This document provides a comprehensive reference for error messages and codes displayed by ADC (American Dryer Corp) commercial dryers. These include heater, blower, thermocouple, safety, and control-related errors with their meanings and troubleshooting advice. 
Diagnostic Features & Advanced Fault Codes
ADC dryers include advanced diagnostics and log systems accessible via the control panel:
- View real-time data on temperatures, motor currents, air pressure, and valve status.
- “Learn Currents” feature calibrates expected heater amperage for fault monitoring.
- Diagnostic error events include codes like E1–E6 (thermocouple, coin errors, etc.) and H1 (heater on with no command).
- Event logs help identify intermittent or historical problems.
Best Practices for Maintenance & Troubleshooting
- Keep thermocouples and airflow paths clean and unobstructed.
- Periodically re-run the 'Learn Currents' process after component changes.
- Confirm proper blower direction after installation or phase swap.
- Maintain 60+ PSI air pressure for S.A.F.E.-enabled dryers with air sensors.
- Use the diagnostics screen to verify inputs, voltages, and event logs.
