Question about LG LMVM1945 Microwave Oven
Some newer models have a child lock feature which can be accessed via a HELP or CUSTOM HELP pad. On recent LG models, try pressing the "0" key for 5 seconds. You may also have a bad keypad, which in many cases can be replaced. A bad keypad may be worn out due to age, damaged, or it may have gotten wet or otherwise contaminated. Has anyone ever sprayed cleaner directly on the keypad? Has anyone ever boiled on the stovetop without running the hood vent fan? Is the hood vent clogged? Any of these can cause moisture buildup on the control circuit board or in the keypad, which can cause odd problems like this. I warn my customers to never spray cleaner directly onto the microwave keypad, since the liquid can get inside and "lock up" or even ruin the keypad or controller. Apply an alcohol-based cleaner (such as the purple kind) to a cloth (since paper towels can scratch) and gently wipe it off. I suggest to my customers that they NEVER use any ammonia-based cleaner (like the blue stuff) on a microwave, since the ammonia will crack and distort polycarbonate plastics. Please let me know if I can help further: http://tinyurl.com/yzjozk
