Question about Mitsubishi MSH09TW Air Conditioner
I changed the battery to the remote and the high speed of the blower stayed the same... I did unplug the low voltage wiring to the board and the fan started blowing in high and after 5 seconds it turned off.. help please!!!
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.
