there may be two faults of thermocouple and solid state at the same time. The thermocouple wire is broken or the wiring is falsely connected, resulting in the decrease of temperature display. At the same time, the solid-state breakdown short circuit, the internal normally open contact cannot be disconnected, and it has been in the normally closed state, resulting in the continuous heating of temperature

if the direct temperature rise is not controlled, the solid-state relay is broken down

the temperature controller has a resistance to adjust the compensation near the input end. Adjust it and try.
