Changing a microwave light is an easy task and should not take long to complete. However, safety should always be a primary concern when working with electrical items.

You should also inspect your microwave light for signs of wear and tear to ensure it neither overheats nor operates inefficiently. Test the lightbulb with a voltage tester to be sure all connections are functioning properly before installing it. When replacing, use caution and make sure not to touch the bulb directly as it can get hot enough to burn your skin, damage clothing or discolor objects that it comes in contact with.

Additionally, always wear eye protection when replacing high-intensity bulbs as they have been known to shatter unexpectedly. Following these simple instructions will ensure a safe repair experience.

Identifying the Type of Bulb

Before you attempt to replace a microwave bulb, you must first identify the type of bulb used in the light fixture. All microwaves will usually feature either an Incandescent or Halogen bulb, however some units can be more specialized and may require you to do more research. Generally, light bulbs are rated by watts so if possible, you should try to find this information on your light fixture before attempting to replace the bulb.

Once you have identified the wattage and type of light bulb, look for one that matches these requirements at your local hardware store or online.

Preparing the Microwave for Bulb Replacement

Before you begin to replace the light bulb in your microwave, it’s important to prepare your appliance to make the replacement process easier. Some microwaves can be turned on and off by a switch or lighted button, so if yours does not have one of those, you should unplug it from the wall outlet before beginning. If you have an over-the-range microwave with access from beneath, you may want to remove the unit from its mounting for easier access.

Once you’ve ensured that the appliance is off and unplugged, it’s time to remove the panel covering where your light bulb is located. Depending on your model, this cover may need screws removed or a latch released in order to take it off. Carefully pry open any latches and unscrew any screws while taking note of how they fit back in place when installing them again later on.

Next locate and disconnect the wiring connected to the bulb holder so that whole assembly can be removed together as one piece. Once all connections are disconnected, carefully remove this piece and set it aside until ready for replacement of the bulb itself.

Removing the Old Bulb

When the light in your microwave is not working, one possible solution is to replace the bulb. Before attempting any repairs, make sure to unplug the microwave. This will ensure that no accidental shocks occur during the repair process.

In order to replace the bulb, you must first completely remove it from the microwave. The exact way of doing this varies depending on your microwave model; however, typically, you will need to remove a cover or metal guard in order to gain access to the light fixture from within.

You should also make sure that you are wearing proper work gloves and eye protection during this process as these items are designed to keep you safe while handling electrical components inside an appliance. Removing any panel or covering could involve sharp edges, so be careful when doing so and take your time! Once all of these safety precautions have been taken, carefully unscrew or unclip what’s holding in place the old light bulb and gently lift it out of its bracket.

Installing the New Bulb

To install the new bulb, begin by unplugging the microwave oven and locate the bulb cover. Most covers are held in place with two screws, but some may have clips or a plastic latch keeping it closed. Then, remove the screws or clips and carefully open the cover.

Next, unfasten the socket ring and gently lift out the old bulb while being careful not to touch its glass with your hands.

After taking out the old bulb, examine your new one to make sure that it’s compatible with your oven model and wattage requirements before putting it into place. Then, screw in both sides of the base of your new bulb until it’s securely fastened in place.

Finally, replace any screws or clips on the light cover if necessary before closing and plugging back in your microwave oven.

Testing the New Bulb

When testing the new bulb, make sure the power to the microwave is turned off. Remove the cover of the microwave, which is usually held in place with one or two Phillips screws, and expose the light assembly. Unscrew the old light bulb from its socket and disconnect it from any wiring.

Once disconnected, take it to a hardware store or order a new replacement bulb of exact wattage. Reinstallation should be done exactly opposite to dismantling. Connect the new connector and screw in carefully until snug but not over tightened. Place cover back on unit, replace screw(s) and restore power back to microwave oven before testing.
