    Would the room sensor prevent the fan from running if the "Mode" is set to "Fan" on the remote?

A high pitched noise from the fan unit, means a bearing issue from the motor. You must replace the fan motor to get rid of the noise.

How do I get the fault codes up on a Panasonic split air conditioning system CUE24FKR


14.2.2 To Make a Diagnosis1 Timer LED starts to blink and the unit automatically stops the operation.
2 Press the CHECK button on the remote control continuously for 5 seconds.
3 "- -" will be displayed on the remote control display.
Note: Display only for "- -" (No signal transmission, no receiving sound and no Power LED blinking)
4 Press the TIMER ? or ? button on the remote control. The code "H00" (no abnormality) will be displayed
and signal will be transmit to the main unit.
5 Each press of the button (? or ?) will increase error code
number and transmit error code signal to the main unit.
6 When the latest abnormality code on the main unit and
code transmitted from the remote control are matched,
Power LED will light up for 30 seconds and a "beep" sound
(continuously for 4 seconds) will be heard. If no codes are
matched, Power LED will light up for 0.5 seconds and no
sound will be heard.
7 The breakdown diagnosis mode will be canceled unless
pressing the CHECK button continuously for 5 seconds or
operating the unit for 30 seconds.
8 The LED will be off if the unit is turned off or the RESET
button on the main unit is pressed.

The memory data of error code is erased when the power supply is cut off, or press the Auto Switch until "beep" sound heard following by pressing the "CHECK" button at remote controller.
Although operation forced to stop when abnormality detected, emergency operation is possible for certain errors (refer to Error Codes Table) by using remote controller or Auto Switch at indoor unit. However, the remote controller signal receiving sound is changed from one "beep" to four "beep" sounds.

Mitsubishi timer light 6 times blinking


Indoor unit indicator
RUN lamp = 6 time flash
TIMER lamp = Comes on
Outdoor unit indicator (LED5) = Stays off
Description of trouble = Indoor fan motor error (2)
Cause = Defective fan motor, Connector poor connection
Conditions of flashing = When air conditioner is operating and indoor fan motor is turned ON, indoor fan motor speed of 400 rpm or under continued for more than 30 seconds. (Air conditioner stops.)

Initially fan in indoor unit was surging,cutting in and out,now has stopped completely and red/green flash twice followed by red flashing 4 times


The flashing indicates a fault code. Not knowing what make / model you have makes it impossible to determine the exact fault. If the indoor fan was running erratically, it may just be a fan capacitor on the indoor unit. Some units have a separate capacitor, some have the capacitor mounted on the main indoor control board. Check and see if the fan starts if you give it a flick to start it spinning when you turn the air con on. If it runs and the error flash does not appear, then you will know its a fan capacitor.

F6 error code on Frigidaire split unit ac, model FSC12CM6J/FSE12CM6J. Solution says to check fuse? Where is this located?


It seems like the indoor fan is not running. Quite a few split systems have a fuse on the indoor board. It will require stripping off the outer cover of the indoor unit and removal of the electronic box cover. The indoor board is in there. The fuse may be replaceable or it may be a type that is soldered on which makes it virtually non replaceable. ( A new indoor board will be required) Make sure all power is turned off or disconnected before you do anything. Another possibility is the fan motor start capacitor has failed. Try this first before stripping the unit. When the unit is turned on and the outdoor unit has started, give the indoor fan barrel a flick with your finger to start it spinning, if it keeps spinning and the error doesn't appear, it would indicate that the fan motor start capacitor has failed. The capacitors on indoor units are normally small black square boxes with 2 terminals on it. These capacitors are mounted inside or close to where the indoor electronic box is. Again, make sure all power is disconnected or turned off at the meter box before you do any disassembly.

I addred coolant to the AC unit a few weeks ago and it has been running fine until last night. I went to check the pressure and make sure the line was not frozen this morning since the indoor air climbed...


Hi,
It is just coincidental that the fan motor died now...
Replace the condenser fan motor and you will be good again...

I have a Fujitsu inverter split system,(ASTA18LCC) which the power was removed for a while. Now when you start it up on any mode the red operation light is on briefely, then the green timer light flashers...


To work out what the error code ispress the orange start/stop button on the remote controller so unit operationis stopped.
Then press and hold "energy save" and "zone control" buttonsimultaneously for at least five seconds, the error code will be along thelines of En:nn where the "En:" is the error code and the":nn" indicates the indoor unit address if there are multiple indoorunits connected to the one controller. If the upper vertical bar on the capitalE is missing so it looks maybe like a 2 or something don't worry for somereasons they just do that
Some common error codes are:
E0 Communication error between indoor unit and wired remote control, check ifthere is 12VDC between terminal 1 + 3 at remote control and 8-9VDC pulsatingbetween terminal 2 + 3. If DC volts out of Indoor pcb is below about 11.6VDC itwill cause this error, the problem is normally dry capacitors in the 12 VDCpower supply section. This model has two power supply sections on indoor pcb.
E1 Communication error between indoor unit and outdoor unit,
EF Discharge temperature abnormal
Is it helpful?

My fan stop working the blades are not turning and all it does it's a noise but it don't spin


Is this your indoor fan (this isn't a window unit is it)? Turn the power off and make sure the fan spins freely by hand. If it does then check the capacitor for the fan. If it doesn't spin freely then you may need a new fan motor.

Fujitsu split level


Check for errors like blinking indoor light if present. Reset the error by disconnecting power supply from the unit for 10 sec. and "on" the unit. If the error persist, some parts of the unit may be defective and need to replace. Like room air thermistor, coil thermistor in the indoor side or the relay board. Some safety device in the outdoor may give in, some outdoor parts may be defective. You need a qualified technician for the this problem.
