If your LG microwave is not turning on, it can be a frustrating experience, especially when you rely on it for quick meals. A microwave that won’t power on may be caused by several issues, from simple power problems to more complex internal faults. In this guide, we’ll explain the common reasons why your microwave isn’t turning on and how to fix it. We’ll also introduce Reliant Solutions, the best LG service center for appliance repairs.
Common Reasons Your LG Microwave Is Not Turning On
1. Power Supply Problems
One of the first things to check when your LG microwave won’t turn on is the power supply. Ensure the microwave is properly plugged into the outlet and that the outlet is functional. You can check if the outlet is working by plugging in another device, like a lamp or phone charger.
2. Blown Fuse
A blown fuse is a common cause of a LG microwave not turning on. The fuse protects the microwave’s internal components from electrical surges. If the fuse blows, the microwave will not function. Replacing the blown fuse is a simple fix, but it requires disassembling the microwave, so it’s recommended to get professional help.
3. Defective Door Switch
Microwaves have door switches that ensure the appliance doesn’t turn on when the door is open. If the door switch is faulty, the microwave may not start. Inspect the door switch and the latch to ensure they are working properly. A broken switch may need replacement.
4.Tripped Circuit Breaker
Sometimes, a tripped circuit breaker can cause the microwave to lose power. Check your home’s electrical panel to see if the breaker has been tripped. If so, reset the breaker and check if the microwave powers on.
5. Faulty Control Board
The control board acts as the brain of the microwave, regulating its functions. If the control board is damaged or malfunctioning, the microwave may not turn on. In this case, the control board might need to be replaced by a professional technician.
How to Fix an LG Microwave Not Turning On
1. Check the Power Supply
Make sure the microwave is properly plugged into a working outlet. If the outlet isn’t functional, try another one. If the microwave still doesn’t turn on, move on to the next step.
2. Inspect the Fuse
If the microwave is completely unresponsive, a blown fuse might be the issue. Check the fuse, and if it’s blown, replace it with a new one. Be cautious, as handling fuses requires opening the microwave.
3. Test the Door Switch
Check that the door closes securely and that the door switch is functioning. If the switch is broken, it can prevent the microwave from starting. Replacing the door switch can solve the issue.
4. Reset the Circuit Breaker
If the circuit breaker has tripped, simply reset it. Ensure that the breaker is fully in the “on” position and try turning on the microwave again.
5. Consult a Professional Technician
If your microwave still won’t turn on after these steps, it may be time to call a professional technician. Reliant Solutions specializes in LG microwave repairs and can diagnose and fix the problem efficiently.
