    Thanks for responding to my question. It is appreciated. What happened with the treadmill was this: My daughter-in-law was exercising on the treadmill when she saw a puff of smoke coming from the treadmill which suddenly stopped working. We took the cover off the treadmill and examined the circuit board finding a small electronic component that had burnt out. On checking with the utility company we were told there had been a surge of power that lasted only seconds, but it would seem it was long enough to burn out one of the electronic components. My son and his wife live on an acreage where surges are a common occurrence. We have tried to find a company in the area that repairs treadmills but there are none, and the original manufacturer has gone out of business, and it also appears that the circuit board manufacturer is off shore. More than that I cannot add anything. If you have specific questions I would be happy to answer them. If we can get a wiring diagram we could determine what component has burnt out and we can replace it. Thank you. Sincerely, John Hamblin

this is indicative the some electronics components is in short circuit in the pcb. You must replace. However RUN the software calibration for diagnose, and fix it. see the block diagram.
you can measure the input voltage for the main motor if there are the motor is o.k and vice-versa
2) you can measure the output meassure from the pcb board is there are NOT the board is faulty for the input voltage motor.

Pacemaster treadmill will not start, no lights, nothing.


Is there a spot on the control board you can check for out going power? You might have a bad board. You can visually inspect your board for anything that looks burnt or one component that looks swolen or loose. Poor solder joints are a common problem with treadmills because of the constsant movement.

Hi. I have a Horizon T-62 treadmill. It stopped working during a workout and my son smelled an electrical burning smell and saw small puff of smoke. I removed motor cover and reset circuit breaker then...


Unfortunately it sounds like the motor has burnt out and would require replacing.

As this treadmills come with a 10 year warranty on the motor if you've not had it for that long the you need to contact Horizon Fitness at the link below.

If they're unable or unwilling to help you then please ask for further assistance and I'll see what I can do.

A replacement motor is in the region of $400 + fitting, but you could possibly fit it yourself.

Please can anyone help me I bought a 560hr treadmill today second hand it was workin perfectly, until my son and grandson went on it ..it now will turn on but the belt will not go it trips the power switch...


12_7_2011_9_56_59_pm.gifSee the block diagram that I did for you. Now you will see how many elements or component has the treadmills. If the fuse or breaker are trips. you must inspect and test: 1) Power cord some internal wires is touching insider and produce short-circuit. 2)Capacitor in short 3) Coil or transformer in short 4) Main Motor in short 5) Main Controller Board.

Finally see for any wire is loose and touch the chassis from the machine in that case produce a BIG SHORT. sincerely.





Good luck, G-d bless you.

How do i unhook the electrical connection from the display to the power wire?


You must watch the flexible cable or connector from display board vs Lower
Board or Main Motor Controller.
Then you must isolate the Main Motor Controller from Power Supply coming from coil or Transformer. +Pull out the fuse and turn Off.
See the block diagram that I did as people like you for yourself take carefully.


11_29_2011_4_39_37_pm.gifFinally to make short circuit in Boar or component. sincerely.

The dishwasher will not turn on


Congratulations - you found the fault !

The options you have are -
Buy areplacement board from a spares centre.
Buy a take- off board from a scrap one on Ebay.
Or - Learn about electronic repair - and identify the burnt component , buy the parts and replace it yourself.

You can take it to an electronic repair shop - if you can find one - or a electronic supply shop - and ask for a new one of "them".

If replacing a burnt component - often there is a cause other than just that component.
Experience tells you what else might be wrong to cause it.
