Fixing your Hotpoint range hood when the lights don't work

A failed electronic control board, bad user interface control, broken light switch, bad light bulb sockets or a wiring failure can prevent the lights from working.

Unplug the range hood and check the wire harness connections between the light sockets and the control board or light switch. Reconnect any loose wires and repair any broken wires. If the wiring is okay, check the electronic control board for burn marks. Replace the control board if you see burn marks because the burn marks indicate a control board failure.

If your range hood uses a user interface control to control the lights, you may need to replace the user interface if it isn't sending signals to the electronic control board when you press user interface buttons. A user interface control is a keypad and display panel that sends signals to the electronic control board through a ribbon wire cable when you press its selection buttons. DIY testing of the user interface control isn't available for most range hood models. If the electronic control board doesn't activate the lights, you'll likely need to replace the electronic control board. If the lights still don't work after replacing the control board, you'll likely need to replace the user interface control.

If your range hood uses a switch to control the lights, unplug the range hood and test the switch for continuity using a multimeter to see if the switch allows current to flow to the lights when you turn the switch on. Replace the switch if you don't measure continuity through the switch when it's turned on.

With new light bulbs installed and the range hood unplugged, check for continuity through the light sockets with new light bulbs installed. Replace the sockets if you don't measure continuity through the sockets with new bulbs installed.

How to replace a light socket in your Hotpoint range hood

• Shut off the house circuit breaker to disconnect electrical power to the range hood.
• Pull the latch tabs to release the air filters and pull both filters out of the range hood. Remove the screws that secure the bottom panel to the range hood frame and pull the bottom panel out of the range hood.
• Unplug the wire harness connectors for the light sockets on the side panel. Pull the front of the side panel inward to release the locking tab and then remove the side panel.
• Grip the bottom of the light socket and turn it to the right to release the locking tabs that hold the light socket in the side panel. Pull the light socket out of the side panel and discard it.
• Install the new light socket and reassemble the range hood. Reset the house circuit breaker to restore power to the range hood.
