Solution
1. Check and re-connect the
signal wire
2. Change a new signal wire
3. Turn off electricity supply and
restart machine
4. Change anew controller
1. Check the wire connection
2. Change a new wire
1. Check if the power is in the
normal range
2. Change driver board or main
board
1. Program
error,
electricity supply and restart
after 3 minutes
2. Change driver board
3.
Check
sequence connection
1. Check if the power is in the
normal range
2. Change driver board
1. Check the compressor
2. Check the waterway system
3. Check if the power is in the
a
normal range
4. Check if the correct PFC
inductor is used
1. Change a driver board
2. Check if the motor speed is
too low or fan motor damaged,
change another one
3. Change another fan blade
turn
off
compressor
