Bosch Range vent hood fan or light not working
When a Bosch range vent hood fan or light is not working, start with the thermal fuse, the most likely cause listed for this problem. A blown thermal fuse can interrupt power to the fan motor or light, so test it for continuity with a multimeter and replace it if continuity is absent. If the fuse is good, check the fan switch, followed by the on-off switch. A defective switch may prevent voltage from reaching the fan motor or light. Other possible causes include a failed micro switch, switch kit, or rocker switch. Test each switch for continuity and replace any part that fails the test. Before servicing the Bosch range vent hood, disconnect electrical power and use care around wiring. The fan motor, blower wheel, light bulb, wire connector, or control components may also need inspection if the switches and thermal fuse test good. Enter your Bosch 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.
