Many LG microwave users have reported this problem and expressed frustration and disappointment. Thankfully, there are uncomplicated measures you can adopt to fix the LG microwave door error and restore your microwave to its normal functioning.
I will make sure that I show you how to fix the LG microwave door error in simple and easy steps. By closely adhering to this guide, you can restore your microwave to normal functioning and enjoy your delicious meals again.
What is the LG Microwave Door Error?
The LG microwave door error is an error code on the display when the microwave detects the door is not closed correctly. A faulty door switch, a misaligned door latch, or a damaged door seal can cause this occurrence. The error prevents the microwave from starting or heating your food, which can be annoying and inconvenient.
The door switch is a safety device that ensures that the microwave only operates when the door is closed. The door latch is a mechanism that locks the door in place when it is shut. The door seal is a rubber gasket that prevents microwave radiation from leaking from the oven. If any of these components are defective or damaged, the microwave will not recognize that the door is closed and will display the error code.
Common Causes of LG Microwave Door Error
Several factors can cause the LG microwave door error, but the most common ones are:
- Door latch malfunction: The door latch is the mechanism that locks the door when it is closed and releases it when it is opened. If the door latch is broken, loose, or misaligned, it may not be able to engage or disengage properly, causing the microwave to think that the door is open when it is closed or vice versa.
- Door spring issues: The door spring plays a crucial role in ensuring that the door moves seamlessly when opening or closing. If the door spring is damaged, worn out, or detached, it may affect the movement and position of the door, resulting in a door error.
- Door switches failure: The door switches are the sensors that detect whether the door is closed or open. They are located inside the microwave cavity, behind the door latch. If the door switches are faulty, dirty, or miswired, they may not be able to send the correct signal to the control board, leading to a door error.
- Wrong control board: The control board is the main circuit board that controls the functions and settings of the microwave. If the control board is defective, damaged, or corrupted, it may not be able to receive or process the information from the door switches, resulting in a door error.
How to Fix the LG Microwave Door Error
There are several possible ways to fix the LG microwave door error, depending on the cause of the problem. Below you will see the complete seps on fixing the LG microwave door error.
Inspect the internal parts.
First, check the door latch, spring, and switch for visible damage or wear. To do this, you will need to unplug the microwave and remove the screws that secure the outer casing. Then, carefully lift off the casing and locate the internal parts. Look for any signs of cracks, breaks, bends, or corrosion. If you find any, you must replace the damaged part with a new one. You can order the replacement parts online or from a local appliance store.
Reset the microwave
Sometimes, the door error can be caused by a simple glitch in the control panel. To clear the glitch, you can try resetting the microwave. To do this, plug the microwave back in and hold the Stop/Clear button for about 10 seconds. This will reset the microwave and clear any error codes. Then, try to use the microwave as usual and see if the door error is gone.
Check the control board.
If the door error persists, it may be due to a faulty control board. Unplug the microwave again to check the control board and remove the casing. Then, locate the control board, usually behind the display panel. Look for any signs of burns, shorts, or loose wires. If you find any, you must replace the control board with a new one. You can order the replacement control board online or from a local appliance store.
Check the Door Switch
First, check the door switch to see if it works correctly. To do this, you will need to:
- Disconnect the microwave from its power supply and allow a brief interlude of several minutes to elapse.
- Open the microwave door and locate the door switch. It is usually a tiny plastic or metal piece attached to the microwave frame near the door hinge.
- Press the door switch with your finger and see if it clicks. If it does not connect, the switch is faulty and needs to be replaced.
- If the switch clicks, use a multimeter to test its continuity. To test the switch, adjust the multimeter to the lowest resistance setting, then carefully place the probes onto the terminals. The switch works correctly if the multimeter shows zero or meager resistance. If the multimeter shows infinite or very high resistance, the switch is broken and needs to be replaced.
To replace the door switch, you will need to:
- Remove the screws that hold the control panel in place and lift it off.
- Disconnect the wires that connect the switch to the control board.
- To remove the switch from its current position, it is necessary to loosen and extract the screws that hold it in place on the frame.
- Install the new switch in the same position and secure it with the screws.
- Reconnect the wires to the control board and put the control panel back in place.
Adjust the Door Latch
A misaligned door latch is another possible cause of the LG microwave door error. The door latch may become loose or bent over time, causing the door not to close correctly. To fix this, you will need to:
- Disconnect the microwave from its power source and allow a few moments to elapse.
- Open the microwave door and inspect the door latch. It is usually a metal hook that protrudes from the door and fits into a slot in the frame.
- If the door latch is loose, tighten the screws that hold it in place.
- If the door latch is bent, gently straighten it with pliers.
- Close the door and see if the error code disappears.
Replace the Door Seal
A damaged door seal is the last possible cause of the LG microwave door error. The door seal may wear out or tear over time, allowing the microwave radiation to escape and triggering the error code. To replace the door seal, you will need to:
- Disconnect the microwave from its power supply and allow a brief interval for it to reset.
- Open the microwave door and peel off the old door seal. It is usually a rubber gasket that runs along the edge of the door.
- Clean the door surface with a damp cloth and let it dry.
- Apply a thin adhesive layer to the new door seal and press it firmly onto the edge.
- Cut any excess seal with a sharp knife and smooth out wrinkles or bubbles.
- Close the door and see if the error code disappears.
Preventive Maintenance for LG Microwaves
To avoid the LG microwave door error from happening again, you should perform regular maintenance on your microwave. This will help to keep your microwave in good condition and extend its lifespan. Here are some tips on how to properly clean and maintain your microwave:
Clean the microwave regularly.
It is advisable to clean the microwave at least once a week to eliminate any food spills, grease, or dirt that may accumulate inside the cavity. You will need a damp, mild detergent and dry cloth. First, unplug the microwave and wipe the inside of the microwave with a wet cloth and the detergent. Then, wipe the inside of the microwave with a dry cloth to remove any moisture. Wipe the door and the door seal with damp, detergent, and dry cloth. This will prevent food particles or debris from interfering with the door latch or switches.
Avoid slamming the door.
You should avoid slamming the microwave door, which may damage the door latch, spring, or switch. Instead, gently close the door and ensure it is fully latched before using the microwave. You should also avoid opening the door while the microwave runs, which may cause a power surge or a short circuit.
Use the microwave properly.
It is using the microwave according to the manufacturer’s instructions and recommendations. It would be best not to use the microwave for purposes other than cooking or reheating food, such as drying clothes, sterilizing items, or heating liquids. You should also not use the microwave with metal utensils, foil, or containers, as this may potentially ignite fires, and cause damage to the microwave. You should also not use the microwave if damaged, broken, or malfunctioning, as this may pose a safety hazard.
