Cardio equipment, such as treadmills, elliptical machines, and stationary bikes, is crucial in maintaining an effective workout routine. However, consistent use of these machines in a gym setting can lead to wear and tear, making them prone to issues that may hinder their performance. In this guide, we’ll discuss some tips for troubleshooting and repairing common cardio equipment issues.
Inspect the Equipment
If a piece of fitness equipment isn’t working correctly, begin troubleshooting the issue by carefully examining all visible components, including belts, handles, pedals, and frames, for signs of damage. Specifically, look for cracks, frayed belts, or loose bolts, as these can cause malfunctions during use or pose safety risks.
As you examine the equipment, pay particular attention to moving parts such as the running belt on a treadmill or the internal belt drive of a stationary bike. These areas often experience significant wear due to frequent use. If you notice uneven movements or a wobbling sensation, it may indicate loose or misaligned components.
Lubricating Moving Parts
If the belt or pedals on a piece of cardio equipment seem to stick or make unusual noises, it may be due to a lack of lubrication. Over time, the belt or pedals can become dry and cause friction, leading to premature wear.
Guidelines for lubricating specific equipment include:
- Treadmills: Concentrate on the area underneath the running belt
- Elliptical machines: Lubricate the roller wheels and rail guides
- Stationary bikes: Focus on the chain or flywheel as the manual directs
When selecting lubricants, only use those approved by the manufacturer to avoid damage. Clean the parts before lubrication to remove dust or debris that could mix with the lubricant and cause a buildup.

Read the Machine’s Manual
If your cardio equipment isn’t working like it usually would, read through the owner’s manual that the machine came with. Sometimes, the solution to a problem can be as simple as a quick adjustment or reset. The manual will also provide valuable information on maintenance and troubleshooting specific to your machine.
Moreover, some manuals include detailed diagrams of the equipment and its components, making it easier to identify potential issues and locate the necessary parts for repair. It may also have step-by-step instructions on how to address common errors. For example, a treadmill manual may have instructions on recalibrating the incline or speed sensors.
Call a Repair Professional
Persistent problems like unusual noises, heavy vibrations, or complete failure to operate often indicate underlying mechanical or electrical faults beyond the scope of essential repairs. It’s best to call a repair technician rather than trying to fix the machine yourself. Any attempt to open the machine’s casing or tamper with electrical connections can cause further damage, void your warranty, and pose safety hazards.
Before contacting a repair professional, gather as much information about the issue as possible to help the technician identify its source quickly. Start by documenting any error codes displayed on the console and providing detailed descriptions of symptoms like noises or movements; provide this information to the repair professional.
Specific Issues with Equipment
While there are broad steps to troubleshooting and repairing common cardio equipment issues, each machine has some specifics. Below, we’ve provided a few examples of common issues and how to resolve them.
Treadmills
The treadmill is a staple of any cardio workout routine, but it’s also one of the most widely misused machines. Two common issues with treadmills are belt breaking and motor failure.
Belt Issues
A treadmill usually has at least two belts: the running belt that moves and a motor belt that connects to the deck. Belt breaking often occurs due to wear from constant use, insufficient lubrication, or debris buildup. Check the running belt for frayed edges, cracks, or tears in either belt during regular inspection.
Generally, you don’t know if there’s a problem with your motor belt until it breaks; you’ll still hear the motor’s hum, but the running belt won’t move. To fix this, you’ll have to replace the motor belt.
Motor Failure
Motor failure commonly results from overheating or excessive strain caused by misuse or overloading beyond weight capacity. When a treadmill motor starts breaking down, it may sound strange or move the running belt at improper speeds. Alternatively, a damaged motor could quit working altogether; if this happens, the running belt will not move.

Ellipticals
Ellipticals are a popular alternative to treadmills for low-impact workouts. Common issues with ellipticals include resistance and noise problems.
Resistance Issues
If the resistance feels too easy or hard when using an elliptical, it may indicate a problem in the magnet or motor that controls resistance. Check for loose wires and clean any debris around these areas. If the issue persists, consult a technician to replace or realign parts as needed.
Noise Problems
Ellipticals can make noise when pedals wobble, are incorrectly aligned, or something gets stuck inside the machine. Inspect all components and remove any visible obstructions before using them again. If the problem persists, contact a repair technician to handle more complicated issues involving internal components like bearings or belts.
Stationary Bikes
Stationary bikes are convenient for low-impact cardiovascular exercise. Common problems with stationary bikes include tension issues and pedal malfunctions.
Tension Issues
Tension problems occur when the pedals feel too loose or tight, making pedaling difficult. This issue often results from a damaged belt or worn brake pad on magnetic resistance bikes. Inspect the tension components for wear and replace them as needed.
Pedal Malfunctions
The pedals of your stationary bike may jam or stop working correctly due to stripped threads or broken straps. Regularly inspect the pedals and replace them if necessary, ensuring that they are securely attached to the bike before use.
All Equipment Issue
Pretty much all modern cardio equipment has a display console that shows information such as current speed, heart rate, and distance. These consoles can become unresponsive or display incorrect information due to various reasons, such as low battery, loose connections, or software glitches.
Troubleshooting can be done by checking power sources, unplugging and re-plugging cables, or performing a factory reset if available. Depending on the complexity of your display counsel, you may also have to update the software. If your attempts at troubleshooting don’t resolve the issue, it’s best to contact a professional for assistance.
