Operating amperage too high
Cabinet operation current is too big and will not operate normally. There are two reasons way:
First, the cabinet stops automatically after a few seconds after starting, several minutes later it starts
again and stops automatically again. With in cycles like this and the motor, or starter, and thermal
protection unit will burn up after a long time. The main reason is: the motor coil is shorted at some
parts.
Second, the cabinet operates a certain time after starting, but it will stop automatically before the
temperature reduces before the desired temperature is reached. After several minutes, it will start
again, and the electricity consumption increases bad. The reason is that the insulation around the
motor windings bad.
