The incline on our Precor c964i is stuck in a high position (approx. 10% incline). Other than being on a high incline, the treadmill seems to be working fine.


Hi There,

Precor uses a pair of Triacs to drive the lift up and down. These triacs live on the lower board but are driven by the upper console commands via a serial link between the upper and lower. Most precor lift issues we see are related to the lower board but with Precor it could be an upper board or the CPU Chip that resides on the lower board or a failed Triac. Good Luck

Replace any parts that need replacing, or is large enough to trigger with a pencil eraser or Q-tip. Plug the treadmill plug back into the wall. Use the Q-tip to press the reset button.

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

Client run on treadmill then suddenly its stop and display an error speed, then 5 seconds treadmill belt moves again and moves faster whats the problem of that?


hi,
There are two possibilities for this problem
1. Check the speed sensor on near the motor pulley. Remove the sensor and clean it and re-fix it. then make a try. if problem remains then
2. The motor speed controller is faulty. There is an IGBT for controlling the motor speed. If it get shorted the motor will run it its high speed.

Be sure before opening the treadmill remove the power.
ok
