if the fan switch is in the Run position and not the auto position you are getting cool are when the heat element is not on. this is kind of like a way to circulate the air. look for an auto setting it then should only come on when needed. Keep in mind it is normal for the fan to start blowing before the heating element is warmed up, this prevents it from over heating, or coming on when the fan is not working
your fan most likely is wired for low speed for heat which is common. this should be determined when furnace is set up properly. motors that aren't modulating motors and are multispeed motors typically have low medium and high taps that come off the motor and go to the corresponding relay on the board. low and medium speeds are used for heat and high and medium speeds are used for cooling. but only one speed for heat and one speed for cooling many times medium never gets used. im not familiar with klimaire is this a mini split system and not a regular air handler. cause speed control should be adjustable from the remote. if its a split but if not reaching desired speed due to a malfunction in the units could cause it to run low speed just to maintain the temperature exiting the indoor unit.
The system blows cold air when turned to on position but also makes that sound between cycles
NOTE THE ON / AUTO SWITCH BETWEEN GREEN,FAN AND YELLOW ,COOL TERMINALS ON THE THERMOSTAT, THE FAN SWITCH NORMALLY CLOSED GOES TO LOW, HEAT SPEED, WHILE THE NORMALLY OPEN GOES TO THE HIGH SPEED, COLING SPEED. BY TURNING FAN ON NOTHING BUT FAN SHOULD RUN..
SWITCHING THE BREAKER TO OFF PRECLUDES THE UNIT FROM DOING ANYTHING !
WHAT CAN IT DO WITH NO POWER! I switch the breaker to the off position when not using the a/c in order to keep this cycle from occurring. A
low medium high speed of fan iscontroled by selector switch on the thermostat or recheck the thermostat if ok check control wirnig from thermostat to the fan relay on control borad and from relay to the motor.
I f it is fan that has more then one speed if you run it all the time,it may
not be on high sample : low fan speed runs all the time
med fan speed for heat
high fan speed is usually for air conditioning so if everything is good then it maybe the relay.
