My Whirlpool 6th sense split type air conditioner doesn't cool.Everything lights up as always and the red indicator inside shows the compressor should be running.Outside the fan is running.When I stand outside by the unit every 10 seconds or so I hear a relay click followed by a 5 second humming sound then the relay kicks back out and this will continue every 10-15 seconds.Something(the compressor?)is trying to engage but all I get is the humming.This is the same hum I've heard on other electrical devices when a motor tried to turn but was frozen and couldn't.I was an auto mechanic and the humming meant something wasn't turning and the high resistance caused the relay that turned it on to kick back out to avoid overheating or a fire hazard.I can take the covers off the unit very easily but what am I looking for? The unit itself is only a few years old so it's not worn out. Help please!!
