Try with this method which happened last week experience. Replace new batteries. And also remove dc wire to indoor unit display sensor. And after 3 minutes fix it again. And now start with remote. Mostly it will. If not, you have to replace receiving sensor in PCB or replace complete PCB. Please write back about the result. Thanks.

Hi,

Most probably if the remote works on the other units then the receiver on your problem unit is busted. You have to call an authorized service repair shopr to replace the board.

I hope it helps.

Use your cellphone or any digital camera as your eyes by pointing the camera to the remote control transmitter. Light should emits on the remote control receiver. If no lights means defective remote control. But if lights emits means that either the receiver board or the main board is defective.

Try also the rst or reset button if present. Reset and try the remote.

check your remote control using your camera or cellphone camera as your eyes. Point the remote control transmitter to your camera and "on", light should emit in your remote control transmitter (means good remote). Check for reset or rst button in your remote control and push it to reset and test it in your unit. If wont work means either the receiver board or mean board is defective.You need a qualified tech. for this problem. For the mean time you can use manual button to operate the unit.

Replace receiver board or if you have a spare unit try to transfer the receiver board to the defective one and test the remote to confirm the unit problem.

replace your receiver board it may be defective.

- check if the battery is still good
- check if the receiver of the unit is clean and no obstruction.
- Some of remote control have a reset switch, every time you change it with battery you have to reset it.
- Some of remote control have A and B selector at board and remote control, check this if they set at the same frequency.
- To check if the remote control still working you have to test your remote control to other unit with same model as yours. If its not working then replace your remote control. But if its working then you have to replace your receiver board.
- Some remote control have to be reconfigure so you have to read your manual.

- Check if the battery is ok.
- Some remote control have reset button, you can find it at the front or back at the compartment of the battery push the rst button with pin or ballpen to reset it and try.
- Some remote control have selector switch in both remote control and at the board inside the unit. Try to transfer the switch button from A to B and also at the board inside the unit and reset the remote control and try.Or need to reconfigure the remote control to select the frequency.
- Try your remote control to other unit with same brand as yours to confirm if your remote control is really need a replacement. If it works then your receiver board in the unit is need a replacement. Or if wont work then you have to buy a new remote control. But if you have no budget then try to switch on the unit using emergency button to operate the unit.

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.
