Totally dead Samsung OTR Microwave Mod ME18H704SFS Ser 07867WTF700650E. This unit is about 16 months old, it belongs to my son. It has worked fine since we installed it. He went away for the weekend, came back home and the unit was totally dead. Nothing. No lights, no panel, no fan. DEAD. Tried a new outlet on a different, (known good) circuit. Same thing. DEAD !!. there was no bad weather or any other signs of electrical malfunction in the house. It is on a dedicated 20 A circuit. I couldn't find a schematic for it. I guess gone are the days of including one with the appliances. After properly discharging the HV cap, I tested as many components as I could easily get to. Fuses on the power board were good. All (I think I found 3) thermal switches/cutouts had continuity. I am not sure I was able to get to ALL the door switches (or for that matter, all the contacts on all the door switches) but the ones I was able to get to tested fine on open/close. I was able to test for AC up to the power board. I did not go into any board components further. When I was testing the thermal cutouts and the door switches, I was careful to remove at least one connect or from each before testing it. All connectors looked fine, and disconnected / reconnected without incident. EXCEPT the one on the thermal cutout for the magnetron. The thermal cutout on the magnetron had one normal looking connector, and one that was badly heat discolored. possibly slightly melted and because of it's location, I was not able to get the required "oomph" on it to disconnect it. I tried wiggling it, pulling it, I tried some needle nose pliers. I just couldn't get a decent grip on it. So I disconnected the normal, unblemished one, and tested continuity fine via the contacts on the cutout itself, NOT via the connector crimp. At this point I had gone as far as I could/wanted to without a schematic. As a "last ditch" effort before calling it a day, I plugged it back in and all was well. It fired right up, heated fine. I remounted it on the wall and it's been good for the last 24 hours. My guess is that one of the connectors I wiggled/removed/reattached etc while testing fixed the issue. Which one? My guess is probably the discolored one on the mag cutout. But who know at this point. Next time I'll test one thing at a time and try to fire it up each time. Any other thoughts, comments or suggestions? Thanks.

Hello Appliance Gurus, I am having a weird issue with my year and a half old LG microwave. It heats (although when running it sounds quieter than it has before, unless it's just in my mind). Oven light works fine. However, when I try to turn on the counter light from the keypad, it clicks as if it turns it on but the light does not turn on. I did replace the bulb to make sure it was good. The same thing happens with the exhaust fan - any button press produces audible click and the speed selection is displayed on the front panel but the fan itself never comes on. Where do I start troubleshooting this? Any pointers would be greatly appreciated!
