How to Fix Your LG Microwave Fan Not Working Quickly

Check the Power Supply and Settings

The first thing to do is check if your microwave is getting power. Sometimes, the fan won’t work because the microwave is not plugged in properly. Make sure the plug is in tight and the socket works. You can test it by plugging in another device, like a lamp, to see if the socket gives power.

Next, check the microwave settings. Some models have a separate fan button or setting. If it is off, the fan will not run. Also, see if the microwave is in a special mode, like defrost or cooking mode. These modes may limit fan operation. Changing to normal mode can solve the issue quickly.

If the microwave still doesn’t work, the circuit breaker may have tripped. Check your home’s breaker box and reset the switch if needed. Sometimes, a small surge or overload can stop power to the microwave. Once everything is checked, try the fan again.

• Make sure the microwave is plugged in
• Check the fan settings on the microwave
• Try normal cooking mode
• Reset the circuit breaker if needed

Inspect the Fan and Vent for Blockages

Sometimes the fan doesn’t work because the vent is blocked. Open the microwave and check the back and top vents carefully. Look for dust, grease, or small pieces of food. Even small debris can stop airflow and make the fan noisy or completely stop. Cleaning the vent can make a huge difference.

Use a soft cloth or a small brush to clean the vent area. You can also use a vacuum with a small attachment to remove dust and crumbs. Be gentle because microwave parts are delicate. Also, make sure the vent cover is not broken or stuck in place.

Another thing to check is the fan blades. Turn them by hand (with the microwave unplugged) to see if they spin freely. If they are stuck or feel stiff, the fan motor may be the problem. Cleaning or replacing the blades can help the fan work smoothly again.

• Check vents for dust and food
• Use a cloth or vacuum to clean
• Inspect fan blades for smooth movement
• Ensure vent covers are not stuck

Test the Fan Motor and Connections

If the fan still does not work, the motor may be faulty. First, unplug the microwave before touching any parts. Then, find the fan motor. Usually, it is at the top or back of the microwave. Look for loose wires or damaged connections.

Use a multimeter if you have one. Test the motor for continuity. If there is no reading, the motor may be burnt out. Even if you are not an expert, seeing disconnected wires or corrosion can tell you that the fan motor needs repair or replacement.

Sometimes, simply tightening loose wires can fix the problem. Other times, replacing the motor is the only solution. You can order a new motor from LG or an authorized supplier. Make sure to follow the manual when installing it.

• Unplug microwave before testing
• Check wires and connections
• Use multimeter to test motor
• Replace motor if needed

Clean or Replace the Filters

Many LG microwaves have filters that stop grease and dust from reaching the fan. These filters can get very dirty and prevent the fan from working. First, remove the filter according to your microwave’s manual.

Clean metal filters with warm soapy water. Plastic filters may need replacement if very dirty. Some filters can be rinsed and dried, but others must be replaced completely. Keeping filters clean helps the fan move air efficiently.

Check filters every few months to prevent future problems. A clogged filter not only stops the fan but can also cause smoke and smells in your kitchen. Good filter maintenance keeps your microwave working longer and safer.

• Remove filters according to manual
• Wash metal filters with warm soapy water
• Replace very dirty plastic filters
• Check filters regularly

Inspect the Control Board and Buttons

Sometimes the microwave fan works perfectly but the controls fail. This can be due to a problem with the control board or buttons. Start by looking at the control panel for any damage. If buttons feel stuck or don’t respond, the board may be faulty.

A stuck button may send wrong signals to the fan. Press each button to see if it clicks normally. If the fan does not start after pressing the fan button, the board might need service. Some LG microwaves allow simple board replacement, but complex boards may need professional help.

Also, check for visible signs of damage, like burnt marks or corrosion. Moisture and heat can damage electronic components over time. Replacing the control board often restores the fan’s function completely.
