Condenser Fan (cont.)
Temperature can cause some fan speed variation. Fan speed can vary +/- 5%,
depending on the temperature, with higher temperatures causing slightly higher
speeds.
Condenser fan speed is controlled by Pulse Width Modulation (PWM), the same
method used to control fan speeds for the evaporators.
