i unplugged the unit,unscrewed the outer shell so that all the wiring and internal components were visible.starting at the first of three micro switches i removed the slip on terminals installed the alligator clips too the wires so the switch would now be bypassed.i made sure the wires and clips were not touching anything plugged unit in and it worked.i then installed the new switch and closed up the outer shell
Initial failure of over range microwave Aug 3rd. Control Panel worked but no heat. Took to local LG authoriaed local repair place. They fixed it quickly and we re-installed it. Worked fine for 2 months then had similar failure again. Agaim took to same authorized repairer. They kept unit for 3 months but finally concluded theu could not fix it and suggested we contact LG for a partial refund. When they tested the unit during re-assembly in my presence, there was a blue flash and the fuse blew. Since we had built a custom tile mural back splash around this unit, I brought it home, ordered a number of time delay fuses new capacitor and two new high voltage diodes. However, using my Fluke DMM, I checked the existing capacitor and high voltage diode and they checked OK so I just replaced the time delay fuse. The high voltage transformer leads had 2 possible ways to connect to capacitor and diode. Tried one way, plugged unit in and turned it on, and immediatly blew the fuse. Replaced the fuse and reversed the high voltage transformer connections,amd turned unit pn, and it worked perfectly. Since we had experienced several power failures during the time of the original failure, the repairer concluded that power spikes might be at fault, so I also purchased a TrippLite ISOBAR4ULTRA 3300 Joule surge protector between wall outlet and microwave, and re-installed over range. It has worked perfectly since.
Vent grill was old and breaking apart and air filter was greasy
Unscrew the vent grill and took it off. Then remove the air filter and clean off the surrounding area. Then install the new air filter and vent grill. Put on the two screw and i was done. All done in less than 10 minutes.
My wife was pushing a few buttons with her knuckle (hands were full)and the microwave just turned off. Just like we had blown a breaker. First I unpluged it. Then I removed the phillips screws of the front panel, and found and removed the ceramic fuse. 3 days later I received the new fuse in the mail, and put it in. I plugged the microwave back in and it works great.
Microwave failed to head and light, fan, and turntable failed to come on.
Problem was due to a faulty door switch. Replaced with a new switch and the microwave now works fine! Only thing that was tricky was that LG uses the hex screws with a peg in the middle to keep the microwave cover on. Had to use a small screwdriver and pliers (on the screwdriver) to unscrew the screws.
The problem I have with changing the bulb is my microwave is an overhead one and therefore I cannot tip it on its side to easily replace the bulb. I have to drop the lid down and carefully install the new bulb from underneath.
I received my glass cooking tray so fast but when I try to put in the microwave did't fix was to big,I call you today to return and very nice lady help me and told me I need to call whirlpool and explain them and already order again thank so much for all your help you have very nice people in customer service. Thank you so much again. !!
First let me say that I tried several places to get what I thought was a simple light bulb. This included several national hardware stores as well as a national electrical supply company. No luck. Went to the manual and PartSelect. Not only did you have it in stock, ship right away,at a reasonable price it arrived in a matter of days. One would not normally think of receiving a "how to" video to change a light bulb but you did. That impressed me. Suffice to say the replacement went well and you can be certain the next time I need a part I will go to you first. I am also impressed with the organizations with which you are affiliated with. BBB, Norton, PayPal, money back guarantee etc. Thank You The entire process was made pleasant with your support.
