Hi. Hoping someone can help. I have a BH fitness pioneer classic model G6442C. It switches on fine but belt wont start turning and after few seconds “E1” error pops up. I have opened the box and tested and no power gets sent to the motor when you press start. “LED2” flashes once belt wont start. Any ideas anyone?

'1.If the belt moves, but stops after a short time and
thedisplay shows "LS", run calibration. (on next page)
2.If you press start and the belt never moves, then
the display shows LS, contact service.

Does the walking belt move for a brief moment, then immediately stop, followed by the E1 code? Or is there no belt movement at all when start is pressed?

If you push start and the belt does not move then it seems like the is a problem. This problem may be the LCB.

Dear Sir:
This is probably a 1) faulty speed sensor or 2)the speed sensor is not plugged in properly. Its also possibly a 3) faulty motor control board or lower board 4) Main motor faulty. . The error codes will differ between makes and models but could be e1.You must test

see my personal TIPS for diagnose and troubleshooting.

See if you can run the software calibration for diagnose and trouble.

sincerely. God bless you.

Lets eliminate the motor first, unplug unit remove motor shroud fin the 2 leads from motor to lower board. Connect a 18v DC battery to the leads this start the motor to move at approx. 1 mph if it does motor is good,if not you may worn motor brushes worst case open connection in the motor.
Now if the motor is good then reconnection the leads and plug in unit the lower board should have some LEDs lit up. Now find the LED that says PWM start unit if that light should start to flicker then the upper board and wire harness are work properly. Turn off the treadmill then turn it on and with a multi meter insert the leads into the connectors that go to the motor, then put the meter on 200v DC then start the treadmill you should get a reading 5 to 10v DC if you get 0v DC then the board will need replacing

Did you find a solution for this issue? I have a similar situation

Your problem might be that the sensor magnet has fallen off. Here's an illustrated guide that should make fixing it easy: http://fixmytreadmill.blogspot.com/2010/10/how-to-fix-treadmill-e1-error.html

Good luck.
