Most common repairs needed to fix a range hood
Light Switch Replacement
When your range hood lights are not working the fan is working, a bad light switch could be causing the failure. The light switch has internal contacts that send electrical current to the light bulb socket to turn on the light when you activate the light switch. If the internal light switch contact is bad, the switch won’t send current to the light socket. You’ll need to replace the light switch if it’s bad. Schedule range hood repair service to have a Sears Home Services technician replace the light switch.
PCB Replacement
If your range hood has electronic controls and the lights are not working even though the fan works, the PCB (printed circuit board) could be defective. This electronic control board operates the exhaust fan and cooktop lights in the range hood. When the PCB won’t send current to the lights, an internal electrical relay could be broken or the internal logic of the control board could be corrupted. Schedule range hood repair service when you suspect that a defective PCB is preventing the cooktop lights from working even though the fan runs properly on your range hood.
Wire Connector Replacement
When your range hood lights are not working even though the fan works, a bad wiring connector could be causing the problem. Wiring connectors inside the range hood allow electrical current to flow from control devices such as switches, user interface controls and electronic control boards to the light socket. When internal wiring connections inside a wiring connector fail, the light can stop working even though the fan continues to work. To find a bad wiring connector, a technician will check for continuity through wiring connections using a multimeter. Schedule range hood repair service when you suspect that a wiring connector has failed.

Things to look out for with a range hood light not working while the fan still works
Diagnosing issues with modern appliances can pose significant challenges for individuals lacking advanced technical knowledge and training. Without employing proper diagnostic techniques, rectifying range hood problems may involve guesswork regarding which parts to replace. In the past decade, appliances have undergone substantial advancements, incorporating intricate electronic components that are increasingly difficult to troubleshoot and diagnose. As a result, do-it-yourself repairs on contemporary appliance models have become progressively difficult. We recommend having a service technician diagnose and repair the range hood when the light is not working even though the fan works.
