J-30I C5 and D14

The C5 error is definetly a temperature sensor error. I'm reading -85C at room temperature. Should I try to change the sensor?

Thanks,

The sensor was causing the C5 problem. New sensor fixed that right up. Still lost on this D14 error. Is there anything to do besides replace the drive boards in the front?

Thanks,

Just remembered D14 has to do with communication between the cpus. How many aer there? I've changed the main board in head of the centrifuge and the board on teh bottom right behind the front cover. My D14 error persists though.

Thanks,

An "I" series Avanti centrifuge actually has 3 CPU's onboard. The main board, the Fluorescent display has one and the SR control board down on the swing out chassis has the 3rd. Without knowing the status of your replacement boards prior to installing them I really don't know what to tell you because in the 17 years I worked on Avanti J's, I NEVER replaced a VFD board but I suppose that there is always a first time. And yes, a D14 diagnostic is definitely a communications issue so also make sure that all connectors are secure too.
