Customer Ratings & Reviews

Hi there, MeganH. We understand your inquiry about the MVEM1825F over-the-range microwave and appreciate you sharing these details. It’s concerning to hear that your unit required service twice within nine months due to heating issues, so let’s review a few steps that may help identify or prevent recurring problems:

1. Verify Power and Installation: First, please confirm that the microwave is receiving proper power and is securely mounted. Check that the dedicated 120 V, 15 A circuit breaker hasn’t tripped. Unplug the microwave (or switch off its circuit breaker) for a full minute, then restore power—this “hard reset” can sometimes clear control board anomalies. Also ensure the unit is firmly anchored under the cabinet; if it’s slightly tilted forward, it may cause internal components like the magnetron to overheat.

2. Inspect the Door Seal and Latch Mechanism: A door that isn’t closing fully can cause intermittent heating. Open the door and examine the gasket and latch for any debris or misalignment. Wipe the door frame clean with a soft, damp cloth—any obstruction can prevent a proper seal, causing the microwave to refuse to heat or shut down mid-cycle.

3. Use Sensor Cooking Appropriately: The MVEM1825F’s sensor cooking function relies on its humidity sensor to adjust cooking time and power. If you frequently cook foods with high moisture content (such as steaming vegetables or soups), the sensor may shut off heating early to prevent overcooking. When testing whether the microwave is actually failing to heat, try selecting a simple “Time Cook” setting at 50 percent power for two to three minutes with a cup of room-temperature water in the center of the turntable. If the water does not warm at all, that confirms a heating component failure rather than a sensor behavior.

4. Monitor Internal Temperature During Use: Over-the-range microwaves have built-in thermal cut-outs that shut down the heating element if the internal temperature exceeds safe limits. Make sure the vent filters are clean and that the external exhaust (if ducted) is not clogged. Restricted airflow in the vent can cause heat buildup, triggering the thermal fuse to open and stop heating. Remove and wash the charcoal or aluminum filters every month, then run the microwave on “Vent Fan” alone for a minute to ensure the blower is unobstructed.

Because your MVEM1825F has already seen multiple repairs, we want to prevent future inconvenience by making sure no underlying part—such as the magnetron, high-voltage diode, or thermal fuse—is repeatedly failing due to installation or usage conditions. At this point, we recommend reaching out directly so our technical team can collect details (like service history, photos of the installation, and serial number) and determine whether a replacement magnetron or other component can provide a long-term solution under warranty.

Hi, there. Thank you for sharing your feedback about the LG Microwave (MVEM1825F) model. We understand your concern about the Express Cook feature and the performance of the exhaust fan. We strive to provide reliable, top-notch products that exceed our customer's needs. For the Express Cook feature, this is designed to start the microwave immediately upon pressing a preset button. However, you can use the manual cook settings or dial in your desired cook time to have more control over the cooking process.

Regarding the exhaust fan noise and lighting, we recommend checking if the fan’s settings can be adjusted or if there’s an option to replace the bulb with a higher wattage or more efficient LED bulb, if compatible. This can help improve the light output.

Hi, JalilN. Thank you for reaching out and sharing your experience with your LG Microwave (MVEM1825X) model. We understand the importance of having your appliance operate reliably, especially after only a short time of use.

One step you can try is performing a power reset by unplugging the microwave for about 5 minutes, then plugging it back in to clear minor electrical glitches. Also, ensure the door is closing fully, and the latch is engaging, as misalignment can cause the unit to stop mid‑cycle.
