Precor 935 Premium Series Treadmill Questions & Answers
What is an Error 22, 23,and 26 on a precor 9.35?
Error 22 indicates that the drive motor (running belt) has been instructed to start, by either manual or program control, and the monitoring system has not received any response from the speed sensing system indicating that the drive motor has started.
Error 23 indicates that the speed sensor signal was lost while the treadmill was in operation
Error 26 this error monitors the speed sensor signal and verifies the the speed sensor signal is appropriate for the requested speed. If the speed sensor signal is incorrect or erratic an Error 26 will be displayed.
Unplug unit and remove motor shroud and try these procedures:
The treadmill utilizes an optical (infrared) speed sensor and the line of sight between the speed sensor and the speed sensor target is obstructed.
The speed sensor position relative to the speed sensor target is incorrect.
The speed sensor potentiometer adjustment is incorrect (when equipped).
The speed sensor target is damaged
Carefully, vacuum out the drive motor compartment with a static safe vacuum cleaner. Pay special attention to the area between the speed sensor and speed sensor target.
Adjust the speed sensor position so that the space between the speed sensor and the speed sensor target is 3/16 inch and so that the speed sensor photo eye is aimed at the larger portion of the targets wedge shaped section. On hall effect speed sensors (magnetic sensor)
the space between the end of the speed sensor and the flywheel tooth should be 3/16 inch.
If the treadmill utilizes a speed sensor potentiometer, locate the speed sensor potentiometer on the lower PCA. Set the speed sensor potentiometer at mid-range. Start the treadmill and increase the speed to 6 mile per hour. Carefully adjust the speed sensor potentiometer to the point where the treadmill is operating the smoothest. Increase the treadmills speed to full speed at repeat the previous adjustment. These two adjustments are typically small and are usually only a matter of fine tuning.
. Most speed sensor targets consist of a circular arrangement of alternate black and silver sections. If the speed sensor target is torn or badly scratched the speed sensor may receive an incorrect reading. Replace the speed sensor target.
My Precor 9.35 treadmill keeps shutting off. At
Is it on an extension cord? Take it off any extension cords and make sure it's on a dedicated 120v circuit. No other items on the circuit. Also, how old is it? Precor made a bunch of the 9.3x series from 2002-2005 with an aluminum tail roller that can cause problems. Check the back roller. Is is silver and non-magnetic? if that's the case, you have an aluminum roller and you need to contact precor. If you're the original owner of the machine, they should warranty the replacement of the parts, if not, you'll have to buy at the very least a running belt and new roller.
Precor treadmill error L5
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
- Inspect the speed sensor (reed switch) wiring for damage or poor connection to the lower PCA. Replace damaged wiring or reset connection as necessary.
- 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.
- Inspect the drive motor brushes and replace if necessary.
- Test unit with a known good lower PCA. Replace lower PCA if nec

I have a precor 935 that is showing error 5 stuck key that wont clear. any ideas
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
- 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.
- 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.
- 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.

Precor Error Code 05
L5 code after ten seconds from start up
If you have a known good speed sensor (reed switch) and you have tested it with an ohm meter (even new ones can be bad although not likely) all that is left is a motor brush issue or a bad upca. Pull the motor brushes and see if they still have life in them. Most brushes have lines formed in the sides to show where they need to be longer than to be acceptable. check the commutator and make sure it is clean as well. Use a stone to clean it if necessary. If all this checks out then you are looking at a bad upca.
Can you advise please
reset the machine make this: God bless you
Unplug the treadmill. Locate the console key and place the safety or reset key into the treadmill console. Replace any parts that need replacing, or is large enough to trigger with a pencil eraser or Q-tip. Plug the treadmill plug back into the wall. Use the Q-tip to press the reset button. It may be necessary to hold the reset button down for a few seconds. "CL11" will appear in the display of the treadmill.
Press the reset button one more time with the Q-tip. "CL21" should appear on the screen. Press the enter key. The display will change again and show "CL22." Keep pressing the enter key until the numbers cycle through to the number "CL26." Press enter one more time. The letter E should appear on the display screen.
Press enter twice more. The letters "SS" should appear on the screen. When this happens, press the start/stop key. Making sure to keep well away from the tread, press enter to start the treadmill. The treadmill will start on its own. The treadmill will stop on its own after a few seconds. When it stops, press the power key two times. Remove the safety key and put in a safe place.

Precor 935.i will not power
Hello,
Power issues with treadmills fit into two categories: the power
does not turn on or the power shuts off when using the treadmill. If the
power will not turn on, make sure that the treadmill is plugged into a
working power outlet. In addition, you should use a single-outlet surge
protector for the treadmill. Single-outlet surge protectors protect the
machine from any voltage changes that may occur in your home.
If
the machine is plugged into a working outlet, make sure the safety key
is in the keyhole on the console. If the safety key is not plugged into
the machine or if it is pulled out during operation, the treadmill will
not operate.
Finally, make sure the circuit breaker located on
the frame near the power cord is set to "Reset." The circuit breaker is
set to "Reset" if the top of the button is pushed in. When the breaker
is tripped, push it back to the "Reset" position and wait five minutes
before powering on the treadmill.
If the treadmill shuts
off during operation, check the power cord and circuit breaker as
described above. You can also try removing and reinserting the safety
key.
Take care.

Precor EFX 556 cross trainer slow startup
Il existe deux raisons pour lesquelles votre v?lo elliptique Precor EFX 556 d?marre lentement. Tout d'abord, un probl?me ?lectrique, tel qu'un cordon d'alimentation mal branch? ou endommag?, ou m?me une prise d?fectueuse, pourrait survivre. Un condensateur d?fectueux ? l'int?rieur de l'appareil, qui peut causer des retards au moment de la mise sous tension, est une autre explication. Pour r?soudre ces probl?mes, commencez par v?rifier les connexions ?lectriques. Envisagez d'appeler un technicien qualifi? pour diagnostiquer et r?soudre un probl?me ?lectrique ou ?lectronique si le probl?me persiste.
My precor efx556 does not detect pedaling, how can i fix it?
hello there, check if the lift control system is detected the lift is moving in the opposite direction of the issued lift command. This error would happen when the lift was already in motion (typically downward) when a lift command in the opposite direction (lift upward) was issued.
