Range vent hood fan or light not working
When a range vent hood fan or light is not working, start with the thermal fuse, the most likely cause when both functions have stopped. Disconnect power, then test the thermal fuse with a multimeter. If it lacks continuity, replace it. If the fuse is good, check the fan switch, which may prevent voltage from reaching the fan motor, followed by the on-off switch, which controls power to the fan and light. A defective micro switch, switch kit, or rocker switch can also interrupt the circuit and cause a range hood fan not to run, a vent hood light not to turn on, or both symptoms at once. Test each switch for continuity and replace any switch that fails. Always shut off electrical power before testing or servicing the hood. Repair Clinic carries replacement thermal fuses, fan switches, on-off switches, micro switches, switch kits, and rocker switches for many range vent hood brands, including Broan, Whirlpool, GE, Frigidaire, and others. Enter your model number to find the exact replacement part for your specific range vent hood and confirm fit before ordering.
