Low Refrigerant Detection (Flashing A/C Indicator)
LOW REFRIGERANT DETECTIONThe controller monitors the state of the low-pressure cycling switch, if the compressor has been activated, and measures the duration of the compressor "On" time.
The minimum compressor "On" time limit will be 1.5 seconds. Once this limit (less than 1.5 seconds) has been exceeded for 10 consecutive cycles, the compressor will be turned off and remain off until the servicing has been performed and the battery disconnected to reset the memory.
The A/C indicator will flash for a period of two minutes and then turn "Off" when the low charge condition has been detected. It will also flash at every ignition cycle for two minutes until the servicing has been performed and the battery disconnected to reset the memory.
