Precor Error Code 22 Error Code: 22 Manufacturer: Precor
Model: All Models
Error Description: Error 22, No Motor Pulses at Start Up - Error indicates that the display has sent a command for the drive motor to start, however, the speed sensor has not returned the signal acknowledging that the drive motor has started. Possible Reason:
  1. The line of sight between the speed sensor and the speed sensor target is obstructed.
  2. Badly worn drive motor brushes.
  3. Incorrect gap between the speed sensor and the speed sensor target.
  4. Incorrect adjustment of the speed sensor potentiometer (when equipped).
  5. Inoperative speed sensor.
  6. Faulty lower PCA.
  7. Faulty interconnect cable between upper and lower PCA.
  8. Faulty upper PCA.
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. Bady worn drive motor brushes cannot make proper contact with the motor commutator, therefore the drive motor will not start when voltage is applied. Inspect and replace drive motor brushes if necessary.
  3. 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".
  4. 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.
  5. An inoperative speed sensor will allow the drive motor to start and run briefly before the error appears. If able to access the speed sensor wiring, measure the DC voltage between the speed sensor leads. Two of the leads will always read about 5 VDC. Two will toggle between 0 and 5 VDC as you slowly turn the speed sensor target. If both measurements are not seen, the speed sensor needs replaced. Some units have the speed sensor mounted on the lower PCA and the lower PCA needs replaced.
  6. Determine if the lower PCA is bad by swapping with a known good lower PCA.
  7. Determine if the interconnect cable is bad by swapping with a know good cable.
  8. Determine if the upper PCA is bad by swapping with a know good upper PCA.

The tuner inside the unit has most likely gone bad. I've seen a lot of these units do this in the last year or so. Precor use to refurbish these on site but they discontinued the program. If a tuner goes bad in one of these they want you to replace the whole viewing system now

Adjusting Tension on a Treadmill Running Belt It is necessary to properly tension a treadmill belt when it is replaced. After time, a belt can stretch and may begin to slip. When this happens, it is necessary to adjust the tension of the running belt to stop it from slipping. Manufacturers of treadmills generally agree on one of three procedures for how to tension a treadmill running belt.
  1. Adjust for no slippage of the treadmill walking belt on the front roller (Often referred to as the "Stomp Test")
    1. This procedure works well for a previously installed belt that is now slipping.
    2. Underside of belt should be free of any glazing/wax buildup.
    3. Rollers must also be free of wax buildup.
    4. Be sure belt tracking/centering is correct before proceeding.
    5. The most popular speed for this adjustment is 2mph to 3mph.
    6. Try to slow the belt by applying pressure with your foot against the belt movement while grasping the handrails. If the running belt slow, slips or stops (and the front roller does not) adjust BOTH adjustment bolts 1/4 turn clockwise. Test again and repeat adjustment if necessary.
  2. This procedure requires two belt gauges or calipers
    1. This procedure works well when installing a new belt.
    2. This procedure requires you to stretch the belt. Depending on the manufacturer*, this varies between .4 and .6 percent. A dial on the gauge or caliper will indicate the amount of stretch. *Consult the owner/service manual for proper tension.
    3. If you are working on a previously tensioned belt you will need to release the tension before attaching the gauges or calipers.
  3. Gauges or Calipers unavailable
    1. Release the tension on the belt.
    2. Using a yard stick or tape measure, place two marks on the left and right edges of the belt and deck 36 inches apart (or 50 inches if you prefer).
    3. Adjust the left and right tensioning bolts until both sides measure 36 3/16 inches (or 50 1/4). This is equal to .5% of stretch.
    4. Test for proper tracking and tension, adjust if necessary.

Please read my personal TIPS for treadmills and test it.
However LUBE inmediately the deck belt, this happen because the lack of maintenance by 5 hours aprox, So the system protect itself for electronic system and shut down.
2) LUBE the rollers bearing too.
3) Test the main motor bearint, measure the input voltage motor, if there are the motor is faulty. Repair. see my personal TIPS

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

I have a ProLife treadmill with a breaker on it, the fuse may have blown it. You may try that, It would be next to the switch by the front of the the power cord. The front on the pic of this website, near the left bottom of cord or switch.

It is the aluminum rollers they used in manufacturing. Precor will replace the rollers with steel and the belt for labor only (it was about $80 for me in Idaho) It has worked like a champ since.

Der Sir;
The power switch is failure , you must Change the switch. You must be shure the some wires is Not loose, otherwise the wires will be touching the carcase causing the spark inside. Retight the wires or solder .You must inspect the main motor board and all the element around . If someone is burned or other wires is touching the carcasing producing the spaprk.
sincerely. God bless you.

CHeck the fuses on the lower board. You may also want to unplug the eddy current magnet and speed sensor from the lower board and the heart rate sensor(if there is one) from the upper board to make sure they are not shorted out and not allowing the upper to light up.
