Question about Fujitsu 18C1 Air Conditioner

1 Answer

Wall Hung A/C unit remote control # AR-DL10 batteries died last. Replaced remote batteries with 4 new duracell batteries. Unit came back on but running to warm. I tried to figure out the programming of the remote but can not get it to even swing the louver. This cools a computer server room that needs to cool down soon. Looked for remote mannual online but could not find one. Please help me get this remotre working. At present I tried to set it to 64 degrees. That usually kept the room at 70. I keep pushing buttons and the remote will change but the wall hung unit will not respond to its commands. Jack (Facitities Director for Paulsboro School District in NJ)

    I have exactly the same problem! Still searching for a solution. Cheers.

    Having changed the batteries in remote, hit ACL and reset the remote's time, it is unable to communicate with the air con unit at all. Other remotes can still activate the air con but not this one.

    Does anyone have a link to manual?

I just got onto a technician who solved the problem for me. What he had me do was:-

  1. Pull dowwn the slider and use a pen to press the ACL button.
    That didn't fix it so...
  2. Take off the slider (the way you would to change the batteries). There is an ABCD slider switch and mine was set to "C". I moved it back to "A" and now it works! I am not sure how it got to "C" though ???
The other thing is I had been messing around with the "Manual/Auto" button under the grill on the wall unit. It was set so that the A/C was off. I'm not sure if that is significant.

Hope that helps.

Cheers,

Unionaire wall mounted a/c/heater only works manually.Remote control no longer works even with new batteries.Should I order a new remote control or is the transmission problem from the wall unit?


check the remote operation with your cell phone
put new batteries in the remote , turn on the cell phone to camera and point the remote at the lens of the phone
press any button/s on the remote and a white dot will appear on the cell phone screen
that is the infrared of the remote transmitting
that would then mean that the receiver in the wall unit is not working

I have a model AR-DL10 remote. One of the batteries corroded , installed new ones and now the unit will not respond. What should I do?


Pull the new batteries and clean the terminals. If cleaning don't work the corrosion may have damaged the remote. Use a PC of sand paper, or scratch the surface that the batteries touch.

Why doesn't remote control communicate with Fischer heat pump mini split system


It sounds like the batteries leaked and oxidized the terminals. If you cannot get them clean enough then I would suggest getting a new reomote from the manafacturer.

Remote unit slides open but cant find battery cover-model AR-DL10


When sliding the bottom part of the remote down, you have to lift it slightly (I did this with a letter opener - very carefully) to pry the door up from two stops that normally prevent the dorr from sliding down too far. If you look carefully, you can see what I mean.

Replace remote control unit model ar-fb2


If your remote control have display but cannot transmit signal to the unit. Confirm first if the remote is really the problem, using your camera or cellphone camera as your eyes point the remote transmitter to your camera and "on" the remote. You should see light emits in your remote control, if no emitted light then the remote control is defective. But if there is a light the defect is in the unit receiver.

Check also if there is a reset or rst button in your remote control and reset it and try.

Check also if there are error codes in the unit, reset the unit by disconnecting the power supply in the unit for 10 sec. and "on" again and try.

The unit can be operate without remote control, use the manual button located in the unit.

If the remote control have no display replacement of remote is recommended.

Blower fan will only work in low speed


Sometimes after you replace the batteries in the remote, there is a communication disruption between the remote and the wall hung evaporator. With fresh batteries installed, take a paper clip and press in on the "reset" hole located on the remote. Yes you will have to reset the clock but it may help your situation. Then you will need to turn off both the inside unit as well as the outside unit. You must first turn back on the outside unit then the inside unit. If it continues as you have described, it could be a relay on the Main PC board and the board will need to be replaced. If all other functions and modes work, you will probably not have to replace the Receiver PC Board.
