What To Know
- If the multimeter reads an infinite resistance when the door is closed, the door switch is likely faulty and needs to be replaced.
- Fixing an LG microwave that is not heating can be a challenging task, but it is possible to resolve the issue yourself with the right troubleshooting steps.
- The cost of replacing the magnetron can vary depending on the model of the microwave and the labor charges.
If your LG microwave has suddenly stopped heating, it can be a frustrating experience. However, before you call for professional help, there are several troubleshooting steps you can take to try to resolve the issue yourself. This guide will provide you with a step-by-step approach on how to fix an LG microwave that is not heating.
Troubleshooting Steps
1. Check the Power Source
- Ensure that the microwave is plugged into a working electrical outlet.
- Inspect the power cord for any damage or fraying.
- If necessary, replace the power cord with a new one.
2. Reset the Microwave
- Unplug the microwave from the power outlet and wait for 30 seconds.
- Plug the microwave back into the outlet and power it on.
- Check if the microwave is heating properly now.
3. Clean the Microwave
- Food particles and grease buildup can interfere with the microwave’s operation.
- Use a damp cloth to clean the interior and exterior of the microwave, including the door seal.
- Wipe down the magnetron (the metal tube at the back of the microwave) with a soft cloth.
4. Check the Magnetron
- The magnetron is responsible for generating the microwaves that heat the food.
- If the magnetron is damaged or malfunctioning, the microwave will not heat.
- To check the magnetron, use a multimeter to measure its continuity. If the multimeter reads an infinite resistance, the magnetron is likely faulty and needs to be replaced.
5. Inspect the Door Switch
- The door switch is a safety mechanism that prevents the microwave from operating when the door is open.
- If the door switch is faulty, the microwave will not heat.
- To check the door switch, use a multimeter to measure its continuity. If the multimeter reads an infinite resistance when the door is closed, the door switch is likely faulty and needs to be replaced.
6. Check the Capacitor
- The capacitor is a component that stores electrical energy and releases it to power the magnetron.
- If the capacitor is faulty, the microwave will not heat.
- To check the capacitor, use a multimeter to measure its capacitance. If the multimeter reads a significantly lower capacitance than the specified value, the capacitor is likely faulty and needs to be replaced.
7. Contact LG Support
- If none of the troubleshooting steps above resolve the issue, it is recommended to contact LG Support.
- They can provide further assistance and arrange for a technician to repair the microwave if necessary.
Troubleshooting Tips
- Always unplug the microwave from the power outlet before performing any troubleshooting or repairs.
- Refer to the LG microwave user manual for specific instructions and safety precautions.
- If you are not comfortable performing any of the troubleshooting steps, it is best to contact a qualified appliance repair technician.
