PCB board fault codes and solutions
When a PCB board failure occurs, the timer digital tubes on the display
panel always display the fault code, and all the burners that are being
heated stop heating, and automatically return to the shutdown state after 1
minute. For the burners that have been worked, t he corresponding d igital
tube continues to display the high temperature warning sign " ". When the
fault code appears, please refer to the scheme in the following table to
solve.
