I have problem with a york eco2 chiller Mo#YCAS0118EB46YGADBT The chiller has been running fine for yrs and about 2wks ago. Reprogram refrigerant to run is showing up in display. System is set to R-407C and dip switch is set to open position which is for R-407C. But display still says reprogram ref type.
Anyone got some ideas on this?
