Sticking Belt Symptoms When Running
You will find various types of treadmills on the market today. Whether it’s a treadmill for heavy persons or regular users, each one will show symptoms while sticking. You can hardly move the belt on the deck to the front or backward. While running, you can feel the belt causing an irregular stoppage. Unless you are lucky, you might fall on the deck if it sticks at once. However, an unplugged treadmill having rest for many days may stick with the deck.
Possible Causes Behind Sticking Belt
A treadmill belt connected with every possible part may cause trouble. Considering all the possibilities we have gathered the most probable cause.
- Lack of lubrication
Maybe it’s been a long time since you lubricated the treadmill belt. Lubrication is one of the most important maintenance theories you must follow regularly. Improper lube will cause excessive friction between the deck and the belt and further result in sticking the belt.
- The belt is off-centered
An off-centered belt is dangerous for a user while running or even the treadmill is plugged in. It will further end up causing your treadmill to stick. It will get stuck on the part of the rotation.
- The belt is too tight or too loose
A too-tight belt causes incorrect tension between the deck and the belt itself. The same applies to a belt that is too loose. Belt not adjusted properly is one of the main reasons cause a treadmill belt sticking.
- The drive motor belt is loose
There might be an unusual scenario to this portion of the story. When you are searching for the culprit in the “belt context”, a drive motor belt can sometimes play the role behind the scene. Sometimes the drive belt gets loose and causes the belt to slip. A black shaving may come out from the motor.
- The front roller has been separated from the shaft
This is the most unusual among all. The shaft pulls the front roller tight while running. The treadmill belt will stick if the front roller separates from the shaft. Considering the symptoms you may need to replace the roller.
How to repair a treadmill belt that is sticking
You must be able to diagnose all the possibilities first. Unplug the treadmill and try to check out all the possible causes that might happen to your treadmills. Check out if the belt is off-centered or the belt needs lubrication. Once you have found the exact cause, proceed with our ” step-by-step solutions”
Things You Need:
- Dry cloth
- Silicon lube
- Drive motor belt
Step 1: Inspect the Belt
After unplugging the treadmill inspect the belt properly whether it is wrecked or somehow damaged. If the belt is cracked or torn, you must replace the belt.
Step 2: Lubricate the belt
Before lubricating loose up the belt with the help of the screwdriver by turning the front and back portion counterclockwise. Now lift the belt and put the lube on the deck according to the instructions of the manufacturer. Most of the treadmill is comfortable with the silicone lube. You can use it unless something mandatory is mentioned for your model. There is a video illustrating the lubrication procedure that might help you.
Step 3: Fixing the off-centered belt
If the lubrication is successful, and still your treadmill belt is sticking, it’s time to check the next step. Centering the treadmill belt is not that hard to fix. Every treadmill available on the market has two bolts at the rear of the machine. One is on the left side, another one is on the right side. You can use only the LEFT side bolt. Never touch the right side bolt to make the belt centered.
Step 4: Adjust the tension
After you have fixed the off-centered belt it’s time to check the tension of the belt whether it’s too tight or too loose. To examine the tension, try to lift the belt from the deck board. The belt must be 3 inches apart from the deck. It’s time to adjust the tension.
With the help of a wrench adjust the screws locating the adjustment. Increase the tension by turning the screws clockwise if it is loose. And decrease the tension to the proper measurement by turning the screws counterclockwise.

Step 5: Replace the drive motor belt
If you are following “step-5” and didn’t find your solutions till “step-4”, your treadmill is probably facing an unusual belt sticking problem. However, you need not worry a bit! Go and test the drive belt. First, unscrew the motor cover with the help of a wrench. Take a look at the belt. It’s a small belt at the side of the motor. Check if any black shavings are coming from it. Black shaving means the belt is faulty and you need to replace it with a new motor belt.
The motor belt might also get loose within time. In that case, you also need to replace the drive motor belt.
Step 6: Fix the front roller pulley
In case the front roller pulley has been separated from the shaft you might need to change the roller as the last option. But before that, try to examine the front roller. First, place a mark starting on the front roller pulley and ending on the metal shaft with the help of paint or marker. Now get on the deck and try to work on it. Notice if the mark is separated while you are trying to walk.
If so, then the roller is in bad condition, and the screws put through the roller to the metal shaft are faulty. You might need to change the screws, or sometimes the whole roller. This is the most unusual cause behind sticking your treadmill belt. However, the sticking problem should come to an end at this step. If the belt sticks again, there must be some other causes not related to the belt. It’s the high time you contact an expert.
Unless you maintain your treadmill regularly, it might give you a rough day sometimes. Sticking the belt is one of the most common ones, yet it may turn its back unless you can handle it properly. To avoid possible damages, keep an eye on the belt if the tension, lubrication are going on. You don’t need to be an expert to fix the basic stuff.
