We had a terrible night on Saturday when the Aircon didn't respond to the remote control. There is only a switch to turn on or off the unit but nothing to adjust the fan speed and temperature. It was such a warm night...
The remote control works when used on the A/C in my workshop. That means that its the receiving end that is giving the problem.
After church services and dinner on Sunday, I dismantled the A/C unit enough to expose the board. Did the same to the A/C in the workshop to swap the 2 boards.
The IR is the one with 3 pins hear the right of the pic.
The A/C now works as it should. So my guess is correct. Next would be to figure out what's wrong with the board being swapped out. I'm guessing it is just the IR receiver. Anyone know how I can test to confirm this?
All components are through holes. Should be easy to replace the faulty component(s).
The board in its casing.
