Hi, I've had this issue on a Daikin minisplit that I installed less then one year ago. The unit works flawless in cooling mode, but in heating mode it doesn't work as it should.
After switching from cooling to heating the 4 way valve changes position, and compressor builds up pressure to about 450psi, the the indoor fan should kick in within 1 to 4 minutes, it ramps up 1 sec and then start turning so slow you can't hear it anymore (fan works well in cooling and ventilation mode). I suppose the indoor Coil 20K ntc Thermistor must feel the heat to keep spinning, I will change it tomorrow, but if that's not the problem (I don't think they malfunction a lot) I have no more clue, has someone ever had a similar problem and what was the solution ?
