Does the elevation work? If not, the battery is probably dead. If the elevation works fine, then it may need to be changed in the settings menu. Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/russell_1d1c35fa8a5a0be4

overlay need to replace .. first interchange the uPCB and checked

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.

Verify voltage to the MCB. If it gets power, and 2 MCBs do not light up the console, check the wiring to the console. If that looks good then it sounds like you need an upper. Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/russell_1d1c35fa8a5a0be4

I imagine if 106 people have responded then at least one may have asked if the squeak is coming from the wheels. I see it every week under warranty. the ramps and wheels need time to wear a little and until then they can be hideous. its counter intuitive being as that the ramps and wheels are supposed to be cleaned all the time. BUT, when new they make a racket and the easiest way to shut them up is a to rub a bar of soap on the ramp where the wheels travel. it shuts them up and holds a little dust over time to wear the shine off the wheels and make them act as they should. Beyond that I would need to know where the sound was coming from if not there.

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.

Precor Error Code 22

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.

Speed sensors are usually located on the motor flywh

bar soap on the ramps where the wheels travel until the shine wears off the wheels. I see it at warranty calls every week

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 Error Code 27

Precor Error 16, AC Input Voltage Too Low Probable Cause 1. AC input voltage is incorrect. 2. Treadmill operating on undersized AC wiring and/or is drawing high current. Corrective Action

1. Verify AC feed into the building's circuit breaker is correct and connected to the proper transformer tap.
2. The AC wiring must be sized to handle 20 amps of current over the loop length of the AC wiring. Voltage drop across the AC input wiring is a result of the length of the wire run multiplied by the amount of current being demanded by the treadmill. The longer the run and the higher the current the large the wire must be.Verify the unit is connected to an isolated and dedicated 20 amp circuit.

Precor Error 16

most prob one of sensor / connection gone bad

Precor Error 46, Low Battery Voltage (AMT12 Only) Probable Cause 1. Blown fuse in the positive battery wire of the AMT12 2. Faulty or poor connection on the battery or LPCA 3. Low or no output voltage from battery Corrective Action

1. Remove the power from the unit and move the lift fuse from the in line fuse holder on the positive battery cable
   • Measure the fuse with an ohm meter (multi meter), the fuse should read approximately 1 ohm or less
   • If the reading is significantly high, replace the fuse
   • If the fuse is open, refer to next solution before you continue
2. Check connector of the battery cable for shorts or poor connections
3. Enter the diagnostic program per procedure, P80 Settings or Accessing the P30 Diagnostic Software
   • Using the diagnostic program allows you to test the incline system without continuously pedaling the unit if you have an external power supply
   • Otherwise, you will need to continue to pedal the unit
   • Connect a DC voltmeter to the J3 connector on the lower PCA as follows:voltmeter common lead to terminal 3 (black wire) and voltmeter "hot" lead to terminal 2 (red wire)
   • Using the STRIDE HEIGHT Up and Down keys, operate the incline
     • The voltmeter should read about +12VDC when the incline is instructed to move upward and about -12VDC when incline is instructed to move downward
   • If either voltage measurement is significantly low, replace the battery

I would definitely check the battery first. The battery may not have enough charge to power everything plus the lift motor.

Precor Error 03, Memory, RAM, EEPROM Test Error Probable Cause This error message almost always indicates an upper PCA problem when it is consistently displayed. Failures causing this error message to be displayed are rare. Corrective Action If the error message is consistently displayed when the unit is powered up, the upper PCA should be replaced. It is possible to see this message displayed intermittently due to external causes. If the units A.C. input significantly dips during the power up test sequence the test could fail resulting in this message being displayed. Treadmills operating on non-dedicated A.C. circuits may see this message displayed on an intermittent basis. Precor Error Code 03 E03 EEPROM Test Error
