Common Treadmill Problems and How to Fix Them

What are the most common treadmill problems, and how to fix them? This common question about treadmills are the ones our experts hear the most often from our customers. Like most exercise equipment, a running treadmill may undergo many technical problems over time, primarily if you use it frequently/abuse it over the years. All treadmills undergo almost the same type of problems, and compromise can lead to more problems. 

Fixing the common treadmill problems at an early stage of development saves the breakdown time and keeps you away from an accident. So, we have decided to assist you by offering solutions to some of the most common treadmill problems you may encounter while using treadmills.

Here are some of the most common treadmill problems and how to fix them. Let’s have look at them one by one.

Burning Smell from Treadmill

During workout on treadmill, if you experience a burning smell, turn off the machine immediately, get down and unplug the power cord. 

This smell may be due to the very high friction between the belt and the deck or a short might take place in the wiring, electronics or motor. These problem may lead to a fire, so call an expert technician to repair it immediately.

Erratic Speed in Treadmill

When your treadmill isn’t properly set on the ground, it’s one of the main causes of irregular speed. The speed can become erratic as a result of this imbalance.

Another aspect to consider is plugging your machine directly into a 20-ampere socket in the wall. Try to avoid a surge protector or stabilizer, as well as an extension cord. 

If the above two are in place, search for further discrepancies like loose connections, insufficient lubrication on the treadmill belt, or simply worn out treadmill components like the belt and motor. Use high quality silicon lubricants or treadmill lubricant alternatives for proper lubricating of the belt.

Read user manual to set recommended speed. Set the treadmill to this pace and pay attention to how the treadmill moves.

If the machine totally shuts down, the issue is most likely with the motor or a bad circuit. On the other hand, if you discover a problem with the belt, you should replace it right away. 

Slipping Belt On Treadmill

If you find yourself slipping on the treadmill, there is most likely a problem with the belt. Take this slipping sensation as a sign that your treadmill is in need of some little maintenance.

When there is too much friction or the belt is excessively tight on a treadmill, the belt tends to slip. A slipping belt problem might also occur if the belt is excessively loose or has too much lubrication .  

To solve it, align and tighten the running belt. LIVESTRONG recommends a simple rule while tightening the belt: you should lift the belt in the center & keep 2 to 3 inches gap between the belt and the machine’s body. 

Treadmill Display Not Working

This is one of the most common treadmill problems now a days. There are a few troubleshooting actions you can take if your treadmill display not working (won’t turn on). 

You should make sure your treadmill’s power wire is securely plugged in. If your treadmill display is powered by batteries, check to see if the battery needs to be recharged or replaced. If nothing of these methods work, unplug your treadmill for 1-2 minutes before reconnecting it. This might repair the problem by resetting the internal circuit breaker.

A magnetic flywheel may have fallen off or need to be replaced if your treadmill relies on it. If everything else doesn’t work, you might need to call a repair technician to fix problem.

Heated Treadmill Belt

An excessive amount of friction on the running belt could be the source of this problem. When the friction reaches a specific level, the machine shuts down automatically. 

You need to fix the problem immediately by lubricating it properly. If the problem is not resolved after lubricating it, replace the belt with a good quality walking belt

Don’t split any lubricant on the walking or running platform, since this may create slippage during later workouts. Pull up one side of the belt and place the silicone spray nozzle beneath and in the central region.

Treadmill Motor Problems

The treadmill’s motor generates the required electromotive force through a transmission belt that links to the tread, which allows the runner to conduct various workouts. There are several different types of motors, Permanent Magnet Direct Current (PMDC) type being the most common for home treadmills. The voltage ranges are easily controlled and vary from 80 to 260 volts.

These motor problems could be due to anything from faulty belts in the motor, breakdown of the mechanical parts, or issues with the chip in the motor that controls the speed.

Replace the faulty belts with good quality motor belt. 

Treadmills that run into full speed often face problems with the failed circuits. The motor sometimes require to be fully replaced. 

Non-working treadmill motor can be expensive to the owners. It is really difficult to diagnose the particular problem of the motor and troubleshooting it by yourself. It’s better to hire a professional to inspect and replace the treadmill motor if necessary or parts of a problematic motor.

Turn On/Off Problem of Treadmill

This is one of the common treadmill problems that it refuses to power on or off sometimes. It is plugged into ground fault current interrupter, an outlet that has tripped off. Reset it and turn again. 

If the power of the outlet is live, then check the console powers. If the console power is not on, then take away motor hood to check loose pin connections or unattached wires. 

Alternatively, unplug the plastic connectors and again plug it to check the fixation.

Elevator Does Not Function in Treadmill

This is frequently the result of a motor malfunctioning and requiring immediate service or replacement. 

Furthermore, sloppy connections may contribute to this problem; therefore, ensure that the connections are sufficiently tight.

Treadmill Speed Sensor Problems

The treadmill belt’s revolutions per minute are converted into miles/kilometers per hour via the speed sensor. 

The speed display may display an error code if there is a problem with the speed sensor or if it is just loose. Rather than calling a technician to just tighten the connectors, you can see if the speed sensor has just come loose or whether the sensor has a problem.

To examine the speed sensor, disconnect the treadmill first. Trace the black and white wires to the circuit board below after removing the motor cover. The wires should then be removed from their terminals.

Finally, unscrew the nuts that secure the motor to the mounting bracket and push the motor away from the front roller pulley from the opposite end. This should allow you to remove the belt with appropriate slack. Then raise the motor to have access to the speed sensor and mounting bracket under it.

Check that the speed sensor is properly attached to the bracket; if it isn’t, tighten the screws to fasten the bracket even further. Then follow the sensor’s lead wire to the circuit board below. 

A voltage meter can be used to check the wire’s continuity. The sensor must be replaced if the meter displays continuity. Replace the speed sensor of the treadmill if necessary, then reverse these instructions to rebuild the treadmill. 

Consult your owner’s handbook for instructions on how to reset and re-calibrate the treadmill after it has been reassembled.

Summary

These are some of the most common treadmill problems, and fixing these problems is not always straightforward. Troubleshooting may help you determine the leading cause of a breakdown and allow you to change or repair treadmill parts with or without the assistance of a technician. It’s essential to take safety precautions when troubleshooting your treadmill.

Lastly, if you don’t have enough knowledge and confidence to fix a specific problem, do not attempt to repair them by yourself. Removing or improperly replacing parts can cause irreversible damage to your treadmill. This might also present other risks like a fire hazard or danger to anyone using the treadmill.

FAQs

What can I do when treadmill doesn’t work & displays e1 error code?

When there is a speed error on a treadmill, the e1 error code is displayed. There could be three reasons for this: 

1) An error in the belt; (looseness, over tightness, breakage). Anything that stops the treadmill from moving is to blame for this problem.

2) If your treadmill begins to rotate but then stops due to a malfunction, check the speed sensor located on the left or right side of the treadmill’s front drum. Examine the sensor for any damage or cable damage, as well as the distance between the sensor and the drum. 

3) If neither of the preceding two are the cause, the treadmill’s main card is faulty. Call a company service engineer who will know how to handle it.
