My AirCooler or Fan suddenly stops when my husband, was playing a battery operated plane in the house. Now the Air cooler fan can have a sound , the light is on, but once you turn on for it to move, it will stop by itself. I have tried other switches like Ion, Evaporater, Timer, Speed and OSC with the ON/OFF button. It doesnt work. I have given it a shake, I have put on real ice in the air cooler. It doesnt work.
