Why my Treadmill Belt Slows Down When I Step On It | Solutions

Whenever I step on the treadmill, it gradually slows down. Several factors contribute to a treadmill’s slowness.

Because of its practicality and health advantages, treadmills have become nearly mandatory in our homes.

However, despite precautions and maintenance, treadmills still occasionally break down.

You may run slow on treadmill when you step on it if the drive motor is malfunctioning, the belt is damaged, the tension is inadequate, there is less belt lubrication, or there is some other problem.

Well, there’s nothing to worry about just sit tight and we are going to provide you with resolutions to all your problems.

All of these issues have been handled as follows:

Check Belt If Treadmill slows down When You Step On It

Walking Belt may fray/Break due to regular use. The Belt may have been weakened, making it less effective than usual.

If you suspect a worn belt, you can also measure its power with a DC or AC amp draw.

Typically, treadmills have a modest incline level, and users are advised to walk at a speed of about three mph while on the machine.

Your treadmill needs a new belt if it works great at its highest inclination but begins to slow down when you switch to its lowest level.

You can check the solution if your Weslo treadmill belt is not moving.

Checking Of Belt Tension If Treadmill Slows Down

It’s possible that the walking Belt or the motor belt is excessively tight. you need to adjust it.

Too tight belts may look better, but they put extra strain on the drive system.

You can check the Belt’s tension by lifting the Belt’s middle edge on both sides. Belt tension is fine if you can lift up the edges of the Belt two to three inches.

Greasing/Oiling The Belts If Your Treadmill is Not Working Properly

Your Treadmill slows down when you step in if it has stiffness. Buy the best quality lubricant and pour in it. If you are not sure how to lubricate your treadmill belt properly. We have a one-stop solution for you to probe through this article.

Rollers Out Of Whack If Treadmill Showing Unusual Behaviour

The Belt’s rollers might need to be unbolted and realigned. If there is much or little space between the belt rollers, it causes them to lose their hold on the rollers.

Alternatively, the movable roller at the rear of the walking panel has moved. Reposition the bolts that keep the two rollers in place.

The rear roller can be loosened, relocated, and tightened to the desired position.

Start the treadmill and check. If not, you may need to adjust the bolts further.

Checking Of Motor If Treadmill Slows Down or Stops Working

Potentially, the motor needs new brushes; if you’ve already tried changing the Belt’s settings and it didn’t work. Now check the motor/engine itself.

Stepping on a treadmill with a defective drive motor can slow the treadmill’s movement.

If the Belt has been correctly adjusted and oiled, and the drive motor cannot spin the roller to drive the Belt at the desired speed, then it may be time to replace the drive motor.

Your motor might be overheating and causing it to malfunction and resultantly slowing down the belt. If your motor is making noise you can use this guide to examine it thoroughly.

Verify the motor’s rotational direction. Your pole needs to be moved downwards to apply pressure to the flywheel in the direction the motor is designed to run.

You will replace the motor’s brushes if your pole-like device can slow it down.

You can also perform demagnetization testing. First, remove the bolts keeping the motor’s core in place, and disassemble the motor.

Checking Of Motor If Treadmill Slows Down

When the bolts are removed, the core can be slipped out of the motor housing.

If the case is tough to open because of magnets within, that’s a positive sign that they’re doing their job. However, the motor will replace if the magnets fail to attract the motor core.

Overheating Can Be A Major Cause of Treadmill Slowness

When the treadmill slows down or keeps stopping intermittently when you step in, it may also be due to heavy weight, and you feel an unusual oil odor or burning smell. Overheating just trips the circuit breaker and saves us from severe damage. You can reset circuit breaker easily.

By using the Reset option, the treadmill starts working again. If it trips repeatedly, it might be a serious issue.

The solution is straightforward; you clean the cooling vents, so airflow doesn’t stop.

Keep the motor housing clear of extra clothing and folded mats.

Check the Electronics Creep If Your Treadmill Slows Down When You Step On It

Circuit boards and chips can become loose from sockets due to creep or the expansion and contraction caused by temperature changes.

Creep-related failures may occasionally occur when you step on the treadmill. The problem can resolve by removing the plug and then re-inserting it.

Because the contacts gradually accumulate insulating oxides over time, fuses are also a common source of intermittent power outages. Trained professionals fix these issues.


Problems happen when using a treadmill, as with any technology. Maintaining your treadmill by wiping it down after use and placing it on a mat will help you avoid costly repairs.

When treadmills drop speeds as soon as you walk on them, there are usually a few root causes, and fix them quickly.
