Why Does My Treadmill Keep Stopping? Here's Our Answer!

The problem with most of the treadmills you will find at the local gym is that they are designed to withstand the punishment of countless joggers, but they are not designed to be serviced.

Treadmills are the most popular home exercise equipment, but they’re also the most likely to break down. These machines are more complicated than they seem, and they’re actually constantly adjusting their settings based on your speed, weight, and incline.

If you’re having trouble with your treadmill, you can troubleshoot the problem. However, if you want the treadmill to last you longer, you will need to get it serviced.

If you own a treadmill, you're probably well aware of the fact that these machines can be finicky. And by finicky, we mean it's extraordinarily easy to accidentally stop the belt while you're running, or to accidentally stop the machine from even working in the first place.

For most people, this isn't a huge issue, as they can just hop off the treadmill, and restart it. If you're using a treadmill in a commercial setting, however, this is a major problem.

Reasons why treadmill can stop suddenly

There are few things worse than a treadmill that suddenly stops working mid-run. It's not only dangerous if you're running at full speed, but it can also be inconvenient, since it usually means you'll have to wait until the next time you use the treadmill to find out what's wrong. 

A treadmill can stop suddenly for a number of reasons. To help you avoid experiencing a sudden stop, here is a list of some of the most common reasons a treadmill can stop suddenly.

The motor is overheating

There are many reasons for such a tragedy, but the most common ones are related to the motor overheating. It happens because of lack of lubrication, clogged air vents, or because of the motor being used at a heavy load. 

Treadmill workouts can also be hazardous to your health if the motor is overheating due to a malfunction.

The belt is slipping

There are several reasons why the belt is slipping. This is not always the fault of the treadmill or its parts. Here are the possible causes. Your machine is not level.

If the machine is placed on an uneven floor, you will find the belt slipping and jumping. The problem can be solved by adjusting the legs. If the machine is not even on a flat surface, you should level it.

The safety key has been removed

The safety key has been removed on a treadmill can be a major safety issue. If you do not know how to find the safety key, there is a possibility that you can be injured if the treadmill stops suddenly or even worse.

There are several common reasons why a treadmill could stop suddenly. The most common reason is that the belt has slipped off the motor.

This can happen if the treadmill is not level. The only way to fix this is to find the safety key and reset the treadmill to the correct level.

Treadmill out of balance 

Being out of balance on your treadmill can be a dangerous situation, and we’ve all experienced it. Even if you don't fall or have any close calls, it can cause severe damage to your machine, and in some cases can be a safety hazard.

Most treadmills are equipped with shock absorbers to ease the impact of each push, but if the machine is not properly balanced, the shock absorbers may not be able to compensate for the imbalance.

Treadmills are also susceptible to imbalances in force when they are on an unstable surface, like when they are placed on an uneven surface or a surface that is not level.

Treadmill belt not reaching the motor

When your treadmill stops suddenly, there is a good chance that the belt is not reaching the motor. This can be caused by a variety of issues, so you will want to assess the situation first before you start clearing jams or replacing parts.

The first thing you should do is check your power cord. If it is plugged in, unplug it and check that the end is free of hair, dust and other debris. Next, check the voltage of the socket it is plugged into.

If the voltage is not correct, then you will need to have an electrician come out. Some treadmills require a higher voltage than others.

 Treadmill belt too loose

Treadmill belts are designed to slip when they reach a certain point in their rotation. This is because there needs to be a space between the belt and the flywheel for the motor to start it spinning.

If the belt is loose, the deck may not move as it should, or it may stop moving altogether. Loose belts can cause damage to your treadmill and they can cause injuries to the user. It is important to know how to tell if your belt is too loose and how to fix it if it is too loose.

Treadmill belts are the rubber belts that go around the running and walking decks of a treadmill. These belts are used to keep the deck moving in a consistent motion while the user is on the treadmill.

Treadmill power cord loose

Treadmill power cord loose is one of reasons why treadmill can stop suddenly. This is the most important part of the treadmill, if the power cord is broken, the treadmill can not run.

This can be caused by a number of problems, from the cord itself being damaged, to the plug socket not being properly inserted, or even to the power cord being too long and tightly wound. Another common cause of a treadmill not powering up is to do with the key or the circuit board.

How do I restart my treadmill?

It's a common problem: you're running a few miles on the treadmill and suddenly it starts to smell like burning rubber.

Or maybe you've been running on an incline and are having trouble getting back to level ground. Or it's a brand-new treadmill, and for some reason it's stopped moving.

The good news is that restarting a treadmill is usually pretty easy. The bad news is that it's pretty important to turn off the power before you try to do anything else.

The treadmills in your gym generally have two buttons on them - one to power it up and start walking, and one to power it down. In order to restart it, you'll need to power it down, and then go through the same process to power it back up.

The exact process will vary by manufacturer, so consult your treadmill's manual for step-by-step instructions.
