COMPRESSORS HAVE AN INTERNAL T-STAT TO PROTECT THE WINDINGS ... SOME THING IS CAUSING YOUR COMPRESSOR TO RUN "HOT" THIS WILL KICK "IN & OUT" THE COMPRESSOR DURING COLLING OPERATION AND HEAT MODE (IF IT IS A HEAT-PUMP). 1ST THING TO EASILY CHECK IS THE CONDENSOR "OUT-SIDE" COIL. (CLEN BOTH WHILE YOU ARE AT IT). THESE FANS PULL THE AIR IN AND A BLOW OUT THE COIL .... ALL THE DIRT WILL BE ON THE INSIDE. 2ND THING IS THE FAN ITSEL OVER HEATING AN TURNING "OFF" ON ITS OWN "BUILT-IN POTECTION T-STAT". THIS WILL GIVE YOU THE IRRATIC OPERATION YOU ARE DESCRIBEING. I TEND TO THINK IT IS YOUR FAN MOTOR ... EASY TEST. TURN "OFF" EVERYTHING BUT THE FAN. SET IT FOR MANUAL "RUN ALL THE TIME" POSITION. THE FAN SHOULD NOT KICK OFF !!! IF IT DOES YOU FOUND THE PROBLEM. IF IT DOES TURN OFF IT CAN BE A WEAK CAPACITOR. UNITS VARY ON WETHER THE CAPACITOR IS FOR COMPRESSOR/FAN OR HAS A SEPERATE CAPACITOR FOR EACH. CAPACITORS ARE NOT EXPENSIVE. HOPE THAT CAN NARROW YOUR PROBLEM DOWN

The cooling fan is a must!
Otherwise, the magnetron will be ruined, and that drives up the repair cost.

Capacitor, dirty condencer coil causing the motor amps to run too high. But most likely worn bearing on blade side of motor causing it to pull to one side causing it to over heat and shut down. Sleve bearings should have no side play.

There could be a cold solder joint somewhere in the audio signal path. Finding this will be a difficult task since you will need a schematic and layout. One thing you can try to do to find the problem though is get a can of freeze spray from an electronics supplier. When cold solder joints heat up they expand and break contact. When hit with freeze spray they contract again thus making contact.

TOYO mini split air conditioner made in Japan is very very good quality and it can runs for 20 years without any problem. You didn't hire a best ac technician to install your TOYO unit. The tubing connection between indoor unit and outdoor unit is not the right torque and refrigerant leak. Your TOYO unit runs out of refrigerant. You need fix the leak and fully charge the system. You will solve the problem.
