Troubleshoot PID not coming on or missing numbers on Profitec Pro 600.
My PID Is Missing Numbers or Characters/PID Is Not Coming On
- Inspect the wires in the back of the PID to make sure they are full in the connectors and the connectors are all tight and nothing is unplugged.
- If the display is missing segments or flickering and the connections are all fine, replace the PID.
- If the display is blank, testing for voltage from the board to the PID is necessary to determine if the control board has failed, or the PID has failed.
