Why My Treadmill Stopped Working [Three Frequent Cases And How To Fix]

A treadmill is your sidekick on the journey to keep fit. However, it may become a headache if it breaks down one day. You may wonder: “Why my treadmill stopped working and how to fix it?” 

Many reasons are leading to the malfunction of your machine. You can blame the power source, bolts, running belt, or the motor. With each cause, you have a specific solution to fix your treadmill. 

This article will discuss the reasons why your treadmill stops working. We also suggest some practical solutions to tackle the problem. Let’s read on to discover!

Reasons For Why My Treadmill Stopped Working

Treadmill malfunctions may happen in different ways. We divide the problems into three primary keys as follows. You can also consult the solutions suggested for each issue.

Why will my treadmill not turn on?

If the treadmill doesn’t start, you’ll need to figure out what’s happening. 

Depending on the brand, age, model, and condition of your equipment, you may be able to resolve the issue yourself.

  • How to solve:

Start with the basic options, such as the power supply. Then, work your way up to the more complicated features, such as the controller.

Power supply

The simplest and most common fault is that you haven’t plugged the machine. Ensure to hook it into an energized outlet. Also, check that the prongs on the power socket really aren’t twisted or distorted.


It’s essential to observe the connections between the machine and the power adaptor. 

Some treadmill types need adjusting the power source before it reaches the motor. 


Your machine will not run if the fuses have broken. Fortunately, a blown fuse is often a straightforward fix. You can employ a multimeter to examine the fuses or bring them to an appliance store for inspection.

If any of your fuses have broken, make sure you change them to fuses of the same amperage capacity.


Maybe the display isn’t working if your equipment won’t switch on. Ensure that all cords connecting the machine to the monitor are secure.

Check to see if the screen is receiving electricity. You may test with a multimeter at the connecting points between the power source and the screen.

Why does my treadmill stop when I step on it?

The belt can be overstretched during exercise, causing the rollers to lose grip.

You can also blame the imbalance or lose bolts that make the machine lose its original form. 

  • How to solve:

Fixing this issue is relatively easy. It would help if you prepared a hex spanner that comes with the treadmill. This tool helps you fix the bolts by loosening and tightening the roller. 

The detailed instructions are as follows:

  • Unplug the machine from the power source.
  • Find the bolts on the back of the machine.
  • Twist the bolts in a clockwise direction. Don’t tighten them, or it may cause premature belt stretching.
  • Finally, test the treadmill to see if you have addressed the issue. 
  • Repeat the procedure if your machine still can’t work.

Why does my treadmill stop suddenly?

It may not be pleasant to cope with a treadmill that abruptly stops right in the middle of your workout. 

The unexpected halt might result from a lack of belt upkeep or a poorly oiled base. 

Treadmills can sometimes come to a sudden halt due to engine malfunctions or a defective circuit.

  • How to solve:

Some reasons are leading to the sudden stop while running. Hence, you have to consider the situation and come up with an appropriate approach.

Running belt

If the belt does not appear flat or has worn out, you should either change or oil it. The solution depends on how bad it is. 

If you intend to lubricate the belt, use the silicone-based lubricant to reduce tension between the belt and the deck.


If the problem is with the engine, you will pay a lot of money to repair it. You may need to change it if it has ceased functioning or is performing poorly. 

People who are using their machines for high-intensity workouts frequently experience motor problems due to faulty circuits. These are the most dangerous. They may cause serious safety problems if not correctly handled.


Another problem you may encounter is the platform’s lack of slickness. To reduce overheating caused by friction, you need to lubricate the platform.

How To Maintain The Treadmill?

Prevention is better than cure. Don’t wait until problems arise and look for solutions. You need to care for your machine carefully. It can last longer while still running correctly.

Clean the motor

At least once every three months, clean the engine section.

It’s a great idea to remove the motor’s hood and vacuum to clear any dust or dirt. This step will assist in maintaining the highest productivity of the engine.

The user handbook offers explicit instructions for doing so. Whenever in doubt, you can follow those directions.

Lubricate the running belt

Some treadmills require belt lubricating, while others offer “self-lubricating running belts” that don’t. To find out if you need to oil your belt, check the user guide.

If your treadmill isn’t costly, you need to lubricate it every two or three months. The frequency depends on how often you use it.

Most belts need 100% silicone lubrication. It’s essential to apply the right kind of lubricant to not end up screwing your belt.

Tighten the belt

Although most decent treadmills arrive with the belt pressure set, the belt still may loosen with time.

The stress on the deck may progressively lessen when the running belt stretches. You’ll notice this because the belt will seem like it’s sliding about too much towards the deck. 

You can adjust the belt tension by tightening the bolts at the end of the deck. For further information, consult the user manual.

Utilize a surge processor

It would be best to plug the machine into a surge processor to safeguard the electronics from any sudden power spikes.

When your equipment is not in use, you can unplug. It may save you a few dollars on your electric bill, but it’s not essential if you use a robust surge protector.

Wipe down the equipment after each use

You want your machine to have a nice appearance and function as long as possible. So, after each usage, begin wiping out every section of the equipment that has sweat on it.

Cleaning the console weekly is also a great thing. Don’t bother with costly detergents. A damp cloth can suffice.
