I have mpc2003 machine that is having sc-144 error and front door open sign is on. I have replaced SIO, SBU,IPU, and bcu but the issue has not yet been resolve. Any idea? Thanks

Why have you not tried the harness for the 144.

Door open indication could be a bad door sensor. Try using Input test table to trouble shoot.

Both problems could be related. Like jams, some SC codes will not clear if the door is not being properly detected as being opened then closed

hi, thanks for this information as I was able to solve the problem today already. I have replaced the PSU only as no stock for controller but luckily machine was able to start up normally and now is working fine already. Appreciate all your replies guys. Thank you.
