ERROR ATTITUDE: Snapped

REASONS:
1.Tension strength is extremely too high
2.Foreign part coming into the transmission system or other parts of this system error or not in the right position SOLUTIONS:
1.Correct the tensile strength, check the pulley parallel then change the belt
2.Remove the foreign parts and make sure the position of each part in this system is right then change the belt

ERROR ATTITUDE: Cracks
REASONS:
1.Belt tension too low or too high
2.Belt working with the too high temperature 3.Belt lifetime exceeded
SOLUTIONS:
1.Change the belt and correct the tensile strength 2.Check whether the fan function well and tight ancillary com-ponents then change the belt
3.Change a new belt
