Can you hear the motor turn or hum when you activate the switch? If not, locate the motor and with someone holding the switch, use a circuit tester to check for power. If no power when holding switch, put the switch off the wall, and check for power there. There is likely a fuse in the circuit. It SHOULD be between the switch and the power supply, but no guarantee. You may actually want to start by checking that fuse.
