9.4.2.6 E6(PFC module protection) error diagnosis and solution. (Only for YN036GMFI16M4D)
Error Code
E6
Malfunction decision
conditions
When the voltage signal that PFC sends to main control board
is abnormal, the display LED will show “E6” and AC will turn
off.
Supposed causes
●
Wiring mistake
●
Outdoor PCB faulty
●
Inductance of PFC module faulty
●
PFC module malfunction
Trouble shooting:
PFC module protection
Check whether the
connecting line between
main board and the PFC
module is connected tightly
Yes
Check whether the voltage
range of P-N on IPM
module is normal? DC277-
356V for 18-27KBtu/h;
DC277-410V for 36KBtu/h
No
Check
whether
the
inductance of PFC module
is good? If the inductance is
good, the resistance of the
two ports is 0
Yes
Replace the inductance
No
Connect it tightly, check
normal or not
Replace the outdoor main board
Yes
Yes
No
No
Replace the PFC module
Trouble is solved
