Customer Question

I have a 9 year old master cool. It started whistling a high pitch squeal and we can't get rid of it. We've changed out both water pumps, and the motor. It's not the bearing in the cage because when you go from cool to vent it take about 7 seconds for the squeal to stop and it doesn't come back as long as water isn't pumping. What is making this horrible noise. It's intermittent.
