Take the front cover off and see if the drive belt is on the motor. Try running it to see if the motor turns. This could be a motor or controller board problem.

It sounds like you have a membrane issue. There are a number of different T9450 models and they all have slightly different consoles. You'll need your serial number to help pinpoint the parts you need. Your best bet is to go through the manufacturer (johnsonfit.com) and have them help you get the correct membrane and overlay.

The power up test sequence has detected a key in the operated condition. The power up test
sequence is performed every time the unit is turned on (powered up). This test is performed
because a permanently stuck key will inhibit the correct operation of the unit.
Possible Causes
1. A key on the display housing is permanently stuck in the operated condition.
2. One of the upper PCA's keypad interface chips has failed.
3. Liquid (perhaps perspiration) is present on the surface of a touch sensitive display.
Possible Remedies
1. Remove the keypad connector cable from the upper PCA. Restart the power up sequence, if
the ERROR 5 is no longer present, the keypad is the cause. The keypad is typically part of
the display housing. Replace the display housing to correct the problem.
2. Remove the keypad connector cable from the upper PCA. Restart the power up sequence, if
the ERROR 5 is still present, the upper PCA is the cause. Replace the upper PCA to correct
this problem. Most upper PCA's are provided without software. Therefore, the software (chip)
must be removed from the upper PCA being replaced and re-installed on the replacement
upper PCA.
3. Wipe the surface of the touch sensitive display clean of all liquid. Restart the power up
sequence, if the ERROR 5 is no longer present, the liquid was the cause.

Precor Error Code 26 Error Code: 26 Manufacturer: Precor
Model: All Models
Error Description: Error 26, Motor Pulse Width Incorrect - Observation of the speed sensor signal and verification the signal from the speed sensor is appropriate for the requested speed. If an incorrect or erratic speed sensor signal is detected the error appears. Possible Reason:
  1. The line of sight between the speed sensor and the speed sensor target is obstructed.
  2. Incorrect gap between the speed sensor and the speed sensor target.
  3. Incorrect adjustment of the speed sensor potentiometer (when equipped).
  4. Damaged speed sensor target.
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. 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".
  3. 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.
  4. Inspect the speed sensor target for any scratches or tears that could cause incorrect readings. Replace the speed sensor target if
Precor Error Code 26

The buttons on this unit are on an overlay. Basically, the buttons are a big sticker that goes on the console. I would start by checking the connection between the overlay and the console board. If the connections in good, then try a new overlay. If that does not work then the console board is bad.

The Steps for Newer Style Console Calibration:

  1. Locate the calibration area on the rear or underside of the console (a hole, near the console's center, that goes through to the electronics board. (This hole should not have a screw in it.)

  2. Insert a pencil (eraser end), into the hole and feel around for the cal button (will click when pressed).

  3. Press the button 2 times (with the pencil eraser). The first click should show CL11 in the console, the second click should show CL21.

  4. If the process was done correctly, and CL21 appears in the console, you are in "calibration mode." The next few steps consists of pressing buttons on the console and observing settings. This will not require any other tools.

  5. Press ENTER. CL22 should display in the TIME window and (??) in the SPEED window.

  6. Press ENTER. CL23 should display in the TIME window and (??) in the SPEED window.

  7. Press ENTER. CL24 should display in the TIME window and (??) in the SPEED window.

  8. Press ENTER. CL25 should display in the TIME window and (??) in the SPEED window.

  9. Press ENTER. CL26 should display in the TIME window. You should then see the letter "E."

  10. Press ENTER. You should see "SS" or "55" in the console.

  11. Push the STOP/START button. For safety, at this point, you should step off, or be off, the treadmill.

  12. Push the ENTER button. The walking belt should start to move, accelerate to maximum speed, then stop on its own.

  13. When the belt stops, the incline should self test by raising to its highest incline position, then lowering back down to its lowest position.

  14. Once the incline test is complete, push the POWER button 2 times. The unit should shut off and the console should go completely blank. If this happens, the treadmill is done calibrating and is ready for use.

  15. If the letter "F" appears in the SPEED or INCLINE window when the power button is pressed 2 times, the treadmill is indicating a failure somewhere either in the SPEED or INCLINE (depending on the window the "F" appeared in). Troubleshooting the failure would be the next step.

It appears that your elevation system is where the fault lies. This could be as simple as recalibrating the lift mechanism, or possibly correcting faulty wiring from the lower controller to the lift motor. Be sure to check the condition of the lift motor as well as the wires entering the lift motor. Sometimes the wires will pull away from the plastic connector causing a lift motor error
