Electrolux Epic 2500 suction stopped - Electrolux Vacuums

It could be the switch or could be the suction motor. Also, there is a thermostat on the motor that will shut it off if you don't have the air flowing to keep it cool. If that is the case, the motor will re-start after it cools down.
If the motor dosen't start, the cheepest way to start is to buy a new switch and install yourself. Just make sure where the wires go. The single terminal is to the front and the two terminals to the rear. The black wire goes to the front single terminal, the red wire goes to the far back terminal and the blue wire goes to the front back terminal. The suction motor should come on first and then the power nozzel. If not in that sequence,reverse the blue and red wires.
If that fails, take it to the Aerus/Electrolux shop.
