Question about Heating & Cooling
Hi - my Toyo minisplit will flash error code - 4x in 8 seconds. At this time the fan will slow down and the unit will sometimes drop water from where air exits. After a few minutes - the unit will return to normal, only to start this again in 10? minutes. Seems to cool well.
Check your air filter and indoor coil fins if clean. If it is dirty it need to be clean. But if it is clean you need a qualified technician for this problem.
