I think its oval shape made it easier than if it had been around one. The start capacitor is used during the startup phase of the motor and gets disconnected from the circuit when the motor reaches its predetermined speed, which is 75% of the maximum speed of the motor. For most motors, as long as the actual value is is within the 10% mark of the rated value, you're in good shape. In unusual circumstances, a run capacitor could be used as a start capacitor, but the values available for them are much lower than the values usually available for dedicated start capacitors. (The + -5 after the MFD is how much it the capacitor tolerance is rated to go up or down.). I have two systems and when one run capacitor failed five years ago I replaced them in both units with no problems since. A capacitor does not emit any odor, other than performing an electrical diagnosis the only indicators that it might be bad is swelling, extreme wear (rust/corrosion/etc.). The U. S.

There was a red and purple wire attached to one terminal, a red wire to another terminal, and an orange wire attached to the third. Guess its time to order a new fan motor. Just a minute ago I went out and the fan was slowly spinning backwards. :ywf 4D-500 Any idea? I suppose the new one could be bad, which I will check, but Im wondering if it could also be the wiring. Compresser stays running but fan motor stops. Now, Im confused, did I really have a bad capacitor?. Motor start capacitor lets the motor turn on and off rapidly, and helps the motor run more efficiently. Only problem is Im not sure which wire I should connect to the small capacitor and which one to use to supply voltage to the compressor capacitor? Terminations are usually " push on terminals with 2-4 terminals per connection post. Not sure, but maybe when the compressor starts the fan reverses too. Capacitors are not very expensive like the other components of an air conditioner. A run capacitor will have a marked voltage rating that should not be exceeded. For most modern run capacitor designs, this will open the circuit, disconnecting the internal spiral membrane as a protective measure to prevent the capacitor from popping.
