1. Turn on the switch power equipment no response
A. Fuse tube is bad, try a new one
B. Bad switch, change the new switch to try
C. The main control board is bad, use a multimeter to measure the main control board voltage supply is normal, if not normal, the fault in the former power supply circuit failure; if normal, both can be judged to be damaged
2. The display screen shows normal but the motor does not run
A. Motor is bad, use the universal energy meter to measure the resistance value between the winding group to determine
B. Start capacitor is bad: the machine does not turn on, use the hand to apply force to turn. Replace with new one
