The motor controller weakens over time because of the excessive amperage draw of the motor do to lack of lubrication (which wears the walk belt and walking deck).
Take an amperage reading of the motor it should be 2-3 amps with no one on it, with someone walking on it it should be around 6-12 amps. I would bet yours is elevated above 6-12 amps.The controller is dropping output because of the friction problem.
The first thing to try after testing the amperage is to lubricate the walking platform. Then retest and see if the amperage comes down and it doesn't shut off.
If it does then the next step would be to replace the walking deck. If the amperage still is up you may need to replace the walk belt second and finally if after replacing the deck and belt, if the unit is still shutting down replace the motor controller.

SOURCE: Hola Ernesto, congratulation for your seccess,, thanks for the great support you had provideded to the community. I own a precor C934 have lower Controller, LPCA problem, and I would like to check if
Thank you brother.
That causes can be
1) optical infrared speed sensor is obstructed.
2) drive motor brusher are bad.
3) speed sensor position is incorrect
4) speed sensor potentiometer adjustment is incorrect
5) speed sensor is faulty.
6) lower PCA is bad
7) lower PCA to upper PCA interconnect cable is bad
8) upper PCA is bad
Remedies: vacuum the drive motor pay attention to speed sensor .
b) motor brusher do not make suffciente contact repair
c) adjust the speed sensor see the scheme attached.
d) locate the speed sensor potentiomente on the lower PCA.set the potentiometer in mid-range
e)measure voltage D.C. for 5vdc, two fo the leads will toggle between 0vdc-5 Vdc.as you rote the speed sensor.
f) substitute a known good lower PCS for determine g) substitute a known good interconnect cable h) substitute a known good upper PCA for determine if is faulty.
God bless you
