periodically and you may not notice it unless your fan runs slow or the compressor sometimes doesn’t come on right away. With the fan running slow it still cools, just not as efficiently. The capacitors sending random voltage or low voltage can eventually short the motor, the control board and sometimes damage the compressor.

I know this because it happened to me. Resistance in the fan was way out of spec due to a capacitor that wasn’t always working correctly. The capacitance was supposed to be 40V for start and 5V for Run but the start side was all over the place. No swelling or leaking like they is usually do.

The fan kicking on eventually shorted out the relay on the control board. It happened early spring and I noticed it was taking 4hrs to cool a couple of degrees.

I tested and confirmed all components and they all measured bad. Replaced all three one at a time just be sure.
