Hi wonder if anyone has had a 4225 fault , I had this fault and found fan board blown ,fan motor faulty and fan cables rubbed through . I replaced them all and unit ran sweet for 4 days then unit faulted again on 4225 fault . Unit trys to run , no fans or compressors come on then unit clicks off , it does this about 6 times and then comes up with 4225 .Fan board has two leds lights , no 2 is lit .I have checked compressors and fans plus fuses and all ok .
thanks for any help
did you replace the fan cable?- as you know you can unplug it under the fan but where the cable drops down and goes under the enclosure where the comp is housed it gets hot and cooks inside the black outer sleeve
hi yeah new cable fitted so all that side should not be a problem really
<In the case of 4225>
Check the followings
1Check the voltage of CN52C
on the main board
→ Refer to (3).
2Check whether 52C1 works
normally → Refer to (4)
Or check 52C1-connecting piping.
3Check for the diode stack
→ Refer to (5)
4Check for the wiring and the
connectors of the CNVDC on
the FAN board.
Replace FAN board when no
fault is found for the above 1~4.
hi thanks for your help , I've checked cn52c and diode stack and all seem ok , it points to the fan board but it a brand new only 4 days old , if it has indeed gone then either it is faulty or something else has taken it out. its a weird fault really with all new parts fitted . back to the drawing board for me tomorrow , I have other units I could swap parts but don't always like doing that really.
