Daikin RZQSG71L3V1B No power to indoor

[eire1]

Hey folks, just wondering if anyone has come across anything similar on a Daikin RZQSG71L3V1B? I’ve an indoor unit that has no power, it’s fed off the outdoor which does have power. I assume it’s either a blown fuse or a faulty PCB? I should add that I had the green LED flashing but no lights on any of H1P to 7. Going back tomorrow with a tall ladder to properly reach and investigate.

there are two fuses in the out door unit

Check the High Float switch on the condensate pump. Some installers put the live or neutral through this switch to stop the unit if the pump fails.

Thanks guys. Found F1 on the outdoor blown. Mini Lime was fine, all indoor connections OK. I found a loose neutral for a pump for outdoor drip trays. I can only assume that this races and blew it. Ran fine for 60 mins once repaired.
