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.

You may have to purchase the belt from a Precor dealer in you area, if you don't have one then call Precor directly @ 1-800-347-4404 and they will help you. Most of these part have not hit the secondary market yet and Precor pretty much call the shots on whom the sell parts and support to.
There is a place on line to get some of these, it is. www.treadmilldoctor.com/Products-Services2/precor-treadmill-belt.
The manual can be found at. fitness.manualsonline.com/ex/thread/view/idThread/2141832
This place has manuals and user manulas along with support and some partswww.shopwiki.com/Precor+EFX+5.171 I believe this unit has a 10 yr warranty with it and the part in question may be covered by them. There is also a 1 year part warrant for other parts, I just don't know what parts they are covering for the 10 yr.

Reset the error code on a precor elliptical


Not familiar with an error 400 - and error 40 is an elevation error - it needs to be addressed(fixed) cannot really be reset otherwise. Check connections and fuses first. If it was recently put together, make sure the data cable was not pinched. If it is battery operated, an error 40 can occur when the battery is low.

Precor EFX 546 05 stuck key


Precor Error 05, Key Depressed at Power Up Probable Cause 1. A key is permanently depressed on the display.
2. An interface chip (IC) has failed in the upper PCA's keypad.
3. Liquid (cleaning solution or sweat) may be on the surface of a touch sensitive display.
Corrective Action
  1. Disconnect the keypad cable from the upper PCA. Reset power to the machine. If the Error 05 is eliminated, the keypad is the cause and should be replaced.
  2. Disconnect the keypad cable from the upper PCA. Reset power to the machine. If the Error 05 still appears, the upper PCA* is the cause and should be replaced. *Upper PCA's most commonly do not come with software. Remove the software (chip) from the existing upper PCA prior to replacement and install into the new upper PCA.
  3. Wipe away all liquid from the touch sensitive display. Reset power to the unit. If the Error 05 is eliminated, the liquid was the cause.

Error 45 on Precor EFX 546 Elliptical


Precor Error 45, Lift Moving in Wrong Direction Probable Cause 1. Lift motor hysteresis.
2. Lower PCA is bad.
Corrective Action 1. The error would usually occur when the lift was already in motion (usually downward) when a lift command in the opposite direction (upward) was made. Some lift motors used in production exhibited a very long turnaround time and the lift motor would still be moving in the original commanded direction while the control system was trying to move the lift in the opposite commanded direction. If the error continues to re-occur, replace the lift motor.
2. It is a rare condition, however if the lift moves in the opposite direction commanded, replace the lower PCA.
