This code indicates a fault with the cooling system, in particulary the discharge pipe temperature sensor.

SOURCE: fan noise indoor unit (asu12rlq) fujitsu

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.

Have a 2009 Nissan Quest I can't turn the heat off. Just stays on a high level of blowing out heat .


If you have a fan that has different speed settings (1234, or low med high etc) and the only one that works is high - then the blower resistor pack has failed. If you have a climate control unit (where you just pick a temp you want) then the fan is controlled by the heating system and it sets fan speed. If you have climate control style try lowering the temp to a lower setting (current temp in vehicle) and see if fan slows down. If not then climate control unit or fan resistor bad. If dial type and you get nothing on lower settings (only high works like mentioned above) you need to change blower resistor. It is located under dash near the fan itself. Look for small unit bolted in duct near fan with wire plug going to it.

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

Switch on by pressing ON/OFF. Press mode button to cool position. for cool and keep required temp by clicking

Same procedure for Heat. For heat keep +29 and for cool 25 to 22 degree. Press fan for High, Med,Low. If you keep mode in Auto cool and the fan speed will be low and you can't change fan speed.


Please visit Fujitsu website for further details. Hope my msg is helpful?

Ofm is running at half speed and compressor is not starting


The outdoor fan may operate at two speeds. The hotter the discharge air temp at the outdoor unit, the faster the fan runs. I would check the suction line and liquid line to see if they get cool when you call for cooling.It is very hard to tell if the compressor is operating since they are so quiet.

If this is not the case, you very well could have a bad capacitor,

Fujutsu mini-split 'discharge termperature abnormal' error code


This unit is what is called a Heat-Pump.It has a reversing valve in the condensing unit outside which switches you're system from cooling to heating via this valve.It has a ball bearing inside this that opens a port, and slides to close off another port to reverse the flow of freon from one season to the other.If your code indicates discharge supply air temp. abnormal, you are having a problem of some kind in your out door unit.Even though its new, I have seen these ductless split systems fail within a month. I'm am not saying that you have a lemon, just pointing out they do have problems with main board failures, Freon leaks at line connections because they are not brazed like systems with ducts. But, being this new, you should have this unit still under warranty!! For me to trouble shoot this online would be a long task, I would have to be on site. Call the Contractor now and get them out to make repairs right away. Compressor is normally a year warranty unless you get the 4 year Extention.Failures happen like this on all units, not just yours. It could be many small things that would cause a low discharge air temp. Get them back out!
Sincerely,

F61 error code


Sorry to hear about your error code F61

This code refers to a High Limit Temp. condition.
This is most likely caused by the cooling fan.
If the Fan has stopped running or not running at full speed, you will recv. this error message and the temp. reaches high-end limit.
Please check the cooling fan, any possible air flow restrictions and correct running RPM.

Hope this information has helped you.
Readers, please rate your technicians information.
Thanks,
