris by wiping with soap and water or brushing with an old toothbrush.
  2. Check for blockages: Check if there are any blockages in your dryer such as a clogged vent or blocked blower wheel. Use a vacuum cleaner to remove any debris or dirt inside the dryer.
  3. Replace faulty parts: If you find any worn-out drum rollers, damaged belt, or faulty idler pulley, replace them with new ones. You can purchase genuine Samsung dryer parts from authorized dealers or online stores.

When to Call a Professional for Repairing Your Samsung Dryer

If the above DIY solutions do not work, it’s best to call a professional technician who has experience in repairing Samsung dryers. Here are some instances when you should seek professional help:

  • If you’re unsure about how to fix the problem

In conclusion, if your Samsung dryer makes a humming sound and doesn’t start, it’s crucial to identify what’s causing the issue before taking necessary measures. Cleaning the lint filter and checking for blockages are easy DIY solutions that can resolve the problem. However, if they don’t work, seek professional help from an experienced technician who can diagnose and repair your Samsung dryer efficiently.

How to troubleshoot a Samsung dryer that won’t start?

Check the Power Supply

The first thing to check when your Samsung dryer won’t start is the power supply. Ensure that the dryer is plugged in and that there’s power in the outlet or circuit breaker. If you find no issues with the power supply, move on to checking other possible causes.

Inspect the Door Switch

If your Samsung dryer’s door switch is faulty, it may not start. Inspect it by opening and closing the door while listening for a clicking sound. The clicking sound indicates that the switch is functional. If it doesn’t click, then it needs replacement.

Examine Thermal Fuse

A defective thermal fuse can also cause your Samsung dryer not to start. The thermal fuse protects your dryer from overheating by cutting off power if it gets too hot. Check to see if the thermal fuse is blown by using a multimeter, and replace if necessary.

Common issue with Samsung dryers making humming noises and not starting

Clogged Lint Filter

One common cause of humming noises in Samsung dryers is a clogged lint filter. A dirty filter restricts airflow, causing heat build-up within the dryer resulting in humming sounds or even preventing it from starting at all. Clean or replace the lint filter regularly to prevent this issue.

Belt Problems

Another potential reason for humming noises and failure to start could be related to belt problems within your Samsung dryer. Over time, belts may become loose or break entirely, causing tension issues that lead to strange noises or no movement at all. Check and replace belts as required.

DIY solutions for fixing a Samsung dryer that won’t start and is making a humming noise

Clean the Dryer’s Vent

Cleaning the dryer’s vent is one of the most effective DIY solutions for fixing a Samsung dryer that won’t start and is making a humming noise. A clogged vent restricts airflow, causing overheating and humming sounds. Unplug your dryer, detach the vent hose, and clean it out thoroughly.

Replace Faulty Parts

Replace any faulty parts identified during troubleshooting. If your Samsung dryer has a broken thermal fuse, door switch, or belt issues, replace them with new ones to ensure smooth operation. Consult the user manual or seek assistance from an expert if uncertain about how to proceed.
