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.

SOURCE: Amana Cooling Condensing Unit fan stops spinning after 15 mins

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.

SOURCE: TOYO TA-09CHS aircon problem

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.

Problem is the thermostat.The heat/cool selector switch might not be making try back and fourth from heat/cool to make a good contact.In heat mode make sure the temp is set LOWER than your cooling temp.If it is too cold in the future just RAISE the cooling temp up and not the heat/cool switch.

I have a GrandAire and the aircon works fine; when I turned the heat on, it seems to work fine (warms the house), but the fan in the outside unit is not spinning when the heat is on...is this a problem?...


I think your unit is working in good condition. If you keep in cool mode the out door fan runs to condensate the heat in condenser by taking fresh air from the ambient. And when you keep heat mode, definitely the ambient temp will be too less.I fit takes from their then compressor will get frozting and it couldn't work properly. Depending on pressure increase, the fan will automatically run and stop. Don't worry. Thanks.

You should also check the outside unit to make sure the coil is not clogged with dirt or grass clippings and the fan is working. The reversing valve that switches it from cool to heat could also be a problem. If it isn't shifting it will not switch between heat and cool.

Sounds like your aircon is stuck on heating mode. Or. The outdoor fan speed is affected by ambient temperature, or low refrigerant. In heating mode the indoor fan will come on for a while to sense temperature and will then wait for the outdoor unit to pump up pressure and build up heat.

Yeah, only a qualified or pro aircon tech can replace it. Also the evaporator coil needs to be check for leak. If your unit is still under warranty better call the manufacturer. Anyway, here's how aircon works:

Window air conditioners work on exactly the same principles as a refrigerator or dehumidifier. They have a cooling system that refrigerates the air entering the unit. The moisture in the air condenses on the cold coils and drips into the bottom tray of the air conditioner. The warm air in the room is drawn over the evaporator coil, which collect heat. The heat is conducted into a refrigerant gas. The gas is then circulated to the condensing coils on the back of the unit where it is dissipated to the outside.
