I checked the microswitches.The top and bottom one has continuity when plunger is closed or pushed in. The middle one has continuity with the plunger open or out I chased the fuse with cermaic one and has continuity. what am I missing.
1 Answer Hello James. Based on the information you provided, it sounds like the control board Is bad and will need to be replaced in the unit. Read More...
Richard K February 05, 2017 for Model Number 721.85063010 I think I have the same symptoms as others. I can easily get to the switches (by removing vent cover and then a single screw to remove control panel). Here's my question (and it's one about personal safety): Can I remove/replace these switches in a safe way without discharging the capacitor in the machine? In other words, will there be high voltage at any of the switch terminals? I haven't ordered switches yet as I am not sure if I need all three (there looks like there are two "open" switches that are closed when door is closed and then an additional switch which is very near the lower switch.
1 Answer Richard, You are able to remove the power from the unit and change the switches without discharging the capacitor. Read More...
Deb B June 16, 2016 for Model Number 72167903600 Buttons do not respond 99 % of time. Start doesn't work at all. Sometimes I can get the 2 button to work but right now it's in a locked mode that will not release. I took the panel out and checked the seating of the ribbon, cleaned everything, checked all connections I found and it still doesn't work. Any thoughts?
1 Answer Deb, The most likley issue with the unit will be a faulty keypad which is part number 383EW1A093K. Read More...
Steve May 06, 2016 for Model Number 721.69129010 I just ordered a door switch (bottom primary) for my microwave, Kenmore model 721.69129010. How do I easily remove it without breaking any plastic parts holding it in? Probably easy but looks tricky. It is mounted on a plastic peg but there is a plastic bar above holding the switch. Does it just slide out? I was referred to you by the chat room.
1 Answer Hello Steve. You will see some plastic clips holding the switch in place. You will flex those (being careful not to break them) and slide the old switch out. Then slide the new switch into the clips to secure it. Read More...
Yvon March 19, 2016 for Model Number LMV1680ST Hello, After removing and re-installing the microwave door (for helping me to change the upper grill) the board is running except the start buttom doesn't working. All the other buttoms working fine. What would be the problem?
1 Answer Yvon, You will want to check the connections at the control board to ensure that all of the connectors are fully seated especially the ribbon cable. If this checks ok then it sounds like there could be a pinched wire or a faulty control panel . Read More...
Leo W June 04, 2015 for Model Number 72163664300 The internal fan is on all the time until the unit is unplugged?
1 Answer Hello Leo. Test all the door switches in the unit. If one is bad, it will cause that issue. If all of those are good, then replace the control board. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
J.A. May 16, 2015 for Model Number LMAB1240ST My LG microwave turns on (light, turntable, fan, not sure about the magnetron) whenever I press the latch button to open the door. The machine operates normally otherwise, but I must always unplug it before I attempt to open the door. I suspect a malfunctioning switch. Is this a difficult repair?
1 Answer Hello J.A., This sounds like a bad door switch. It is not a difficult repair and the unit will not have to be removed from its' installed position to perform the repair. You will need both top and bottom switches (3B73361E X two), and the center switch 3B73362F. Read More...
Raul November 25, 2014 for Model Number LMVM1935SB Mw will not cook. When we push buttons to start you hear a click but oven does not come on, the timer counts down like it is on. All buttons on control panel work. It acts like it is working but isn't. Light and fan works.
1 Answer Hello Raul. You will need to test the door switches in the unit. See if any are bad. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
Riff Tiff February 21, 2014 for Model Number LG modle #LRM126050sw The part I'm looking for is, what I would call the "start switch". When the door is being closed, the lower Latch pushes against a lever, which fell off. Guess it's part of the "start switch"? What part # would that be? Thank You Riff Tiff
1 Answer Riff Tiff, The part that would push up on the latch that releases it is the lever release part number 4510W3L003A. Read More...
Microwaverepair December 13, 2013 for Model Number 721.66463500 No power to microwave. Replaced and tested both fuses, tested continuity for all switches and tested capacitor. Could it be the high voltage transformer or is it some other part? Thx.
1 Answer Hello Microwaverepair. It has to be the control board if all the other parts are testing good on the unit. Read More...
