30gx probleme
I am facing problem with Carrier chiller model 30gx227a0224nee . I've just change the CPM board of compressor A2. although the LED red flashlight turn on, the green one dosn't work and the compressor A2 dosn't run. It would be helpful if you send me the address of DIP swich on the CPM board and tell me why LED green flashlight dosn't work.
Thanks a lot

Re: 30gx probleme
Is the board set for the correct compressor?
Green LED shows a communication error, check fault codes.
Do you have a manual for the unit?

Check dip switch settings on old CPM board then set new CPM the same. Then CPM will communicate

match your dip switch settings from the old board to the new board.
