My kettler tx1 marathon running machine causes the electricity to swith off in the house. This occurs when I start the treadmill, not when I simply switch it on. Any idea as to the cause?


The motor or the Motor control board is faulty. Can be the motor brush or the shorted igbt transistor in the motor contol board. If you wish to get some more details about treadmill repair then check the following link.

Lg 32pc51 PSU shorted


Please replace the power board as card basis. It will be best, rather than trying to repair it. You'd lose both money and effort.

My nikon coolpix l110 is now dead. not powering on. 300v dc is shorted with the gnd. IGBT is short. what to do


Fixya does not provide manuals of any kind. If you are unsure of what you are doing, you should take it to a reputable repair facility.

When I put the key in, the treadmill belt goes really fast. Its like its stuck and I can't turn it down the knob keeps popping off. Do I need to get it serviced.


hi,
You have to check the Driver circuit board for the motor. There is motor control IGBT Insulated Gate Bipolar Transistor) in this board .If the IGBT is short then the treadmill will try to run at high speed without setting any value or witout pressing the start button. You have to check the OHMS between the seocnd and third of lead of the IGBT. If it shows less than 100 Ohms then the IGBT is short and you have to replace the same. Also you have to check the connection to the control pannel. Is there is any loose conatct. Remove the connection in the motor control board which go to the control pannel and reconnect it. Also check the speed sensor. In most of the treadmill you can find the speed sensor near the motor pully. Remove the speed sensor and clean it and the refix it. Remember one thing remove the power of the treadmill and leave it for 30 minutes then only oppen the treadmill. Because there is high voltage storage capacitors in the motor control board which will hold charge for some time even after the power is disconnected. i ahve added the picture of IGBT for your refference

ok

I have a image 17.5 s when i press start the treadmill belt will start and then turn off. i already check the motor with a 18v battery and it work find. could this be the motor control?


hi,
First of all you hve to check the speed sensor near the motor pully. Clean the speed sensor and check the treadmill. I the problem remains then You have to check the Driver circuit board for the motor. From your naration the motor is ok . Why the circut breaker trips because, if the IGBT( insulated gate bipolar transistor) is short then, when you press the start button the motor will try to drain a high current from the power line.IGBT controll the voltage to the motor.When it get shorted the applied voltage will go to the motor without regulation. Also you have to check the rectifier diode. The IGBT will look like one in the picture. Check the ohms between the seond and third pins of the IGBT. It should be above 1 kohm. Remember one thing remove power before oppening working in the treadmill. Because it have live area all over the driver board.
ok
