LG electric ovens are among the most favorite for homeowners and businesses.
Thanks to their industry-standard construction, they allow you to cook or bake at different temperature levels easily. However, the oven might not heat past a specific temperature due to damage and other reasons.
This article looks at some of the most common causes and their solutions so you can know how to troubleshoot them when they occur. While some require technical know-how, most
can be corrected by following the user manual. Let’s get into it.
Faulty Oven Element
An oven element converts electric current into heat that heats the ceramic coating to the desired temperature. The aspect might burn out or wear out over time due to excessive use. Should this happen, it can lead to uneven heating or inability to reach a desired temperature level.
Solution
- Unplug the oven from its power source. Alternatively, you can switch off the circuit breaker.
- Has the LG electric oven been placed in an open area so you can easily access the back?
- Locate the heating elements. Depending on your oven’s model, this can be baked and broiled. They are found at the top or bottom of the range.
- Inspect the elements for physical damage, such as breaks, cracks, or burns.
- Use a multimeter to test their continuity. If there’s no continuity, you’ll need to replace them.
- Make sure to consult the user’s manual when replacing the baking element. While the steps vary depending on the model, removing and replacing the old with new elements will do the trick.
Incorrect Thermostat Calibration
Another reason your LG electric oven is not heating past a specific temperature might be incorrect thermostat calibration. Ideally, the thermostat responds to changes in temperature during cooking, signaling for more or less heat.
If you’ve been using the oven for an extended period, the thermostat may become misaligned, leading to sporadic temperature discrepancies.
Solution
- You need to purchase an oven thermometer to measure the actual temperature inside the oven.
- Preheat your LG oven to a specific temperature, such as 350 F.
- Once it heats to the desired temperature, check the thermometer’s reading.
- If there’s a difference, you should calibrate the thermostat.
- Consult the LG oven user manual for specific steps to calibrate your oven.
- Most LG ovens will work with an adjustment to 35 F.
The calibration process involves accessing the thermostat control panel and making minor adjustments until you achieve 35 F.
Blocked Oven Vents
Oven vents ensure that your LG electric oven is heated evenly throughout. Located at the top and bottom of the oven cavity, they allow air circulation while releasing excess heat and moisture from the oven.
As such, they allow you to bake up to a certain temperature level. If the vents are blocked or unclean, they can prevent proper hot air circulation. This can lead to overheating or not heating at all.
Solution
Material to use:
- Warm, soapy water
- Dishwashing detergent
- Soft cloth
- Oven-safe cleaner/baking soda (optional)
- Small brush
If the vents are clogged with food particles and debris, follow these steps:
- Unplug the oven from the power source. Also, ensure the oven is cool to the touch. Clean vents only when the oven is hot.
- Place the oven in an open area for easy cleaning.
- Remove the oven racks and other removable parts to access the vents easily.
- Locate the oven vents. They are located at the back or top of the oven, near the stovetop.
- Mix warm water with a few drops of the dishwashing detergent in a bucket. This helps remove grime and stubborn stains.
- Clean the vent’s exterior cover by dipping the soft cloth in soapy water and gently wiping away visible debris.
- To clean the inside of the vents, you can use an oven-safe cleaner or baking soda paste. If you prefer using an oven-safe cleaner, consult the manufacturer’s manual.
- Use a small brush to clean hard-to-reach areas inside the vents.
- Rinse the vents with a damp cloth to remove any cleaning residue.
- Use a dry cloth to dry the vents.
- Replace the oven racks and other removable parts.
- Dry the exterior of the oven to remove any residue.
- These steps should help unblock the vents, ensuring optimal hot air flow.
Faulty Oven Sensor
A faulty oven sensor can cause your LG electric oven not to heat past a specific temperature. The sensor is responsible for monitoring the temperature of the oven. If faulty, your oven might not heat to the desired temperature.
The sensor can become faulty due to physical damage, such as being dropped or bumped. Accumulating dirt and debris on the oven sensor can interfere with its ability to monitor temperature.
Prevalent electrical problems, such as voltage spikes, can damage the sensor, leading to inaccurate readings. Finally, everyday tear and wear will eventually affect the sensors, causing them to become faulty.
Solution
To fix a faulty oven sensor, you’ll need to replace it with a new one. Consult the user manual for specific instructions, such as which model of sensors to replace. Ideally, you should follow these steps:
- Disconnect the oven from the power source and ensure it is fantastic to touch.
- Locate the oven sensor in the oven cavity near the baking element.
- Remove the oven racks to access the sensor quickly.
- Remove the old oven sensor.
- Install the new oven sensor.
- Replace the oven racks and connect the oven to a power source.
- Test the sensor
To test the sensor, heat the oven to a specific temperature. Place an oven thermometer inside the oven and wait for the oven to preheat to the desired temperature. Compare the reading on the thermometer to that of the oven. If the lessons are similar, the sensor is working correctly.
Power Issues
If your oven is not getting enough power, it might not heat past a specific temperature. This can be due to a faulty electrical outlet, tripped circuit breaker, or other power issues. Try plugging the oven into a different electrical outlet.
The control board might be faulty if your LG electric oven receives adequate power but cannot heat past a specific temperature.
A defective control board might set the wrong temperature, leading to under or overheating. Consider replacing it with a new one, as this is easy.
You might also need to reset the circuit breaker. Should this still not work, consider consulting an electrician to troubleshoot the problem.
Conclusion
As you can see, several reasons can cause your LG electric oven not to heat past a specific temperature. Fortunately, the problems are easy to fix, especially following the user manual.
If the cause is a faulty sensor, ensure to replace it with a new one. Moreover, ensure the replacement parts are compatible with your LG electric oven model. Finally, remember to take good care of your oven.
Periodic maintenance, keeping it clean, and using the correct replacement parts will ensure your oven works within the preset temperature levels.
