Hi Guys
Got a daikin A/C split with a indoor wall mounted unit (R410A). installed by another company.Never worked i got called in showing a fault U4. past experiance of a U4 code on the daikin means outdoor PCB. Checked outoor unit and LED A was not lighting which also indicates outoor pcb. Bought a new pcb and came with a capacitor which had to be added to the pcb. Changed the pcb but the fuse blew straight away. Discoverd mix up in wiring and sorted out wiring. then coming up code PJ as soon as i switched it on.I fitted the capacitor wire which came with the unit and now it is coming up with the code E0 as soon as i switch it on rang up daikin tech and they said to check all the safety devices to see if they all are sending 240v to the devices and 240v coming back. all fine except only 24v being sent and coming back to the low pressure device.the pcb is fine what do i do now??? PLEASE HELP
