What to do if my LG MS-7042MK does not work?
If your LG Microwave Oven isn't working, first ensure the plug is securely inserted. If that's not the issue, check that the AC input voltage is adequate. Also, consider that if the food temperature is too low, it may simply need a longer cooking time.
Why is my LG MS-7042MK not heating properly?
If your LG Microwave Oven seems to be operating but produces little heat, the output rating voltage may be lower than 90%. It is suggested that the customer contact their local electric power utility company or a qualified electrician. Also, a defective PCB assembly or magnetron may be the cause. In these cases, replace the PCB assembly or the magnetron.
What to do if LG MS-7042MK Microwave Oven won't turn on?
If your LG Microwave Oven does not operate at all, the display window shows no figures, and no input is accepted, it could be due to a malfunction of the monitor switch, a defective thermostat, or a defective power supply cord. Replace the fuse and check the continuity of the monitor switch. Replace the thermostat or the power supply cord.
How to fix LG MS-7042MK display not counting down?
If your LG Microwave Oven display doesn't count down when you touch the START pad, this could be due to a defective secondary switch, a defective PCB assembly, or a loose connection. Try replacing the secondary switch or PCB assembly. Ensure all connections are tight.
