I just bought a reconditioned Precor C956 model. The motor sounds EXTREMELY loud with a low guttural sound, and with a faint tinny sound emitting from it.Also, in the schematic diagram of the motor, it shows a plate on the outside of the blue cylinder. This is missing on the unit.
The company I bought it from says it is normally a loud motor and when I held my phone to it, they thought it was OK. They will check it out if I send just the motor back, but I pay shipping and must insure. Is there anything I can do before I do this? On a scale of 1-10, I rank the noise as a 9-10. Two other people also thought the motor sounded abnormally loud.
Hat sound is due to the bearing failing inside the motor this is cause by capacitance discharge thru the armature thru the bearings. these unit can be rebulit I 've done plenty

Precor Error Code 21
Error Code: 21
Manufacturer: Precor
Model: All Models
Error Description:
Error 21, Too many Consecutive Power Requests- The error 21 observes a treadmill's power bit reading when the treadmill was operating at speeds above 1 mph. Power bits indicate the relative time that the motor controller drive circuit is turned on. Power bits is an indication of the amount of power the load is demanding from the motor controller. Error 21 indicates that at a speed greater than 1 mph, an excessive amount of power is being demanded from the motor controller.
Possible Reason:
A badly worn deck and/or running belt can cause the error to appear when the unit is in use.
Badly worn drive motor brushes may not be making proper contact with the drive motor commutator causing the error to occur when the unit is in use. The unit may also slow down or become sluggish when the load or speed is increased.
A jumper may be required on the lower PCA if installed into a 120 VAC (Version 2) treadmill.
A leaky or shorted drive motor filter capacitor (on units equipped with SCR motor controller) could increase the current demand enough to cause the error.
A leaky or shorted drive motor inductor (on units equipped with SCR motor controller) could increase the current demand enough to cause the error.
The high power demand is caused by a shorted or de-magnetized drive motor.
Recommended Action:
Determine the amount of AC input current being drawn by the unit under no load and loaded conditions using a clamp on AC ammeter. The current displayed can be used to determine the condition of the deck and/or running belt. These same readings should be taken on a like unit, in good operating condition with a know good deck and running belt. The readings from the unit in good operationg condition can be used as the benchmark. Compare readings and replace* the deck and/or running belt if necessary. *Some units have a reversible deck. Be sure if the deck is being flipped or replaced, a new belt is installed on the new deck surface.*
Inspect and repalce both drive motor brushes if necessary.
Inspect the lower PCA (if unit is 120 VAC/ Version 2) for jumper. If jumper is not installed, error typically appears between 7 mph & 8 mph. Install jumper if necessary. CAUTION - DO NOT install jumper if unit is 240 VAC. Installing the jumper on a 240 VAC unit will casue the lower PCA to fail.
Measure the AC input current without a load using a clamp on AC ammeter. Electrically isolate the filter capacitor from the drive motor circuit. The drive motor leads need be kept intact so the drive motor will operate with the filter capacitor removed from the circuit. Re-measure the no load AC input. If the AC input current is significantly lower, replace the filter capacitor.

If the AC input current is significantly lower, replace the inductor.
Swap the existing drive motor with a known good drive motor.
Precor Error 44, Un-commanded Lift Motion
Probable Cause
1. Intermittent or bad connection in the lift position sensor(potentiometer).
2. Lift position sensor (potentiometer) is bad.
3. Lower PCA is bad.
Corrective Action
Bad or intermittent connection of the lift position sensor (potentiometer) is the most common cause of the error 44. Inspect all wiring and connections related to the lift position sensor (potentiometer). Repair or replace wiring connections as necessary.
Monitor the lift position number displayed while operating the lift in diagnostics mode. If the reading makes large changes or is erratic, the lift position sensor (potentiometer) is likely bad. Replace the lift position sensor (potentiometer) or lift motor if the lift position sensor (potentiometer) is internal to the lift motor.
If the lift moves without any command entered either manually or through a program, replace the lower PCA.
The switch is also a circuit breaker it tells me that their is a good chance your Motor Control Board is shorted and will need to replaced or can be rebuilt.

Hi
not to sound funny but are you sure that you have this tread set in the units (mpg/kph) that you require. i have worked in loads of gyms and its a common problem that people think the belt is running to fast because its set in kph and that thinks its in miles eg 9mph = 14.5kph
you can check and change the units in the club setting menu.
hope this helps :)
