green light signal on the inside split a/c unit blinks constantly when the unit is off, which is not normal because I have two other operational units to compare. They are 9,000 BTU whitewestinghouse model WSE095T6MA. When I reset the disconnect box the unit runs real good for approximately 5-10 minutes before shutting off laving the blinking green light. I already repllaced the sensor in the front (tech named pipe sensor). Hopefully someone can assist with an effective solution. Thank you in advance.
