I got a call from one of my customers and he said the ac is not working. Its a wall mounted comfort star CMO24B (condenser) and CMI12B (evap.) split unit. Condenser is not running, I check the board and its flashing and i transfer it over to the chart and it says its the " indoor middle temperature sensor malfunction". So i call the supply house and he tells me they dont go by that anymore. The switched the name to evaporator sensor or indoor climate sensor. Has anyone had a similar problem. I contacted the manufacturer and they said its the indoor climate sensor. i switched it out on both of the evaporators and still nothing. Does anyone have any input on this
