The Treadmill Turns On But won’t Run

Suppose you turn on your treadmill’s switch someday, make the necessary settings in an attempt to start your exercise for the day, and nothing happens.

In that case, you will need to troubleshoot the possible issue by inspecting various parts and components of your machine.

Why this may occur (the causes)?

Treadmill problems

The following are possible reasons why your treadmill may fail to start even though the console display comes on.

1. The safety key is not inserted correctly

If the safety key is not rightly inserted, the treadmill may fail to run.

Solution: Check the console to confirm if the safety key is rightly inserted.

2. Broken wires

If the safety key is rightly inserted and the treadmill fails to start, you may want to check the cables for possible damage.

Solution : Unplug your treadmill from the electrical socket, and inspect the wire harness connections for loose or broken wires.

The harness connections can be found between the motor control board and the console display. In case you identify any faults with the connection, get it fixed.

3. The console display does not detect the safety key

If the wires are rightly connected, it may be that the console doesn’t recognize the safety key.

Solution: You may need to call a technician to carry out live voltage tests to ascertain if the display console still detects or synchronizes with the safety key.

If it is not detecting the key, you will have to get the console replaced.

4. The drive motor is faulty

The drive motor is controlled by the control board. In a situation where the drive motor fails to run after being activated by the control board (you will hear a buzz), this is a strong indication of a faulty motor. There is no way your treadmill will start.

Solution: Get the drive motor replaced as soon as possible if it fails to work.

5. Belt tension

If the belt is extremely tight, it could result in so much pressure that the motor might find it difficult to turn the belt.

Solution: If you conduct any form of adjustment to the belt tension recently due to slippage, you may want to check if the belt is not too tight.

Try and raise the edge of the belt to about 2 inches off the walking deck. If the belt is too tight, you might find it difficult to lift it up to that level.

You can loosen the belt by following the steps as indicated in your user’s manual.


6. Displaced belt

The treadmill belt can be displaced over time. This is when it shifts to either direction (left or right).

If the belt shifts or gets displaced extensively, the belt will stop moving.

Solution: Inspect the belt from the back end of the treadmill to confirm if it has been displaced. In case the belt has shifted or not sitting correctly.

You will have to turn the rear roller adjustment bolt to adjust the centering of the belt and regulate the tension.

7. Poor maintenance

Just like other machines, the treadmill needs regular checks and maintenance. The top reasons why your treadmill may fail to move is a bad belt or a faulty motor.

A damaged or poorly placed belt won’t turn as normal. In this situation, the belt needs to either be changed or lubricated.

Solution: Ensure you check the essential parts and components of your treadmill regularly.

This is the only way you can detect possible issues, correct them before they become a disaster, or render your machine idle.

The belt should be lubricated from time to time to lower the friction between the deck and the belt.

How do I know my treadmill belt is due for replacement?

Check the belt for signs of excessive wear. You can conduct this simple test by running your hand along the belt (the top and underside).

Some of the common signs of a weak, damaged, or worn-out belt include discoloration (appears almost black), and the belt becomes too smooth when you touch it.

Why should I lubricate the treadmill belt after purchase?

Before you start using your treadmill after purchase, ensure you lubricate the belt first.

This maintenance routine is recommended by treadmill manufacturers to ensure the smooth running of your machine.

This has become a common practice considering how long the treadmill might have been kept in the warehouse.

In most cases, treadmills may sit in the warehouse for months before getting delivered to the final customers.

How can I adjust a slipping belt?

If your treadmill belt is slipping away from its usual position, then you need to re-center it. You need to tighten the roller bolt on the particular side the treadmill belt is slipping to.

When a treadmill turns on but won’t run, the experience can be frustrating and tiring. Unfortunately, there is no specific reason why this may occur.

Your machine could fail to start for a few reasons, and this is not always clear until you troubleshoot and find out precisely what the issues are.

We have listed several possible reasons why your treadmill may fail to start and how to handle or correct these issues on your own.

In case you have tried all of these troubleshooting techniques, and still, your treadmill doesn’t start. You may need to invite an expert to come and have a look and get it fixed professionally.

A treadmill technician will diagnose the issues properly and get the damaged parts or components replaced accordingly.

Although the cost of repairing a faulty treadmill may be a bit expensive, it is more economical than getting a new treadmill.

Don’t just stop at fixing the issues; you can also ask the engineer to get the treadmill serviced at the same time.

A good maintenance culture goes a long way in keeping your treadmill in a good state. Maintenance can be conducted weekly, monthly, and even quarterly. Although this looks like a lot of work, it’s always worth the stress.

Remember how much you have invested in your treadmill. You don’t want to spend such a huge amount on a new treadmill anytime soon because of a lack of maintenance.
