Hey there! Are you facing the frustrating issue of your Frigidaire Microwave FFMV1846VSA’s light bulb not working? Don’t worry; you’ve come to the right place! In this blog post, we’ll dive into the possible reasons behind this problem and explore some simple solutions to get that light shining again. So, let’s roll up our sleeves and shed some light on the matter!

1. Understanding the Light Bulb Function in a Microwave

Before we jump into troubleshooting, it’s important to understand the function of the light bulb in your Frigidaire Microwave FFMV1846VSA. The light bulb serves two primary purposes: illuminating the microwave’s interior and providing visual feedback during cooking.

2. Checking the Power Source

The first step in troubleshooting a light bulb issue is to ensure that the microwave is receiving power. Start by checking if the microwave is plugged in securely and if the power outlet is functioning properly. You can try plugging another appliance into the same outlet to verify if it’s working.

3. Examining the Light Bulb

Now, let’s move on to the light bulb itself. Begin by turning off and unplugging the microwave for safety. Carefully remove the bulb cover located inside the microwave cavity. Take a close look at the bulb to see if it’s burnt out or damaged. If you notice any signs of damage, it’s time to replace the bulb.

4. Replacing the Light Bulb

To replace the light bulb, you’ll need to find a compatible replacement. Refer to your microwave’s user manual or contact Frigidaire customer support for the correct bulb type and wattage. Once you have the new bulb, follow the manufacturer’s instructions to install it securely.

5. Checking the Light Bulb Socket

If replacing the bulb doesn’t solve the issue, the problem may lie with the light bulb socket. Inspect the socket for any signs of damage, such as loose connections or corrosion. If you notice any issues, it’s advisable to replace the socket. Again, refer to the user manual or contact customer support for guidance.

6. Examining the Control Board

If the light bulb and socket are in good condition, the next potential culprit could be the control board. The control board regulates various functions of the microwave, including the light bulb. A malfunctioning control board can prevent the light from turning on. In such cases, it’s recommended to seek professional assistance for repair or replacement.

7. Checking the Door Switch

Another component that can affect the light bulb’s functionality is the door switch. The door switch ensures that the microwave only operates when the door is securely closed. If the switch is faulty or misaligned, it may prevent the light from turning on. Inspect the door switch and consult the user manual or customer support for guidance on adjusting or replacing it.

8. Resetting the Microwave

Sometimes, a simple reset can fix minor issues. Try resetting your Frigidaire Microwave FFMV1846VSA by unplugging it from the power source for a few minutes. Then, plug it back in and check if the light bulb starts working. This method can help resolve temporary glitches and restore normal functionality.

9. Seeking Professional Help

If you’ve tried all the above steps and the light bulb still refuses to cooperate, it may be time to call in the professionals. Frigidaire’s customer support or a certified technician can provide expert guidance and assistance in diagnosing and resolving the issue.


Congratulations! You’ve made it through the troubleshooting journey to fix the light bulb issue in your Frigidaire Microwave FFMV1846VSA.
