LG LRM1230W Microwave Oven - Page 7 Questions & Answers
LG ldg3016st has no power on main control panel
Did you have any power surges in the house? Any thunder storms?? even if you are not using a microwave, but it is plugged in , you see the clock?? That means it is getting power and running the clock so while you may not be cooking in it, it is actually using power to run the clock functions. So, if there was a power surge, it damages a part on the main board called the Low voltage transformer. It takes the 120 volts from the wall and drops it down to the voltages the board needs to operate, sometimes 5,12 24 or maybe 30 volts. If the primnary winding gets damaged from a surge of some sort. it will no longer light up if that small transformer was damaged. That can happen without even blowing the fuse as the small wires in the transformer were never meant to carry the 15 or 20 amps the fuse is rated at. So the transformer goes bad and the unit is dead but no blown fuse. Have to check the primary winding of the low volt transformer to see if it has continuity. If not, will need new main circuit board. Sorry But $$$$$
