One of my ductless a/c units is not blowing cold

Select hot mode except cool

check controls or solenoid valve on inside unit

Hire a tech it will be cheaper and safer. You may have a capacitor that is bad and not starting the compressor.

That's an inverter series motors... the outdoor fan motor is on an ambient controller to maintain pressures when cold outside in air conditioning mode, but not in heat...only defrost when needed. Check the settings on the outdoor board for defrost timing

Sounds like it could be low on freon I believe these units have about 1.5 pounds of freon in them and are critical in not undercharging or overcharging them if it is a freon 410 ac unit the pressures should be about 135 and both lines cold if is low on freon a service tec will need to be called to try to repair the leak if possiable

I just experienced this problem myself. What helped me was cleaning out the lint trap. My guess is that the until sucks in air through there, then conditions it. Blows the cold air out the top, and hot air out the tube. When it can't suck a decent amount of air in, the condenser can only condense so much of that limited amount of air. When it runs out, the unit just runs the fan until enough air has been condensed.

My lint trap was filthy, hadnt Bern cleaned in years. Soon as I popped it off, the unit started belching out cold air nonstop. Clean your lint traps! Don't make my mistake!

Ice means coolant is low

I, have a LS120cp lg ductless.The only way I,can get the unit to run is by pressing the test button on outdoor board.

Check your thermostat and mode selector setting, thermostat setting should be set at warmer and mode selector setting should be at low heat or hight this is applicable for manual unit.
If it is a remote control just set the remote to heat mode.
