Samsung microwave light not working. Whenever we have a microwave bulb not working, there are several things we can do to troubleshoot the issue before calling in a professional repair technician.
The good news is that newer microwaves come with switches and buttons on the front panel that allows you to attempt some solutions without needing to open up the microwave device and take a look at what might be wrong.
Even though your microwave may still be under warranty, it’s nice to know which issues can be resolved with your own home maintenance skills versus those that may require more attention from a specialist.
Samsung microwave light not working
Here we will discuss some common issues and solutions.
Replace Main Control Board
Test the light socket and bulb first. If they are working, then it’s likely a faulty wiring or control board problem. If the bulb/socket combination doesn’t work, you have to check if the wiring is loose or frayed, corroded, etc.
Check for loose screws in the bulb cover. If everything seems to be fine here too, then it most probably is in the control panel which is causing a weak current flow by itself. To get rid of this problem we will have to replace the whole control panel assembly.
Light Socket issue
Remove the burnt-out light bulb from the socket, dispose of it properly and replace it with a new one. If that didn’t fix the problem, test the socket for continuity with a multimeter. If the socket shows no sign of continuity, replace the socket.
Faulty Light Bulb
Things fail when the whole is greater than the sum of its parts. The problem with having a light bulb control your house’s electrical system is that it might get overwhelmed, and if everything the bed all at the same time then you got trouble.
A bulb has failed
Bulbs naturally cease to function after some time. When a bulb ceases to function, you have several options: you can replace the bulb yourself or the worst-case scenario involves taking your appliance to the manufacturer or a trusted repairman.
Almost all microwave ovens have bulbs built-in for illuminating their interiors. Removing the bulbs typically requires unscrewing it from its port, but different microwaves require fitting specific types and brands of replacement bulbs so be sure to check before beginning any work.
There is a problem with the door latch system
A microwave door latch is fitted with several small switches, and if any of these components are faulty, the light will not come on. There’s a chance that the fault could be inside the microwave itself, but you can check all of the switches yourself.
If both switches are connected, then the fault could be inside the microwave itself. Each switch should have continuity in one way or another.
There is a problem with the main circuit board
A microwave’s main circuit board handles all of its functions, such as temperature regulation and motorized power. If the microwave is still under warranty, you can get the manufacturer to replace it without any issues.
However, if it has been over six months since purchase, then you may have to take on this task yourself.
All that you need to do is to read carefully through the safety instructions given above and then proceed with caution so as not to damage anything or hurt yourself in the process.
