One more quirky thing about RV A/C units, at least the ones I've had. You can control the temperature, and the fan speed. Mine has Hi, Lo, and Au, for high, low, and auto. In high and low, the fan stays on all of the time, even when the compressor is off. In auto, it chooses high or low, and turns off the fan when the compressor is not on. Also, when you change it from low or high to the other, or if it is in auto and it decides to change the fan speed, the fan will stop for a couple of seconds, but the compressor will continue to run. Pretty strange.
OK,
1. The OP does not have your type AC unit
2. The reason the fan stops when changing fan speeds is simple. The Fan motor has 3 separate wires. One each for each fan speed. So, it must kill power for each fan speed and then power up the other fan speed wire. It cannot do that at the same time. So, there is a small 1 to 2 seconds delay between speed changes. Doug
