If your Gree Air Conditioner displays a temp sensor/outlet pipe of evaporator temp sensor malfunction, it will be displayed, and an alarm will sound. If the malfunction is automatically resolved, the compressor will resume operation and the malfunction code will disappear. Alternatively, you can select malfunction resetting or manually de-energize the unit to clear the malfunction signal.
