Hi All
Hope someone can help.
I have been called out to a VRF with a P22 fault. I ordered up and fitted today the upgraded IPUD board. I did not replace the fan as the winding are ok, aprox 3.1 ohm.
The P22 fault has cleared but the fan wont run and thus goes out on HP.
I have had the same faults on 2 other units over the last 12 months but I have changed the IPUD board and the fan at the same time and hey presto were away.
I suspect the board (the new one has failed) but can someone give me the head up just in case im missing something obvious.
I have been in touch with Toshiba Tech support UK and they say i should change the fan, and the board my be faulty. But the resistance of the fan is within there quoted tolerence.
Any help appreciated
