My Mom's Tili AC unit (TM111VR) is not turning off --- I turn off the power but the fan continues to run (and the compressor) when the display is off. I have to unplug the unit for it to stop.
I opened it up and checked the board for fishy caps etc -- all looked good. The relay on the board looked good as well. Inside the unit there are two black run type (I think) capacitors - both 4 connector CBB61 -- different ratings --- from reading it would appear that maybe these are somehow faulty. So I'm thinking I need to source them -- but I'm unsure of exactly what the fault is or could be, and how to eliminate the relay on the board from the issue to these specifically.
From my reading it would appear that these run type capacitors act almost like relays -- that they can fail in such a way as to be always on or always off. Here's some photos:

Anyone ever deal with this kind of thing? Many Thanks
