If your LG 2.0 Cu. Ft. Countertop Microwave with Sensor Cooking and Smart Inverter - Stainless Steel, Model # MSER2090S, runs but doesn't heat, that is typically caused by a failed magnetron, high-voltage diode, or door switches. Common causes also include a blown high-voltage fuse, defective capacitor, or the unit being in Demo/Store Mode.
The magnetron is the core heating component. If it fails, the microwave runs but won't heat.
 If the door doesn't securely trigger the switches, the magnetron will not activate.
To disable the Demo mode, open the microwave door. Press and hold the Clock button or the Stop/Clear button for about 3-5 seconds.
Some models may require you to press the Clock button repeatedly until "DEMO MODE" appears, then press Start to toggle it off.
If the display shows "oFF" or the demo icon disappears, the mode is deactivated.
Close the door and test it by setting a short cooking time...^Ivan.
