When started repair was unsure how to remove. First you will need to cut the power to the appliance either by unplugging or on the breaker, which is what I did. Start by removing the switch covers and the bolt on front of the hood and then move on to remove the 2 screws on the underside of the hood. Pay close attention to the wire configuration so that you place them correctly on new switch. Once all this is done and the switch is changed. Turn the power back on and test.
