I checked the 2 in the front. I hear them come on. But the wierd thing is that 6 months ago I heard the left fan in the front sound like it was miss aligned. it was making a bizare noise. I was just about to bring it in but it went away. I did have the thermestat chaned recently when the water pump when out. but maybe it is a bad one or not instaled right. How do I check that?
How do I check the fans if they are spinning the rigth amount. Any type of tool or way of testing it
thanks
