Step-by-Step Guide: How To Fix Burning Smell From Treadmill

Is that burning smell from your treadmill driving you crazy? Fear not! I’m here to provide you with a step-by-step guide on how to fix it and bring back the fresh scent of a well-functioning machine. Let’s get started:

1. Inspection and Cleaning: Get Rid of Debris and Dirt

When it comes to tackling that burning smell from your treadmill, the first step is to inspect and clean it thoroughly. Here’s what you need to do:

  • Check for Any Visible Debris or Foreign Objects:
    Take a close look at your treadmill and remove any debris or foreign objects that may have found their way onto the belt or underneath the machine. These unwanted elements can cause friction and contribute to the burning smell.
  • Remove the Treadmill’s Motor Cover and Clean It:
    Unscrew or unclip the motor cover to access the inner components. Use a soft cloth or a brush to gently wipe away any dust or dirt that has accumulated on the motor cover. This will help ensure proper ventilation and prevent overheating.

    Wipe down the treadmill belt and deck using a clean cloth dampened with a mild cleaner or a mixture of water and gentle detergent. Be sure to remove any dirt, sweat, or residue that may have built up over time. Cleaning the belt and deck will reduce friction and promote smooth operation.

By following these simple cleaning steps, you’ll eliminate any potential debris or dirt that could be causing that unpleasant burning smell.

2. Belt Tension Adjustment: Achieving the Perfect Balance

Now that we’ve cleaned up, it’s time to address the belt tension. Follow these steps to ensure your treadmill belt is properly adjusted:

  • Loosen the Treadmill Belt:
    Locate the tension adjustment bolts or screws on either side of the treadmill deck. Gradually loosen them in small increments, allowing the belt to become slightly more slack. This helps relieve excess tension and reduces the chances of friction-related issues.
  • Align the Belt Properly:
    Once the belt is loosened, make sure it is centered and aligned. Gently move the belt with your hand to position it in the middle of the deck. An off-center belt can cause uneven wear and lead to an unpleasant burning smell.
  • Adjust the Tension:
    With the belt properly aligned, it’s time to adjust the tension. Refer to your treadmill’s manual or manufacturer’s guidelines for specific instructions on how to achieve the ideal tension. Typically, you’ll need to tighten the adjustment bolts or screws evenly on both sides of the treadmill deck until the belt feels firm but not overly tight.

By loosening, aligning, and adjusting the tension of the treadmill belt, you’ll ensure smooth movement and reduce the risk of friction-related problems that can cause a burning smell. 

3. Lubrication: Keeping Things Running Smoothly

To ensure your treadmill operates smoothly and without that burning smell, proper lubrication is key. Here’s how to lubricate your treadmill effectively:

  • Determine the Type of Lubricant Recommended:
    Consult your treadmill’s manual or manufacturer’s guidelines to find out the specific type of lubricant recommended for your machine. Different treadmills may require different lubricants, so it’s essential to use the correct one for optimal performance.
  • Apply the Lubricant to the Treadmill Deck:
    Using the provided applicator or a clean cloth, apply the lubricant to the treadmill deck. Pay attention to the areas where the belt comes into contact with the deck. Apply the lubricant evenly and avoid excessive amounts that could lead to dripping.
  • Reinstall the Belt and Run the Treadmill:
    After lubricating the deck, carefully reinstall the treadmill belt by following the manufacturer’s instructions. Start the treadmill at a low speed and let it run for a few minutes. This helps distribute the lubricant evenly across the deck and ensures smooth operation.

By following these lubrication steps, you’ll reduce friction between the belt and deck, minimizing the chances of a burning smell. 

4. Motor and Electrical System Check: Ensuring Smooth Operation

To address the burning smell from your treadmill, it’s crucial to inspect the motor and electrical system. Here’s what you need to do:
