A microwave as you all know is one kitchen appliance which we use everyday and infact several times a day. The appliance is used not just to heat food and liquids but also cook, bake and grill etc. Microwaves come in various sizes and models but the basic parts and features remain the same. One thing that every microwave in the world has in common is a light bulb which lights up when you open the door. But what if you face the problem of microwave light bulb not working? Well the following are some of the possible causes and some solutions for such a situation.
1. Light bulb may be burned out
One of the most common causes for microwave light bulb not working is that the bulb itself may be burned out. To check whether this is the problem and to solve it, you need to first unplug the microwave and then shut off the power to the microwave at the breaker point itself. Check your microwave to locate the vent and remove its panel by unscrewing the screws. Find the box containing the halogen light and remove its cover. Unscrew the bulb and remove it and install a new one.
