Precor 9.35 Treadmill - Page 7 - Answered Questions & Fixed issues

I HAVE A TREADMILL AND I HAVE ERR1 WHEN I SWICH IT ON. DO YOU HAVE ANY SUGGESTIONS?

Usual cause is roller bearings. Try to oil them they are probably rusty at worst you will have to replace roller. But this is as very good machine. Good luck

Usually wax build up on rollers. Check for lumps on track at rollers.

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. Precor Error Code 45

Precor Error LS, Speed Sensor Signal Missing Probable Cause 1. Intermittent or open connection of the speed sensor (reed switch) wiring. 2. Reed switch is defective or has intermittent connection. 3. Drive motor brushes are bad. 4. Lower PCA is bad. Corrective Action

1. Inspect the speed sensor (reed switch) wiring for damage or poor connection to the lower PCA. Replace damaged wiring or reset connection as necessary.
2. Using an ohm meter, test the reed switch while rotating the drive pulley. The reed switch will close when the magnet passes in front of it.
3. Inspect the drive motor brushes and replace if necessary.
4. Test unit with a known good lower PCA. Replace lower PCA if necessary.

Be careful! I had that same problem before. The bolt came loose and I heard rubbing then the entire right arm broke off dumping me to the floor. Make sure the bolt is not broken inside the housing.

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.

Try lubricating between the deck and belt. This video will show you how to do this procedure.

I would swap the wheels and see if the noise switches to the left side. This is a common sound from a bad wheel bearing. Wheel Original Style Precor Gray PPP000000050578101 SPORTSMITH net

Lift motor is bad and needs to be replaced

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

you must replace the control board electronic.Go to www.treadmilldoctor.com and get it see the diagram how the control board control almost the 80% of the machine.God bless you

Step 1:

1)First lube the deck belt+rollers bearing see the video and proceed

Step 2:

2) if the problem persistTime to replace the old board deck belt

Step 3:

3) You must tesst the maim motor bearing+ drive beltsee my personal TIPS for motor helps, and replace if necessary or repair.God bless you

try to tight the RIbbon CAble inside for keypads, and tight the upper cable vs lower cable.2) Adjust the REED swtich, test it, clean it, see the diagram, and tight very well the plug-God bless you

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 TIPSGod bless you

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 incorrect4) speed sensor potentiometer adjustment is incorrect5) speed sensor is faulty.6) lower PCA is bad7) lower PCA to upper PCA interconnect cable is bad8) upper PCA is badRemedies: vacuum the drive motor pay attention to speed sensor .b) motor brusher do not make suffciente contact repairc) adjust the speed sensor see the scheme attached.d) locate the speed sensor potentiomente on the lower PCA.set the potentiometer in mid-rangee)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 yousee the block diagram and my personal TIPS for motor in treadmills

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.ernesto cuadramanagua, nicaragua c.a.

Hi Jim:You directed this question at me, but unfortunately this isn't my expertise and I am unable to provide you with a real solution at this time. Hopefully one of other experts will be able to provide you with a real solution. Thank you for using FixYa.
