If your Arietta range vent hood fan or light is not working, a blown thermal fuse is the most likely cause. Test the thermal fuse with a multimeter for continuity, and replace it if the circuit is open. If the fuse is good, check the fan switch, which may prevent voltage from reaching the fan motor. A defective on-off switch can also stop power from reaching the fan or light. Next, test the micro switch, switch kit, and rocker switch for continuity, replacing any switch that fails the test. These parts can cause an Arietta range vent hood fan not working, light not working, or both symptoms at the same time. Disconnect power before testing or replacing electrical components, and use the wiring diagram for your model when needed. Enter your Arietta range vent hood model number to find the exact replacement thermal fuse, fan switch, on-off switch, micro switch, switch kit, or rocker switch for your specific appliance. With the correct part and a few basic electrical tests, you can often restore your range vent hood without replacing the entire unit.

A defective fan switch may not allow voltage to reach the fan motor to run it. To determine if the switch is defective, use a multimeter to test the switch for continuity. If the switch does not have continuity, replace it.
A defective on-off switch may not allow voltage to reach a light or fan motor to turn the light or motor on. To determine if the switch is defective, use a multimeter to test the switch for continuity. If the switch does not have continuity, replace it.
To determine if the micro switch is defective, use a multimeter to test the switch for continuity. If the micro switch does not have continuity, replace it.
To determine if the switch kit is defective, use a multimeter to test the switch for continuity. If the switch does not have continuity, replace the switch kit.
To determine if the rocker switch is defective, use a multimeter to test the switch for continuity. If the rocker switch does not have continuity, replace it.
