First of all, may be the main power fuse, stop grain dryer circuit blocked the operation; this is easy to check out, just cut off the power supply, check circuit is intact, if there is a fuse, replacing the fuse on the line.
    Secondly, it might be because the equipment overload caused by temporary shutdown, this phenomenon is mainly caused by the factors of the material feeding quantity caused by excessive; the main words you need to cut off the power supply of tube material to do some load to remove what equipment.
    Finally, when the grain dryer drying material doped with  equipment beyond that caused downtime; because grain dryer is drying for crop straw type materials with smaller hardness, if accidentally mixed hardness large or larger foreign body, is bound to cause the drying machine can not operate normally, cause stop rice drying machine, this situation only after the power of foreign body check and clean it.
