Anything replaced or dabbled with lately? Is the console showing a negative value like -1.0? Does the motor controller day IFT on it? Thnx

PRECOR C956 power switch wont stay on


The power switch on Precor treads is also a circuit breaker. If it trips when plugged in, you have a dead short in the machine.

Precor Treadmill C956 error 21


Precor Error Code 21 Error Code: 21 Manufacturer: Precor
Model: All Models
Error Description: Error 21, Too many Consecutive Power Requests- The error 21 observes a treadmill's power bit reading when the treadmill was operating at speeds above 1 mph. Power bits indicate the relative time that the motor controller drive circuit is turned on. Power bits is an indication of the amount of power the load is demanding from the motor controller. Error 21 indicates that at a speed greater than 1 mph, an excessive amount of power is being demanded from the motor controller. Possible Reason:
  1. A badly worn deck and/or running belt can cause the error to appear when the unit is in use.
  2. Badly worn drive motor brushes may not be making proper contact with the drive motor commutator causing the error to occur when the unit is in use. The unit may also slow down or become sluggish when the load or speed is increased.
  3. A jumper may be required on the lower PCA if installed into a 120 VAC (Version 2) treadmill.
  4. A leaky or shorted drive motor filter capacitor (on units equipped with SCR motor controller) could increase the current demand enough to cause the error.
  5. A leaky or shorted drive motor inductor (on units equipped with SCR motor controller) could increase the current demand enough to cause the error.
  6. The high power demand is caused by a shorted or de-magnetized drive motor.
Recommended Action:
  1. Determine the amount of AC input current being drawn by the unit under no load and loaded conditions using a clamp on AC ammeter. The current displayed can be used to determine the condition of the deck and/or running belt. These same readings should be taken on a like unit, in good operating condition with a know good deck and running belt. The readings from the unit in good operationg condition can be used as the benchmark. Compare readings and replace* the deck and/or running belt if necessary. *Some units have a reversible deck. Be sure if the deck is being flipped or replaced, a new belt is installed on the new deck surface.*
  2. Inspect and repalce both drive motor brushes if necessary.
  3. Inspect the lower PCA (if unit is 120 VAC/ Version 2) for jumper. If jumper is not installed, error typically appears between 7 mph & 8 mph. Install jumper if necessary. CAUTION - DO NOT install jumper if unit is 240 VAC. Installing the jumper on a 240 VAC unit will casue the lower PCA to fail.
  4. Measure the AC input current without a load using a clamp on AC ammeter. Electrically isolate the filter capacitor from the drive motor circuit. The drive motor leads need be kept intact so the drive motor will operate with the filter capacitor removed from the circuit. Re-measure the no load AC input. If the AC input current is significantly lower, replace the filter capacitor.
  5. Measure the AC input current without a load using a clamp on AC ammeter. Electrically isolate the inductor from the drive motor circuit. The drive motor leads need be kept intact so the drive motor will operate with the inductor removed from the circuit. Re-measure the no load AC input. If the AC input current is significantly lower, replace the inductor.
  6. Swap the existing drive motor with a known good drive motor.

What is the problem on a C956i when error code 15 comes up? Can this be fixed by the user or does it require a professional?


Precor Error 15, AC Input Voltage Too High Probable Cause 1. AC input voltage is incorrect.
2. AC input voltage transients. Transients can be caused by lightning strikes or by other pieces of equipment sharing the unit's AC power.
Corrective Action
  1. Verify AC feed into the building's circuit breaker is correct and connected to the proper transformer tap.
  2. Ensure the AC grounding for the unit's outlet is good and verify the unit is connected to an isolated and dedicated 20 amp circuit.

What does Err26 mean?


Precor Error Code 26 Error Code: 26 Manufacturer: Precor
Model: All Models
Error Description: Error 26, Motor Pulse Width Incorrect - Observation of the speed sensor signal and verification the signal from the speed sensor is appropriate for the requested speed. If an incorrect or erratic speed sensor signal is detected the error appears. Possible Reason:
  1. The line of sight between the speed sensor and the speed sensor target is obstructed.
  2. Incorrect gap between the speed sensor and the speed sensor target.
  3. Incorrect adjustment of the speed sensor potentiometer (when equipped).
  4. Damaged speed sensor target.
Recommended Action:
  1. Using a static safe vacuum cleaner, carefully vacuum out the drive motor compartment. Be sure to thoroughly clean the area between the speed sensor and the speed sensor target.
  2. Inspect the gap of the speed sensor to the speed sensor target. Proper gap is 3/16" and the speed sensor photo eye should be aimed at the larger portion of the targets wedge shaped section. If unit has a magnetic speed sensor, the gap between the end of the sensor and the flywheel tooth needs to be 3/16".
  3. Locate the speed sensor potentiometer (when equipped) on the lower PCA. Set the speed sensor potentiometer to mid-range. Start the treadmill and increase speed to 6 mph. Carefully adjust the speed sensor potentiometer until the treadmill is operating the smoothest. Increase the speed to full speed and again adjust the speed sensor potentiometer until the treadmill is operating the smoothest. These two adjustments are typically small and are generally only a matter of fine tuning.
  4. Inspect the speed sensor target for any scratches or tears that could cause incorrect readings. Replace the speed sensor target if necessary.

I have a C956 treadmill. I am getting error code 44, can you tell me what that means?


Precor Error 44, Un-commanded Lift Motion Probable Cause 1. Intermittent or bad connection in the lift position sensor(potentiometer).
2. Lift position sensor (potentiometer) is bad.
3. Lower PCA is bad.
Corrective Action
  1. Bad or intermittent connection of the lift position sensor (potentiometer) is the most common cause of the error 44. Inspect all wiring and connections related to the lift position sensor (potentiometer). Repair or replace wiring connections as necessary.
  2. Monitor the lift position number displayed while operating the lift in diagnostics mode. If the reading makes large changes or is erratic, the lift position sensor (potentiometer) is likely bad. Replace the lift position sensor (potentiometer) or lift motor if the lift position sensor (potentiometer) is internal to the lift motor.
  3. If the lift moves without any command entered either manually or through a program, replace the lower PCA.

The tv on my treadmill has lines through it,


Your problem is the three capacitors which are located beside ic50. Yhey are 100 / 22 and 10uf.
The ESR will be high. Change all three and your up and running.

C956 precor treadmill


Hi
not to sound funny but are you sure that you have this tread set in the units (mpg/kph) that you require. i have worked in loads of gyms and its a common problem that people think the belt is running to fast because its set in kph and that thinks its in miles eg 9mph = 14.5kph
you can check and change the units in the club setting menu.
hope this helps :)
