How to indicate that the remote controls work fine

How to indicate that your remote control works fine?

It simply points the infra red transmitter of the remote control on any digital camera lens ( ON position), press any button of the remote control. It blinks on the screen of the camera, now you can see which button that doesn't work (no blinking)

I have a videocon vitaair AC . The remote control function is not functioning. The AC is not receiving any signals from the remote. Remote control has new batteries and display working.kindly help.


you can check if the remote is transmitting by looking at the end of the remote where the little bulb is that you point at the air con unit through a smartphone camera and press each button, if the light flashes the remote infra red transmitter is sending. your mobole camera can pick up light in the part of the spectrum your eyes cannot and displays as a flash. it will at least let you know if the problem is the remote transmitter or the units receiver

Why isn't my remote controlling my wwk-05crn1-b17 5000 ac unit? I have looked in both remote and A/C operating manuals.


Check the transmit LED is working on the remote by pointing it into the lens of a digital camera and pressing the power button. The camera will pick up the infra red flash if it is working. If it is OK, the receiver board may be shot, which is relatively common for air conditioners.

cant get the controller for my fujitsu auy18asd to work with the unit theres no beeping or nothing


An easy way to check the remote is to use a digital camera. Turn the camera on and point the remote at the lens. Look at the camera screen and press a button on the remote. If it is working, you should see the transmitter flash a purple/blue colour. This is not visible with the naked eye so you have to use a digital camera to see it. A phone camera works fine. If you see the transmitter flashing, the remote is probably ok and the receiver board or controller board in the head unit is faulty.

Remote won't work but can manually operate


you do the camera tricks just to ensure if the infra red sensor of the remote is working. get a digital camera turn it on,then get the remote controller. press any button at the remote controller pointing to the digital camera, if you see a light at the display of the camera then the infra red sensor is good but if no light either the sensor is worn out or the circuit was defective.
