Here is what a clogged up fan looks like.
What happened in this case is someone was visiting, staying in the guest house, they adjusted the system to extreme settings. We've had our mini-split system for 6 years now. We've had it happen 3 times in those years where a visitor has caused this to happen, despite our warnings.That's a nasty looking fan!
Seems like you have a humidity scale or growth occurring on the fan - are these running all the time to condition the space, or "as needed when it gets to warm/humid?
The units would have to be moved to drill the concrete. I should have done this before they were installed.Our Mitsubishi are Hyper Heat 2 9K and 1 12K and drain onto the ground below, a crushed stone border around the house - it does make an ice cake 2" high but no issue. We don't have the heated pan version and never had a problem with the tray freezing or blocking.
What about drilling thru the concrete walk like a 4" opening below each unit and adding crushed stone instead of a heated line?
Oh that's a good reason - ours are 2'+ off the ground to stay out of the snow.
Set the temperature and take the remote before guests arrive. Problem solved.What happened in this case is someone was visiting, staying in the guest house, they adjusted the system to extreme settings. We've had our mini-split system for 6 years now.

Two ways I've seen it happen. Someone sets the AC to the lowest temp setting possible. The unit never shuts off, and the coils and fan never get a chance to dry/drain during cooling cycles as normal. Second condition is they set the fan to high and turn the temp up and leave.
