Precor 9.27 Control Portion Not Turning On

Recently I was sprinting on my treadmill when it shut off on its own suddenly. I turned it back on but only the on switch was activated. The control board at the top refuses to turn on. I do not know what is wrong with it. Please help.

1) Reset the c.breaker from your house
2) See the c.breaker or blown fuse in your treadmill see the block diagram +c. diagram
3) Try again, and proof.
4) Test the main switch from treadmill, and replace if necessary for OPEn, see the diagram how to do it.
God bless you

SOURCE: Err 22 keeps displaying on control panel

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
Error 45 :The lift control system has detected that the lift is moving in the opposite direction of the issued
Possible Causes 1. Lift Motor hysteresis. 2. Bad lower PCA
Possible Remedies 1. This error would typically happen when the lift was already in motion (typically downward) when a lift command in the opposite direction (lift up) was issued. Some motors exhibited a very long turn around time and the lift motor would still be moving in the original direction (downward) while the control system was attempting to move the lift in the opposite direction. If the error 45 condition is persistent, replace the lift motor. 2. This is a very rare condition, if the lift moves in the opposite direction of the issued lift command, replace the lower PCA lift command.

SOURCE: My Precor 9.21 si Treadmill shuts down upon

Hey Doug,

Just wondering has this unit ever had the running deck flipped over if not this may be sighs of worn deck or belt or both! What is starting to happen is that at the higher speed the unit is starting to draw more current, so the motrol control board will sense this and will shut down so it won't damage either the motor or board. What starts as an occassional shut down will progressively become more frequent. Simple test is put your hand palm down between the belt and deck,if you feel uneven ridges then the deck needs to be flipped over and when you pull out your hand out and their is a black sooty film on the back of it ,then that seals it this means that the composite material is being shaved off. Most likely the belt will have a smooth glazed feeling in the middle part of it. and well also need replacing.

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.

Error 27


Precor Error 27, Too Much Drive Motor Current Probable Cause 1. The running belt and/or deck are badly worn.
2. Drive motor is shorted or de-magnetized causing a high power demand.
Corrective Action
  1. Check the amp draw using a clamp on AC volt-amp meter during loaded and no load conditions and compare values to a similar treadmill that is known to have a good running belt and deck. Replace the belt and/or deck if necessary. Don't forget, some units have a double sided deck which means it may be flipped over rather than replaced if it has an unused side.
  2. Test unit with a known good drive motor. Replace drive motor if necessary.

Precor 927 stuck in incline position


How long have you let it run for after turning it back on ? Some treadmills have a re calibration test built in and will incline to the max and work its way down. During this time you should simply walk away and not touch anything as it trys to calibrate its self. If not i will need more information on it

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.
