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 controller
of
1. Check the wire connection
2. Change wire
1. Check if the power is in the
normal range
2. Change driver board or main
board
1. Program error, turn off
electricity supply and restart
after 3 minutes
2. Change driver board
3. Check compressor 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
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
damaged, change it.
3. Change fan blade
motor
