There is a small control board attached under the directional pad. It sounds like it has come loose from the housing. You can get to it one of two ways. You can unscrew all of the back cover screws on the console and then pop the front overlay off using the tabs under the back cover or you can get your fingernails under the edge of the plastic on the front display and pop it off that way. Precor would not approve of doing it that way but it won't hurt the display. The small D-pad pca can be easily snapped back into place. If you get to the pca and its still secured in the D-pad, the control board itself may be bad.

Try to calibrating the lift motor. The following link will take you to a service manual. Check pages 14-15.

It must have been crossing its excess weight limit..

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

1) adjust the reed swithc, clean , and tigh the wire connectors very well
2) run the software calibration for diagnostic and troubleshooting.

Precor Error 29, Excessive AC Input Current Probable Cause 1. The running belt and/or deck are badly worn.
2. Bad lower PCA.
3. 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 lower PCA. Replace lower PCA if necessary.
3. Test unit with a known good drive motor. Replace drive motor if necessary.
