Question

What is wrong if the motor on my treadmill is fine, and everything on the panel works, but the walking belt will not move?

Community Answer

Mine did the same, but blew the main fuse. I traced the fault to a damaged component on the motor main board. You might have a damaged motor control board which can be repaired if you look online.

Question

Where are the fuses located on a treadmill?

Community Answer

In the fuse box, but some treadmills put them in the plug if you live in the UK. Anywhere with a two-pin plug tends to not have a fuse, so you need to manually discharge the treadmill.

Question

What do I do if my treadmill is speeding up on it's own?

It's likely a problem with the speed control module/circuit. Contact the manufacturer or seller, or a reputable repair shop.

Question

What should I do if my treadmill is blowing fuses?

Community Answer

If you've already replaced the fuse several times, and the new fuses continue to blow, there's something wrong with the treadmill itself that needs to be addressed. You'll want to find an electronics technician at a local repair shop who can assess the problem.

Question

My treadmill runs and there are no error signs, but when I am walking on it at a steady pace then the belt will start to slow down. What can I do?

Community Answer

Your best bet is to either get the belt checked out by a professional or replace it. Try seeing if there is hair or something that is caught in the belt.

Question

My treadmill is running at an erratic speed when it's turned on. What could be the problem?

Community Answer

Your motor speed control switch/circuit is likely the issue. If your treadmill has a speed control knob that you turn, it's normally a simple replacement of the potentiometer switch and knob and is fairly easy for anyone to replace -- just be sure you have the power disconnected before you begin the repair. If your treadmill speed control is a digital display/button that you press to speed up/down, then you're looking at determining whether the speed control circuit is working correctly. In this case, there are some decent online videos on the topic, or you could take it to a service center.

Question

What is causing my treadmill to suddenly stop while I'm working out?

Community Answer

You may have blown a fuse or circuit in your house. The treadmill itself may have a problem with its power connection or wiring.

Question

My new treadmill doesn't work; it displays e1 error code. There is no smoke or sound coming out from the motor. What can I do?

Community Answer

The E1 error code on a treadmill is generated when there speed error in treadmill. There can be possibly three reasons for this: 1) Mistake in the belt (looseness, over tightness, breakage). Anything that is causing the treadmill not to rotate will create this fault. 2) If your treadmill starts rotating then stops with fault then you can check the speed sensor mounted either left or right side of front drum of treadmill. Check if there is any damage on the sensor or cable damage or if the distance between sensor and drum is adequate. 3) If any of the above two are not the reason, then there's fault on the main card of the treadmill. Call a company service engineer who will know how to handle it.

Question

I smell something burning when I am using the machine. Does the motor on the treadmill need to be replaced?

Question

When I start my treadmill, the belt does not move. I have to push with my feet to get it going. Once it is going, all is well. How can I fix it?

Community Answer

Sound like the motor is going bad or the power supply is not sending enough power to the motor.

Question

My treadmill runs just fine, except that it will not raise and lower (incline); it gives an error message, but no sound or any other indication. What could be the problem?

Community Answer

There could be a problem with the motor/pulley/system that runs the incline. Checking the owner's manual may help.

Question

Why does my treadmill speed up by itself?

Community Answer

It's likely the speed control module/circuit. If you have the knob style that you turn to speed up/slow down, you probably need a new "potentiometer" switch. If you have a digital control for the speed, you'll need to determine if there's a problem with the speed control circuit.

Question

How do I adjust the belt?

Community Answer

Look up the manual online. It should tell you how to do it. My treadmill has bolt heads that you have to turn on each side of the belt.
