On a service call on sunday, i needed to replace a 45/7.5 uf capacitor and did not have one. I took a chance and put in a 45/5 and fan and compressor are working just fine. Does that mean the previous cap was a replacement that was too high or why would the fan operate on a lower rating capacitor?
Is there a downside to having a lower rating capacitor?

Fan motor m ay be running a slightly higher amp draw now, or not really spinning as fast as it should.
