I am getting an error on the console of my Proform XP Treadmill that reads: checksum: fail...what does this mean and how can I fix this?

First try a full power reset and also look for the motor trip reset button.

Ask the manufacturer

Verify the wire harness to the console has continuity with a multimeter.

Very common for the harness to be damaged if disassembled and reassembled during a move.

Otherwise you would need to source a wiring diagram from mfg to see what the readings should be at the console connection.

If that all checks out then it most likely is the upper control board.

Just because the lower board is getting power doesn’t indicate it is functioning

Follow this steps in order to fix it.
However if the problem persist, time to REPLACE the complete Controller board motor. Some IGTBs is faulty.
Blessing.

Have the same problem with a Nordic Track Eliptical. Sorry, I have no solution. What solved yours?

Press the Stop and the Speed Up keys down while inserting the safety key.
Press the Stop key one time. The Time window should read EP:2P. Some newer models may also say FP, Pass, or the like. This means that it passes the EPROM test.
Press either incline key and the incline will calibrate automatically.
After completing calibration of incline, press the Stop key and then remove the safety key.

Errors 00 through Error 04 check upper PCA memory locations, RAM memory locations and EEPROM checksum during the power up test sequence. If a fault is found during the power up test sequence, the appropriate error code will be displayed.
These errors messages almost always indicate an upper console problem when they are consistently displayed. Failures causing these error messages to be displayed are rare.
If the error message is consistently displayed when the unit is powered up, the upper console should be replaced.
