Thermocouple Errors E 001 and E 002

Thermocouple Errors E 001 and E 002 in the NCAT Asphalt Furnace indicate issues with the thermocouple sensors in the Chamber and Filter areas, respectively. Both errors suggest the thermocouple is open, failed, or disconnected. Replacing the respective thermocouple usually resolves the issue. If not, verify wiring connections and measure continuity.
