The Outdoor cooling fan (the subject of this article) moves outdoor air across the condensing coil to cool it and assist in condensing the high pressure, high temperature refrigerant gas back into a liquid.It is this process Is there rust on the bottom of the capacitor? My guess is no low speed, but we need to know all circumstances in which that speed is used to assure dropping it is ok. Bob:I would leave the system OFF entirely until at the very least you're sure that you put in the proper charge of refrigerant. The Unit Is Too Small or Has an Old Thermostat.

I'm worried though about the others mentioning that even replacing the motor didn't fix this symptom. Capacitor is brand new. 1. Minor bends can be corrected manually; damaged blades need to be replaced.

You can check the fan setting on your thermostat. Turn The Fan Switch To "Off" And Back To "Auto": If the . Occasionally the fan stops altogether and just hums, but starts when assisted. The movement of outdoor air across the condensing coil transfers heat to outdoor air and allows high pressure/high temperature refrigerant inside the condensing coil to condense from a gas back to a liquid refrigerant. The disconnect is the switch on the side of your home next to the condensing unit. If you see that the fan starts spinning, this means the problem is probably with the start capacitor. I replaced the motor and the capacitor and neither fixed the problem. Secure the Drain Pan. -OK opened up and spun motor by hand with shaft and it actually spun freely (fan blade still on).
