SOURCE: the resistance on my Precor elliptical 5.17 will

There is a small motor under the shroud that operates the resistance motor. It is about the size of a roll of half dollars. Have someone use a meter and check that you are getting power to this. When you turn on the machine the motor should move the resistance forward then back. You can hear this everytime you turn it on.

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

How do I solve error 42?


Precor Error Code 42 Error Code: 42 Manufacturer: Precor
Model: All Models
Error Description: Error 42, Lift Position Value Out of Range. Error 42 is displayed when the lift position reported by the lift position potentiometer is found to be outside its set limits.
If an Error 42 has occurred, it is important to know the physical position of the lift when the error occurred. It is possible the lift is physically out of range or jammed. In this case, the Error 42 is a secondary symptom and the issue should be approached as an Error 40. Possible Reason:
  1. Bad or intermittent connection in the lift motor controller.
  2. The lift motor requires calibration.
  3. The lift motor potentiometer is bad.
  4. The lower PCA to upper PCA cable is bad.
  5. The lower PCA is bad.
  6. The upper PCA is bad.
Recommended Action:
  1. Intermittent connections can be difficult to locate. If the Error 42 condition is intermittent, a connection issue is probably the cause. This is definitely true if the Error 42 occurred while the lift was within its normal physical range. Inspect the lift potentiometer connector and repair connection if necessary. If the intermittent connection cannot be found or corrected, replace the lift motor. A lift calibration number of 0 or 255 indicates an open or shorted potentiometer connection. This means the problem could be anywhere between the lift motor and the upper PCA. Typically it can be identified and tracked using an ohmmeter.
  2. Using the appropriate service manual for the unit being tested, refer to the lift calibration procedure. If the information in the service manual doesn't match the lift position/physical lift position of the unit, recalibrate the lift motor. [Something caused the lift motor to be out of calibration. Investigate for cause and correct. Simply recalibrating the lift motor will not solve the problem.]
  3. If the lift calibration number is not 0 or 255 and does not change when the lift motor turns, replace the lift motor.
  4. Check continuity of the interconnect cable or swap with a known good interconnect cable to verify if cable is bad.
  5. Swap the lower PCA with a known good lower PCA to verify if the lower PCA is bad.
  6. Swap the upper PCA with a know good upper PCA to verify if the upper PCA is bad.

ERROR 46


Precor Error 46, Low Battery Voltage (AMT12 Only) Probable Cause 1. Blown fuse in the positive battery wire of the AMT12 2. Faulty or poor connection on the battery or LPCA 3. Low or no output voltage from battery
Corrective Action
  1. Remove the power from the unit and move the lift fuse from the in line fuse holder on the positive battery cable
    • Measure the fuse with an ohm meter (multi meter), the fuse should read approximately 1 ohm or less
      • If the reading is significantly high, replace the fuse
      • If the fuse is open, refer to next solution before you continue
  2. Check connector of the battery cable for shorts or poor connections
  3. Enter the diagnostic program per procedure, P80 Settings or Accessing the P30 Diagnostic Software
    • Using the diagnostic program allows you to test the incline system without continuously pedaling the unit if you have an external power supply
      • Otherwise, you will need to continue to pedal the unit
    • Connect a DC voltmeter to the J3 connector on the lower PCA as follows:voltmeter common lead to terminal 3 (black wire) and voltmeter "hot" lead to terminal 2 (red wire)
    • Using the STRIDE HEIGHT Up and Down keys, operate the incline
      • The voltmeter should read about +12VDC when the incline is instructed to move upward and about -12VDC when incline is instructed to move downward
    • If either voltage measurement is significantly low, replace the battery

Precor efx 546 wobbles when raising incline


It may be either the front shroud is installed incorrectly or broken, or the corkscrew for the incline motor is bent. If it is bent, it would need to be replaced.

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.

Efx 546 in diagnostics mode, flashes 255 and then real position of incline. getting error 42 when first turning machine on.


ok

elevation needs calibration or stuck


open--put elevation manually lowest and turn the unit on and bring the elevation lowest by pressing el down key

put it together clear it and start elevation will come in the starting position clear it and use it 225 is out of range of elevation

also check elevation fuse if it is good and secure

Elevation has gone too high. foot rollers are hitting front plate


Precor Error E4, Incomplete Initialization Probable Cause Indicates that an incomplete upper PCA to lower PCA initialization occurred. When this error occurs, all lift motor and drive motor motion is ceased and the display will go blank except for the error displayed.
Corrective Action Run the initialization program. Caution: The treadmill's running belt will accelerate to the treadmill's maximum speed (12mph). DO NOT stand on the treadmill's running belt during the procedure.
  1. Set the on/off switch to the OFF position. Wait a minimum of 10 seconds to allow the internal power supply to discharge.
  2. Remove the safety key from the console and set the on/off switch to the ON position.
  3. Press INCLINE UP and SPEED DOWN keys together. While pressing these keys, replace the safety switch on the console. Continue holding the INCLINE UP and SPEED DOWN keys until the display goes blank. INIT will appear in the time window of the display. The EEPROM is now clear and reset. After a second, 1.25 will appear in the distance/calories window, 15.0 (the maximum incline) will appear in the incline window, and 12.0 (the maximum speed) will flash in the speed/pace window.
  4. Press QUICKSTART to begin the speed calibration process. Power bits will appear in the incline window, the target speed will appear in the time window and the actual speed will appear in the speed/pace window. At the beginning of the process, the target speed will be .5mph. The running belt will start. Once the actual speed reaches .5mph, the target speed will then change to 12mph and the running belt will accelerate until it reaches 12mph, then it will stop.
  5. When the running belt stops, the display will return to the user mode and the initialization process is complete.
