Hi, my Precor 9.21 treadmil was working fine,

Unplug unit remove motor shroud take a look at incline motor frame assembly, by the sound of it maybe metal fatigue failure disengaging the incline motor itself and could have damage it. This would be my best guess if so contact Precor.

My Treadmill shuts down after 10 mins on it. Can

If you have not ever lubricated the running deck then I suggest doing so . What happens is that the lack of lubrication will tend to make the belt drag or stop . The lower board will register a excessive current thus shutting down. If the lubrication does work then you may need to replace the running belt and flip the deck if this process has never done.

Same problem

I would suggest that you reattach the two wire that their because the unit is pull too much current and that safety feature is to protect both motor and lower board from damage. If you have not been instructed by your local dealer about preventative maintenance Most Precor running are double sided, which means both surfaces are usable and are coated with wax. The easiest way without dismantling your unit is to follow this procedure:
You may purchase this wax product @ http://www.gympart.com/ or call them 1-800-496-7278 I would recommend what is call WAX BLAST they come in 3oz or 6oz bottles.
Now the fun part to apply this product you must first get the treadmill and walk on it for about 5min to heat up the deck, then stop the unit with your product go to upper third of the belt lift edge of the belt stick the nozzle between the belt and deck squeeze the bottle approx. amount 1 tbs of wax to the center then get back on the treadmill and walk for 10 min this is to heat up the wax so that belt will act like a wick to absorb wax! This should be done every 3 months or so. Their a catch if this does fix the problem you may be investing in a new belt and possible and new deck. Hope this take of it!!

Back dust coming from drum

This is telling you that the running deck which has a black phenolic surface is literal being sanded off the particle board you will need to have both belt and deck replaced, because like doing a brake job you don't replace the pads without turning the rotors that if you want it to last longer and be safer.

Overheating??

If you are able tho rest it then I suggest this procedure as I have for all Precors: Sounds like the wax lubrication has finally boiled off the belt, the easiest way eliminate this problem is to rewax the deck.

Can you tell me what Err22 is? Thanks!

Description
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.
Possible Causes
1. The treadmill utilizes an optical (infrared) speed sensor and the line of sight between the
speed sensor and the speed sensor target is obstructed.
2. Drive motor brushes are bad.
3. The speed sensor position relative to the speed sensor target is incorrect.
4. The speed sensor potentiometer adjustment is incorrect (when equipped).
5. The speed sensor is inoperative.
6. The lower PCA is bad.
7. The lower PCA to upper PCA interconnect cable is bad.
8. The upper PCA is bad
Possible Remedies
1. 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.
2. If the motor brushes do not make sufficient contact with the motor commutator, the drive
motor will not start when drive voltage is applied. Replace both drive motor brushes.
3. 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.
4. 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.
5. If the speed sensor in inoperative the drive motor will start and run briefly before the error 21
occurs. If it is possible to access the speed sensor wiring, measure the D.C. voltage between
the speed sensor leads Two of the leads will constantly read approximately 5 Vdc. Two of the
leads will toggle between 0 Vdc. and 5 Vdc. as you slowly rotate the speed sensor target. If
you do not see both measurements above, the speed sensor is inoperative and must be
replaced. In some cases the speed sensor is mounted on the lower PCA and the the lower
PCA must be replaced.
6. Substitute a known good lower PCA to determine if the lower PCA is bad.
7. Substitute a known good interconnect cable for the existing cable.
8. Substitute a known good upper PCA to determine if the upper PCA is bad.

Belt slips when machine is cold...but runs normal

tighten the belt, by adjusting the two bolts on the rear roller. Adjust both sides equally a 1/4 clockwise turn at a time. This will take up the slack and is safer to use

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.
