You should be fully familiar with the electrical components of each function, location, connection and other devices around the relationship if without electrical equipment assembly diagram, please demolished, while sketching, and mark the mark.

Second, we must first check the aluminum and pvc doors and windows equipment, with no obvious cracks and defects, a good understanding of its maintenance history, life, etc., and then check the machine.Before the demolition should be excluded from the surrounding fault factors, identified as the machine ]after the failure to disassemble.

Third, in the determination of mechanical parts without trouble, and then check the electrical. Check the circuit failure, you should use the detection equipment to find the fault location, to confirm the contactless failure, and then targeted to see the relationship between the operation of the line , So as not to misjudge.
