How to Fix Common Treadmill Problems
We all know treadmills are a great addition to a home gym. They provide an effective and relatively safe cardiovascular workout. Like most workout machines, a treadmill may occasionally malfunction, especially if you use it frequently. Treadmills come in a wide range of sizes, shapes, and features – but there are several key problems that pop up on most types of treadmill machines. Timeliness is key. You can minimize damage and downtime when you act quickly. Learn how to fix a treadmill with these effective tips for common treadmill repair.

Erratic Speed
There may be a problem with your machine if the speed varies as you’re running. Begin by checking the owner’s manual for the recommended speed setting. Set the machine to the recommended setting, but do not get on. Observe the treadmill for several minutes to see if there’s hitching in the belt. This is often a sign that you need a new belt. If you’re new to this, read my review here on “How to Change a Treadmill Belt.” If the machine shuts down, there may be a problem with the motor, or the machine may have a faulty circuit. For everything you ever wanted to know about treadmill motors, you can read up on that topic here.

Slipping Belt
If you feel a slipping sensation when using your treadmill, it may be in need of minor treadmill repair. To fix treadmill problems associated with slippage, align and tighten the running belt. Belts can slip when there’s too much friction or if the belt is over-tightened. To check if the belt is too tight, lift it in the center. There should be a gap of approximately two to three inches. If not, the belt is likely too tight.
No Display
When problems occur with the console display, the solution is usually relatively simple. To fix treadmill console displays, check the length of the power cord and visible wires. Worn batteries or crimped cords will need to be replaced. Treadmill repairs associated with a magnetic pickup on the flywheel will include a thorough examination. The magnet may have fallen off and will need to be replaced. If the console develops static, the circuit breaker may need to be reset. Unplug the power cord for 60 seconds to fix this problem.

Burning Smell
If you notice a burning smell from the treadmill, it could indicate something serious. Immediately turn off the treadmill and unplug the power cord from the wall. Common causes of a burning smell from a treadmill include friction between the deck and back or a short in the wiring, electronics, or motor. These problems could potentially cause a fire, making immediate treadmill repair essential. One of the biggest issues I see in consumer complaints about treadmills is their own failure to maintain them. Proper lubrication of your belt and deck, and the occasional vacuuming of your motor case will go a long way to preventing these problems.
Non-Working Motor
Fixing a non-working treadmill motor can be one of the more costly treadmill repairs an owner will run into. The motor may need to be replaced if powered at full speed, cannot be adjusted, and continues not to work or works poorly. Treadmills that power on at a full speed often experience problems with failed circuits, leading to safety issues. Professional attention may be required to repair or replace the circuit or motor.

Heated Belt
Too much friction on the running belt can cause it to heat up and not run properly. Treadmills require lubrication to limit the amount of friction between the platform and belt. When the friction increases to a certain point, the machine is automatically set to power off. This may be the cause for the machine to stop working suddenly. Try lubricating the belt. Ultimately, it may need to be replaced.
It’s common to run into some hangups when learning how to fix a treadmill. While the issues mentioned above are pretty common, the solution isn’t always easy. Treadmill parts may need to be completely replaced before the machine can be used again. It’s important to learn how to fix a treadmill the correct way to avoid injury to yourself and damage to the machine. Troubleshooting the treadmill can help determine the point of failure within the machine. This will also give you the opportunity to fix or replace the part yourself or with the help of a skilled repair technician.
Inspecting rollers from time to time is a good idea.
Proactive Maintenance
Preventative maintenance on your treadmill is essential to ensure its longevity and optimal performance. Firstly, regular cleaning is crucial; this includes wiping down the machine after each use to remove sweat and debris, and vacuuming around the belt and deck area to prevent accumulation of dust and fibers. The belt requires periodic lubrication to reduce friction and wear, following the manufacturer’s guidelines on the type and frequency of lubricant to be used. Additionally, it’s important to check and tighten any loose bolts or screws regularly, as these can become loose with vibration and movement during use. Ensuring the belt is properly aligned and tensioned is also vital for smooth operation and to prevent uneven wear. Lastly, keeping the treadmill in an environment with stable temperature and humidity levels can prevent electrical and mechanical parts from deteriorating prematurely.
How long will your Treadmill Last
The average lifespan of a treadmill typically ranges between 7 to 12 years. However, this can vary significantly based on several factors. Key among them are the quality and durability of the treadmill itself, the frequency and intensity of its use, and the consistency and thoroughness of maintenance and care. Higher-end models often last longer due to better construction and components, while budget-friendly models may have a shorter lifespan. Regular maintenance, such as cleaning, lubricating, and checking for wear and tear, can significantly extend a treadmill’s life. Additionally, how the treadmill is used — whether it’s for light walking or intense running — can also impact its longevity. Proper usage, in accordance with the manufacturer’s guidelines, plays a crucial role in maintaining its condition over time.
