Treadmill doesn't run...

Many problems could happen if we don't take care of our treadmill.. user's manual usually says you should give some maintenance after certain time or millage of use.. but we usually don't do it..
Anyways, I've had a couple of problems with my treadmill, which is a 5 years old Image treadmill...
Ok, we have to understand some stuff about treadmill's functionality.. In this case some parts.. Most of big treadmill have 2 controller boards, one is for the incliner and the other one for the speed of the motor.. but. there are to 'motors', one for the incliner and one for the speed in the belt..

So, if your treadmill doesn't run at all (but makes a noise like a click and it doesn't smell like burning) and your incliner works fine. . then it could be due to 2 things..
Note: you have to check if all the lights in the control panel light up when it's connected to the power supply,.. it usually does..

1. the motor controller board is burned, and you're gonna need to replace it or get it fixed. You can actually find many people on internet who charges less than 80 dls for this service.. what's the difference between getting a new one or getting it fixed?.. well.. years ago, all these boards presented a flaw of overheating too much (MC-70 Model used in most of known treadmills).. so if you get a new one (which costs around 130dls) it might get burned again.. then it's up to you..

2. the motor got stuck. This is a rare issue but it could happen, also the motor might get frozen.. which is also unusual but it happens.. In this case, you can get another motor ( expensive if you buy it from the manufacturer or can find a used motor online ) or get it fixed in a electric store near to your house.. or in this case you can try to figure out what's the problem and fix it by yourself...

Let's focus in the second one.. if you think the controller board is fine, then let's test the motor in a simple way..
After unplug the treadmill, you have to get access to the motor and boards, you can use a screwdriver.. not so hard to take the cover out.. you will see the motor and 4 wires coming out from it (2 blue ones and 1 red and 1 black), unplug the red and black wires, they're the positive and negative supplies for the motor..

Now, you can use a full charged battery of any power tool (14 or 18volts recommended) you might have.. you can also use a 6volts battery but the motor will run really slow and you might need to get the belt around it out..

Just plug into the battery the red to the positive and black to the negative pole.. and you'll see if the motor starts to run.. if you hear any click noise from the motor, that means the motor could be stuck.. so try to move manually the weel next to the motor, the one which is attached to the belt where you run.. if it doesn't, then there's something inside that's not letting the motor run. If it does move, then the problem might be electrical.. and you might have to take it to a service store where they can check the brushes inside the motor..

In this case, ill explain how to take apart the motor and see what's getting the motor stuck..

Unplug all the 4 wires from the controller board.. take the motor out of the treadmill (usually is only hold by couple of crews)..

then, once is out, try to move the metal wheel to the left (the part comes off like a screww).. use extra strength if you can.. if you can't make it move.. dont worry..

Use a wrench to take the lid out.. also a screwdriver might be needed..


At this point you can see where the red and black wires are connected to, those are the brushes wich are in the lid.. so let's keep seeing inside..

Check for any rough dust or pieces of magnet around .. some pieces can be the cause for the wheel couldn't move.. as you can see the body of the motor is a solid cylinder shape magnet.. so that with the time starts to fall down.. why? i have no idea..
Once you have it most of it clear.. (even the bottom part) try to move the metal wheel and see if you can move it to the right to see if it rotates.. or to the left to take it apart..
I moved it first to the right and then i took it apart to keep cleaning the bottom part..
Then i put everything back together and tested again with the full charged battery.. and voila. it started to run.. making a noise.. but at least you know the motor can run now..
connect and install everything back in the treadmill and dont forget to calibrate it for the incliner and the speed of the motor.. (check your user's manual to do that)
I did this with my own treadmill and it worked... so if you think you have the same problem.. just give it a try at your own risk..
This could save you a couple hundred bucks.. Enjoy it..
Cheers
