Daikin RXE35B fan and pcb trouble

[pan2]

Hi, my first post. Like a lot of others, I'm appalled at the back up from Daikin - won't fix boards - replace at insane prices. Enough of my rant :) have an inverter unit RXE35BVM in Australia. flashing green LED in fan unit led me to outdoor inspection. on closer inspection I found that the fan bracket had completely rusted out and was just floating around, possibly causing the fan to become jammed against something. The big PCB sitting on top of the unit had what looked like the result of a scorch mark on the plastic cover just above a component - Q1 (c3751) I think is a mosfet. I have no idea how to access one of these despite hours of googling till I arrived at this amazing site. I've removed the pcb and the fan. It's still spinning freely but I haven't as yet tried to power it to see if it's going. Spinning freely is not necessarily meaning that it's good I guess. Can anyone give me some advice on what to do next? Oh, another rant - why couldn't they simply make the fan bracket from stainless? So many Australian live on the coast as I do and are subject to salt air. Emailed Daikin about this, and you guess right - no reply :(

the best idea for those who live on the coast is to have their units treated with blygold, this will stop the corrosion.
If all of the units were made of stainless the production costs would go up, the system should be maintained and parts can be replaced where necessary if corrosion is present.
