Get Error 3 message When running calibration procedure the motor kicks in as soon as Incline check begins and continues until Incline check is finished and continues for several minuted and then shuts down. After this the Erro 3 message appears and Treadmill will not start. I replaced the control board and the same condition continues as with the old board. The new board Is the Exact copy of the Original. Can you help me. An Instruction Manual might help me to find the problem. Thanks: Virgil e-mail virgilpauline@;yahoo.com
