Cleaned filters, changed batteries in remote, prayed a bit, and it worked - no idea which activity was the remedy!

SOURCE: Gold Star mini split heat pump 24,000

On a heat pump the difference from heat to cool is the reversing valve.
In cooling or heating the Y1 terminal will always be energized, this is the contactor.
Depending on brand the reversing valve will either be energized in Heat or Cool. At the outdoor unit check to see if the reversing valve is getting 24 volts in cool, if not check to see if it is getting 24 volts in heating. The easiest way to check if the reversing valve is shifting, is to feel the big copper tube, (it is not the suction line on a heat pump) this is a refrigerant vapor line. It will be cold in cooling and hot in heating.
Check your thermostat installation instructions and heat pump installation instructions to determine the proper terminal designations for your heat pump and thermostat. There are some brands out there that use the B terminal as common to the 24 volt circuit, so you have to check the wiring and make sure this is not common.
If it is energized in Cool then the Y1 and O terminal will be energized. You will have 24 volts from common usually the C terminal to Y1 and O.
If it’s energized in Heat then the Y1 and B terminal should be energized. You will have 24 volts from common usually the C terminal to Y1 and B.
If you get heat when you’re calling for cooling or vice versa then switch the wire between the B and O terminals.

Please cancel your timer setting by reset the power. And also remove battery from your remote and reset it. Now start your unit.

What does the snowflake mean on a Honeywell thermostat in cooling mode. Also had the problem in the heating mode.


The snowflake means it's cooling. If the outdoor unit is not running then the problem is likely outside.

Fujitsu asta18lcc has a constantly fast flashing green light and the red light flashes slower 5 times with a small gap between each 5 flashes. Unit wont work at all apart from lights.


The red light (operation) flashing 5 times can be one of four things depending on the green light (timer) but the green light should flash at the same rate as the red light, not faster - either 2,3,5 or 6 times. Anything other than these is abnormal and you will need a tech to diagnose.
Could be a faulty controller board or compressor.

That is an alert code. Most heaters require forced air venting, and some use a vacuum switch to test for that airflow before igniting gas flame.

The cooling light is always on, and it takes about 90 minutes to dry a load.


In normal operation as the dryer is drying the "drying" light flashes and the "cooling" light is on steady until the 5 minute cooldown at which time the "drying" light stays on steady and the "cooling" light flashes. click on this lg link
